How To Use This Guide 
1) Yes this guide can save you time and money. You will get the results directly 
because you will know which components you want to replace. This means you 
don’t need to pay more money and time to learn how to troubleshoot LCD TV 
from starting until the end. Before using this guide, you need to know how to 
disassemble the LCD TV first. You need to know some of the basic testing 
electronic components skill and must know how to solder components on the 
PCB board. This guide can help you to solve LCD TV problems on the spot. 
2) Find the solution by comparing other brands or models but with the same 
symptom of your LCD TV. For example, if one of your LCD TV problems is 
OSD Menu auto pop up and you can’t find your model inside this guide, you 
can try to find other brands or model but with the same symptom with your 
LCD TV problem. Then the solution can be use for reference. 
3) This V4.0 –Collection of LCD LED TV Repair Tips ebook was different than 
other previous volume V1.0, V2.0 & V3.0. The V1.01 & V2.0 are more on 
repair tips or problem solution only. The V3.0 is more on special and details on 
that subject. But you can learn and use the knowledge from it to apply to other 
brands and models of LCD/LED TV. 
4) After you have finished reading this guide, I believe you will have the 
confident to repair LCD TV now. The reason for it is because you now know 
what is the most common fault inside the LCD TV’s and what are the common 
parts that need to be changed.

LCD & LED TV Repair Tips 
 
Note: Most of these repair tips are not included the fault of electrolytic 
capacitors! Because of the electrolytic capacitor bulge or bad on ESR values are 
easily detected by the ESR Capacitor Tester. Before read these repair tips, 
please make sure that you had testing the electrolytic capacitors first. 
 
1) Model: ChangHong LED32B1000C LED TV 
Symptom: No Power, Dead 
The Power Supply board is using HSS35D-1MF 
Repair/Solution: 
Open the TV rear cover, look at the PSU board and can’t find any burn 
component on it. Checking the F101 main fuse is ok. Power on the TV, their 5V, 
12V & 24V all no outputs. Suspect the PFC section failure. Measure the big 
filter cap is only 302V, instead of 380V! That’s mean their PFC section not 
working. So power off TV and using the Multimeter testing the PFC circuit 
components and found that Q108, Q109 and Q110 (all are 2T (4403) marking 
code, SMD) all are gone. So using the 2A (3906) SMD as a replacement and the 
TV is working properly. Actually this is a common fault in this PSU HSS35D-
1MF board. 
2) Model: ChangHong LED43A9000i LED TV

distortion or no display. Normally this type of problem is difficult to diagnose. 
This LED TV using Samsung LTA43HN01 LED Panel, T-CON board is 
K160HZC2LV0.1. From the above fault picture, suspect the LVDS cable, T-con

3) Model: LG 60LS5700-UA & 60LS5750-UA LCD TV 
Symptom: No Display but Sound is Normal 
The TV front buttons are all working well. 
Repair/Solution: 
The Power Supply voltage outputs are all normal. This TV backlight is lit and 
the sound is OK. The T-con board Vcc voltage 12V was present. That’s mean 
their backlight system, PSU board and Main board are all OK. 
 
So suspect the T-con board failure. Power off the TV, measure the T-con board 
SMD fuse (5A, 32V) was opened. Before replace the fuse, check the Vcc line 
and found that their ohm value is very low (below 100 ohm). After trace the 
Vcc line to IC301 (17140E) and confirm that this IC was shorted. Because of 
this IC no stock, so direct replace this T-con board (p/n: AGF76630001) and the 
problem solved.

1. With the TV in Standby mode, measure pins 2, 3, 8 and verify that the DC 
voltages are correct. If the voltages are missing or not correct, check the cabling 
and voltage supply feed from the Main board. 
2. Turn on the TV, measure pins 2, 3, 8 and also pin 1for correct DC supply 
voltages. If the voltages are missing or not correct, check the cable and supply 
feed the Main board. 
3. Now measure pins 4 and 5 which are the Bluetooth signals. If the voltages for 
pins 4 and 5 are missing or not correct in the Power On state, the problem is 
likely the Bluetooth module. 
 
 
Note: For other brands and model TV with Bluetooth Module, their 
troubleshoot method is nearly same like this repair tips. So you can using this 
tip as a reference.

Page 21 
Repair/Solution: 
Picture 1 shows the problem: Red solarisation on the bottom of the screen. Your 
first impulse is probably to replace the panel, but if you look closely, you’ll 
notice that solarisation appears only on the right side of the screen. The left side 
does not show the problem. This tells you it’s not a panel issue. What should 
you consider? The signal source PCB, or LVDS cable connections. 
To see if it’s a signal source issue, enter the service mode and check the test 
patterns. This is shown in Picture 2. Notice that in service mode, the right side is 
all Red, showing you that the signal source is not the problem. This leaves three 
items as the probable cause: the Main board, the LVDS, the T-con board or the 
FPC cable. In this case, the cause was the LVDS cable connector on Main board. 
It was not closing tightly enough. Putting hand pressure on the connector there 
caused the problem to come and go. 
So try to using the strong tape or silicon glue to fix the connector and prevent it 
loose again. So the TV problem was solved.

If the lines appear in the Picture Test/OSD Menu, the cause is a bad panel. If the 
lines do not appear, disconnect all signal sources and check again. If the lines 
are still in the Picture Test, checking the LVDS cable contacts or change the 
Main board. If the lines are gone, then a signal source is causing the problem.

13) Model: Samsung LN32D450G1D LCD TV 
Symptom: The Screen has Double Vertical Lines 
 
 
 
Repair/Solution: 
If the lines appear in the OSD Menu, the cause is a bad panel. If the lines do not 
appear, disconnect all signal sources and check again. If the lines are still over 
the OSD Menu, so checking the LVDS cable contacts or change the Main board. 
If the lines are gone with different video signal input, then a signal source is 
causing the problem, so you need to trace that video input circuit to find out 
what’s wrong in it. 
But most of the time, this type of symptom were causing by the LCD Panel, bad 
COF contact in between Source Driver board or the other side of the Panel glass 
contact pins.

Symptom: The Screen One Side is Darker than the other. 
 
 
Repair/Solution: 
Try to call out the OSD Menu. If one side isdarker than the other, it’s a bad T-
con board or FPC cable. If the OSD Menu is fine, then checking the LVDS 
cable and main board. Most of the time is their FPC cable contact pins dirty. 
After clean the screen problem solved.

15) Model: Samsung UN60D7000 LED TV 
Symptom: These’s a Thin Vertical Line on the Left Side of the Menu 
 
 
Repair/Solution: 
Try to call out the OSD Menu or Smart Hub Page. If the line goes through the 
OSD Menu or Smart Hub like the picture above, the panel is bad. If it’s behind 
the OSD Menu, disconnect all signal sources and check again. If the vertical 
line is still behind the OSD Menu, then checking the LVDS cable or replace the 
main board. If the line is gone, then the signal source is the problem. 
Or try to use the finger to touch or knock the top cover of that line position. If 
the line can missing randomly, that’s mean their COF or TAB contacts was dry 
join on the Panel.

After you have changed the HV FLIP setting, power cycle the TV (turn it off 
and then on) to lock in the setting. 
Note: Whenever you replace a main board or lcd panel, always refer to the 
OPTION BYTE list to verify that the settings are correct. Option Bytes mainly 
match the correct drive to the panel, but can also have effects based on feature 
functionality. Some of the settings, if not set correctly, may cause minor defects 
in the overall operation of a TV. These defects are often not immediately 
obvious and may be discovered by the customer days after the repair.

normal and stable. The inverter board 24V input voltage also OK. So the 
problem looks like is the inverter board. Checking the inverter board MOSFET, 
HV Transformer and caps all are OK. So replace the inverter IC BD9893F and 
the problem solved.

19) Model: TCL L32E09 LCD TV 
Symptom: Stuck in Standby Mode 
Repair/Solution: 
This LCD TV look like dead, but when checking their Backlight and PSU 
voltages all working properly. But the Main board PS_ON signal is missing. 
When testing the Main board all LDO DC-DC circuit, 5V, 3,3V, 2.5V and 
1.27V are normal and stable. Try to using the Remote Control or front button 
also not working at all. Measure the flash memory IC U104 (S25FL040A) Vcc 
voltage input is OK, their Main Chipset can feel some warm temperature. 
So suspect the TV is their firmware corrupted. Use the ISP Programmer, first 
checking their Initial Serial Print Info and found that all information is garbled. 
Try to re-programmer their firmware, but also no help. So the last suspect is 
maybe their Main Chipset (U112, BGA type) or the crystal X100 
(14.31818MHz). Replace the crystal X100, the problem solved! Try to using the 
ISP Programmer to checking their Initial Serial Print Info, all are ok now.

20) Model: TCL L46E5300A 3D LED TV 
Symptom: TV No Sound after 1~2 Hours 
Repair/Solution: 
When testing this TV, after about 1 hours, the sound will randomly on and off, 
after that totally no sound. So try to using other signal input like AV and HDMI 
also same symptom. 
Because of this TV after warm up the problem will occur, and then suspect that 
Main board Audio section has component sensitive with heat increase. Try to 
using the Hair Dryer to shoot to the Main board Audio section and found that 
just using about 10 minutes, the TV no sound symptom occur. So confirm that 
the Audio section is the causing this symptom. When testing the U701 
(TAS5707) each pins, found that pin 19 (control MUTE function pin), when TV 
has normal sound it is about 3.3V. After the hair dryer shooting to Audio 
section, it is slowly drop to 0V and the sound gone! 
So suspect their MUTE circuit has component fail/sensitive after heat increases. 
Use hair dryer to concentrate shooting on this circuit and found one SMD 
capacitor C735 (1uF) leakage and sensitive in heat increase. After replace this 
cap, the TV no sound problem solved!

Symptom: TV Channel No Display, but Other Signal Input Normal 
Repair/Solution: 
Check the PSU board output voltages normal, Main Board LDO (DC-DC) 
output voltages normal and stable. Checking the TV Tuner all voltages OK, but 
found that their clock signal lines SCL and SDA was drop to 0.8V, normally it 
is about 5V. These two lines are go to the Tuner section, so disconnect these 
two lines, the SDA & SCL lines are back to about 5V! So trace these two lines 
to the Tuner section and found that Tuner socket got two pins was shorted. 
After re-solder these two pins, this TV problem solved!

How to Isolate the LCD TV Problem Fast 
I’ve receive lots of the email to ask me how to repair the TV no display problem 
or etc? But they are never provided more details or information about the TV. 
For example the TV brand, model number (for Philips TV must provide with 
their Chassis Number), TV symptoms, what’s their power supply secondary 
voltage output values and so on. 
Because of this reason, this chapter will help the repairer learn more about how 
to isolate the LCD/LED TV problem before starting repair it. When you know 
how to isolate the TV problem fast, then you can quickly repair the LCD/LED 
TV in board levels repair. So that you need to know about these: 
A) Basic Knowledge 
B) How LCD TV Work 
C) The Method and Tools to Help Isolate the LCD TV Problem 
 
A) Basic KnowledgeBefore starting to check the TV, the very first step is listening to the customer. 
 The TV problem complaint by the owner/customer 
After that, power on the TV to look at their symptom is it same describe as the 
customer complaint. Remember, if the TV complaint shorted and will causing 
the home main Power System shutdown (PLCB fuse/switch activate), this TV 
can’t power on first, but need to open their rear cover to checking their Power 
Supply board first. If the TV problem same as the customer describe, so we can 
start to check the TV now. If the TV symptom is different than what customer 
describe, then we need to call the customer first before proceed it. 
Lots of the LCD & LED TV they have self test system. When an abnormally 
occurs in TV, the self test protection circuit will operate and reset the unit to 
standby mode. During this time, the defective block/board can be identified by 
the number of blinking times of the Power LED on the front panel of the TV. If 
the self test system found that the CCFL lamps abnormal or disconnected, it will 
shutdown the backlight system and then provide the error message or error code 
to let the repair engineer easy to know what’s wrong inside the TV. So their TV

front Power LED light will blink differently, for example: LED light blinking 1 
times then stop 2 seconds and continue to blinking 1 times. To find out what’s 
meaning of these LED light blinking, you need to refer to their service manual. 
But not all the service manual will show their error chart. So you need to search 
other nearest model service manual to compare with it.

If the TV malfunction and show the error code (blinking times), you roughly 
know where to check and repair it. If you’re doing the board level repair, then 
you can direct replace the PCB board to solve the TV problem. Or you need to 
do the components level repair, then you need to concentrate to checking the 
appropriate PCB board, when found the defective component/s, then you can 
direct replace the components and solve the TV problem with the lowest cost 
compare with board level repair. 
If the Power LED light blinking non-stop or with the relay “tic..tac..” sound 
inside the TV, that’s mean something wrong in the PSU board or their loading 
shorted. So you need to check their PSU board first. 
 
B) How LCD TV Works 
 Here is the basic information of how LCD TV works. Actually this 
information/knowledge you must know before you starting to repair the TV. If 
not, you will not sure where to troubleshoot the TV first. 
The whole set of LCD TV is just have 7 parts/PCB in it. They are: 
1) Power Supply Board 
2) Inverter Board 
3) CCFL/EEFL lamps 
4) Main Board 
5) Front Panel PCB 
6) T-CON board 
7) LCD Panel 
Some LCD TV, their use the IP board (Power Supply + Inverter in one board) 
and the T-CON board was built-in the LCD Panel. So some LCD TV just has 5 
parts/PCBs only.

1) IP Board (Inverter Power Supply Board) 
 * The IP Board or Power Supply board feature is use to input the AC 
voltage supply and converter it into DC voltage supply. The IP Board is Power 
Supply + Inverter section built-in it. For the Power Supply Board, it is only use 
to generate the DC voltage supply only. The Power Supply board will generate 
several output DC voltage supply in their secondary side and supply it to Main 
board, Inverter board/section and T-CON board (but this voltage supply will go 
through and control by Main board). 
 * The Inverter Board/Section is use to step up the low voltage (DC 
voltage) to output high voltage (VAC) to start-up the CCFL/EEFL lamps. 
Normally the voltage input to inverter board is 24Vdc and their voltage output 
is about 1500Vac (start-up) and then will steady at 600~800Vac (it will depends 
on what types of lamps in use). 
 * Normally the Power Supply or IP board will generate 5VSTB (standby 
voltage), 24V, 12V, 5V, 3.3V and 18V (or other voltage values for Audio 
section use).

2) Front Panel PCB (Key Board) 
 * This PCB board feature is to input the command from front buttons and 
remote control and then send to Main Board. Some LCD & LED TV design is 
built-in this PCB into the Power Supply Board. 
3) Main board 
 * The Main board has lots of the features inside. It’s function like the 
computer main board. But it can divide to 4 parts: 
 i) With the Main board CPU + MCU (microcontroller unit), its can 
control the whole system through send out the signals. For example the signals 
like PS_ON, BL_ON, PANEL_ON and etc. 
 ii) Process different types of video signal inputs. For example: TV Tuner, 
AV, HDMI, PC, S-Video, USB & etc. After that the Main board will convert 
these video signal inputs to RSDS type video signals and send to T-Con Board 
through LVDS cable. At the same time, the Main board will also process the 
audio signals and amplify it and send to the speaker. 
 iii) The Main board DC-DC section. This is a very important section in 
Main board. This section will received the voltage supply from the Power 
Supply board and generate the appropriate DC voltage to other system use. For 
example, CPU core power, CPU Vcc, DDR RAM Vcc, Tuner Vcc and all 
analogue and digital circuits use. 
 iv) If that is SMART TV with 3D, WIFI & etc features, so these TV Main 
board will have add in or built-in 3D or WIFI features card/plug-in into the 
Main board. 
4) T-CON Board 
 * The T-CON board is use to receive the LVDS format video signals and 
convert it into TTL (Transistor Transistor Logic) or RSDS (Reduced Swing 
Differential Signaling) signals. These signals can driving the LCD Panel to 
working and generate the complete display in the screen. 
 * Not only that, the T-con board has another important section, which is a 
DC-DC circuit. This DC-DC section received the voltage supply (Vcc) from the 
Power Supply and through the Main board. After that, convert it into several 
voltages and supply to the T-con board and also to driving the LCD Panel too.

5) LCD Panel 
 * The feature of LCD Panel is to convert the video signals into a 
complete display or picture in the screen. 
6) The CCFL/EEFL lamps were inside the LCD Panel 
 * If the LCD Panel without the backlight, the screen will darkness and 
hard to see their contents or display. The Backlight system is using the 
CCFL/EEFL lamps (with the voltage supply from Inverter board) or LED strip 
(with the voltage supply from LED Driver board) to generate the back light. 
 
A Simple Description of How LCD TV Work 
When the TV power cord connects to AC supply and switch it ON, the LCD TV 
PSU board will automatic received this AC voltage input. After that the PSU 
board will automatically generate the Standby Voltage 5V (5VSTB) and send to 
Main board. They are not any other voltages in PSU board except the 5VSTB. 
When the Main Board received the 5V standby voltage from PSU board, it will 
going through a voltage regulator IC or DC-DC circuit to generate the 3.3V 
voltage. After that, this 3.3V will supply to MCU (microcontroller unit) IC, 
CPU and the Front Panel board. So that we can see the standby LED light is lit 
in front of the TV. The TV is in the Standby Mode now. 
After press the power on switch button in FrontPanel board or remote control, 
the Main board will send out the Power On signal (PS_ON, PWR_ON or etc 
marking code) to PSU board. This PS_ON signal will send to Power Supply 
board PFC section and then the PWM section to generate other voltage outputs 
like 24V, 12V, 5V, 3.3V and etc to Main board, T-con board and Inverter 
board/section. Finally the TV can show the display now.

C) The Method and Tools to Help Isolate the LCD TV 
Problem 
In this stage, we must have some electronic testing skills to troubleshoot the TV. 
If you think your skill is not enough to do that, then I will highly recommend 
you read these e-books: Testing Electronic Components & SMPS Power Supply 
Repair Guide at: 
http://www.lcd-television-repair.com/newsletter/Recommend.html 
Here is the list of TV problems is always occurring in LCD TV: 
 
1) No Power/Dead (no any LED light lit in front the of Front Panel board) 
 * If the TV is No Power symptom, first need to check their Power Supply 
AC input after fuse is appear or not. If it is appear 110Vac or 220 Vac, that’s 
mean the AC input, power switch and fuse is ok. If not you need to check the 
AC plug main switch is press ON or not. Check the power cord and the fuse 
also. 
If the 110Vac or 220Vac appear, but PSU secondary side no voltage outputs 
then you need to replace a working PSU board to solve this problem. If their 
Standby voltage 5V is appear but other voltages are no output then you need to 
check the Main board and the Front Panel board. If you have learned the V3.0 
ebook, then you can use the PSU self test method to confirm it is the Main 
board or backlight problem. 
2) No Display & No Sound (but the LED light is lit or LED light blinking) 
 * When the TV No Display but the LED light is lit from Red change to 
Blue or Green color light, that’s mean the Main board has sent out the start-up 
signal to PSU board. But the actual situation is we need to know the PSU board 
has output all the voltages correctly. So that still need to checking the PSU 
board secondary side output voltages is normal and stable or not. If all voltages 
output normal and stable (including the BL_ON and PS_ON signals appears), 
that’s mean the problem is in the Main board. Make sure that’s in the TV Mode, 
if not sure then you must also check their T-con board too. 
 * When the TV No Display but their LED light is blinking nonstop, so 
need to check their standby 5VSTB is normal or not. If the 5VSTB is normal

Page 40 
and stable, also need to know the PS_ON signal appears or not. If the PS_ON 
signal not appears, need to check the Main board and their Front Panel PCB 
board. In this case, disconnect the Front Panel PCB from the Main board and 
power on the TV again, if the TV can show the display normally, that’s mean 
the Front Panel PCB is something wrong happen in it. If after replace the Front 
Panel PCB still same symptom, then need to check the Main board or replace it. 
 * When the TV No Display & No Sound but the LED light is blinking 
few times then stop and continue to blinks, this type of LED blinking is 
showing the error code to the repairer. Regarding this type of symptom, you 
need to refer to their service manual to find out what’s the meaning of this error 
code like I wrote in this chapter (A) Basic Knowledge there. 
3) No Display but Sound Normal 
 * If the TV is No Display but sound normal, sometime we can hear the 
sound from TV channel changed. For this symptom, need to know: 
 a) If their backlight is lit, need to check the T-con board Vcc voltage 
input after SMD fuse. If the Vcc voltage appear (typically it is 12V or 5V), the 
higher opportunity is the T-con board gone. So replace a working T-con board 
to give it a try. 
 b) If this TV backlight is off, need to check the BL_ON & PDIM signals 
are appear or not. If not appear, the problem is in the Main board there. If these 
signals appear, the problem is in the inverter board/section or their CCFL/EEFL 
lamps. 
4) No Display in Certain Video Signal Input 
 * If the TV can show the display in one of the video signal input, but 
other video signal inputs are ok, so this type of TV symptom is causing by the 
Main board. If want to do the components level repair, need to check their 
appropriate section. For example the HDMI section, AV section and etc. 
5) No Display after Several Seconds (or call it as Backlight shutdown) 
 * This type of TV symptom is causing by their inverter board/section or 
the CCFL lamp/s. Before that, make sure their BL_ON and PDIM signals are 
normal and stable. If not stable or abnormal, need to check and tracing it to the 
Main board there. If not sure problem is causing by Inverter board or CCFL 
lamp/s, we can use the CCFL lamp Tester to testing it. So that we can confirm it

Page 41 
is the inverter problem and their CCFL lamps are ok. With this tool, we can 
quickly found that’s the inverter or their CCFL lamps problem. 
6) Display Problem/Abnormal Display 
 * This type of symptom we can divide it into: 
 a) Black Screen/No Display: For this symptom, please refer to the 2), 3) 
& 4) in this chapter. 
 
 b) Grey Screen Problem: This type of problem is same as the 3) a. 
 
 c) Vertical Lines/Bars in the Screen: If the lines/bars is across the OSD 
Menu and all the video signal inputs also same result, that’s mean this TV LCD 
Panel is defective. 
 
 d) Horizontal Lines/Bar in the Screen: If the lines/bars is across the 
OSD Menu and all the video signal inputs also same result, that’s mean this TV 
LCD Panel is defective. 
 
 e) Half Screen Blank but Another Half is Normal: Mostly this type of 
symptom is causing by their FPC cable/s. This cable is output from the T-CON 
to Source Driver board. Besides the FPC cable, their connectors in T-CON 
board and the Source Driver Board must check also. Because some repairer 
after they replace the T-con board and solved this type of problem, but their 
actual problem was because of the connector dry joins or etc problem only. Or 
the Half Screen is Abnormal but another Half Screen is normal then this type of 
problem is causing by their T-CON board. 
 
 f) Negative Picture: This type of problem was because of their T-con 
board GAMMA circuit malfunction. So just replace the T-con board and the 
problem solved.

Page 42 
 g) Display Distortion: For this type of TV symptom, it is hard to say 
which section is defective, but most of the time, it is causing by the T-con board 
or Main board. 
 
 h) Display Full of Vertical Color Lines: This type of TV problem, we 
must call out the OSD Menu to confirm. If the OSD Menu is showing normally 
in the screen but their background is fully of vertical lines then this symptom is 
causing by the Main board or their LVDS cable. 
 
 i) Display is Opposite in the Screen: This type of symptom is causing 
by their Main board firmware setting or firmware corrupted. 
The above information is just for the repairers who want to repair the TV in 
board levels repair only. If you need to do the components levels repair, you 
need to learn more in this ebook and my other series ebook like V1.01, V2.0, 
V3.0 or etc.

Another Main Board Secret Repair Tips 
Nowadays, lots of LCD or LED TV Main board problem difficult to repair it.Even you had checking all the components in the Main board or re-program 
their flash memory IC or EEPROM but no help too. 
So what’s happen to the TV Main board? Why can’t to repair it? But after buy a 
new Main board to replace it, the problem solved! 
Finally, found the answer for this Main board problem. Actually it is causing by 
their Main board LDO and DC-DC circuits!!! Some repairer may said, I had 
checking their voltage outputs properly and values are stable too. Yes, even 
their output voltage value is correct and stable, BUT some of these output 
voltage values are not accept by the Main board Chips like their CPU, DDR 
RAM & the Flash memory! So, is it hard to repair and expensive to replace it? 
NO, it is cheap and easy to get it! 
Note: LDO is stand for Low-DropOut Regulator 
(http://en.wikipedia.org/wiki/Low-dropout_regulator)

The above two sample of DC-DC & LDO Voltage Output Circuits 
 
Note: The LDO circuit normally using the IC like: 1117 series, 1084 series & 
etc. For the DC-DC circuit, it is using the IC like: AOZ1041, AOZ1072, 
AP1534, MP1482, MP2212 & etc. 
 
The Main board problem like: 
1) TV stuck in standby mode because of the POWER_ON signal missing. 
2) The TV Backlight problem and causing by their BL_ON signal missing. 
3) TV some time can start-up but some time not. The POWER_ON signal 
unstable and causing the TV non-stop on and off. 
4) The TV Backlight flickering and causing by the BL_ON signal unstable. 
5) Display Distortion 
6) No Display, even the power LED light change from Red to Blue color light. 
7) And other strange TV problem….. 
From the above TV symptoms, even you had confirm their Power Supply (PSU) 
board is ok, inverter board/section is ok, CCFL lamps or LED strip are ok, T-
con board is ok and even the LCD/LED panel is ok too.

Page 45 
When you confirm that the problem was the Main board, some of the repairer 
will stop checking it, or just measure some common components then replace 
the whole Main board and the problem solved and case closed. 
For some repairer, they will continue to checking the Main board with these 
steps: 
1) Checking the Main board output signals like POWER_ON and BL_ON are 
normal and stable or not. 
2) Checking Main board LDO & DC-DC circuit voltage outputs values is 
normal and stable or not. 
3) If all voltage outputs are normal and stable, they will continue to checking 
the Flash Memory and the EEPROM circuits. 
4) After that checking the CPU (Main Chip) Vcc input voltages, crystal and 
reset circuit. Or try to replace the crystal and give it a try. 
5) Also checking the DDR Ram Vcc and their other signals lines too. 
6) If above steps all also no help, then it can try to re-program the correct 
firmware to Flash Memory using ISP Programmer. Also try to replace an empty 
EEPROM IC into the Main board and give it a try (most main board can accept 
this method, but little Main board will not). Or replace the Flash memory or 
EEPROM IC to give it a try. 
7) If still no help, then replace the CPU (Main Chip). But most of the repairer 
after doing step No.6 they will give up and replace the whole Main board. 
 
Actually the TV Main board CPU Core Power (normally are 1.26V, 1.2V or 
0.9V, it will depends on their design) voltage require very strict to it. For 
example the 1.26V core voltage line, If a bit different voltage values, when 
testing it with 1.29V or 1.3V values, then this voltage is not accept by the CPU 
and will causing the Main board not working or working abnormal. So the 
acceptable voltage values for 1.26V core power will be 1.25V~1.27V. The LG 
42LK530 LCD TV Main board it is using 0.9V of their CPU core power. 
So what will cause the CPU not working or working abnormal except the 
voltage input not correct or not stable? Yes, the answer is the “Ripple Voltage” 
for this CPU core power!

This is a sample voltage output of CPU core power 1.26V 
 
Not only the CPU, the DDR RAM also require the voltage input very strict and 
stable! The Flash Memory voltage input also same too. 
So lots of the TV repairer they don’t know about this, or even know about this, 
but the Oscilloscope also can’t detect this Ripple voltage in the LDO or DC-DC 
output! If this Ripple Voltage over 10mV (some Main board will accept to not 
more than 100mV ripple voltage, depends on the Main board design), the CPU 
will not working or working abnormally. If the Ripple Voltage is below 10mV, 
it is acceptable by the CPU core power system. 
So the TV repairer will think this output voltage is ok and can be trusted 
(Because of the Multimeter and Oscilloscope not detect any abnormal values or 
waveform there). But from lots of the Main board repair case, this Ripple 
Voltage always occurs in CPU core power input and the DDR Ram Vcc input! 
This causing lots of the strange problem in Main board and can’t be repair (the 
repairer don’t know about this) also throw this Main board in the trash can. 
After you learn this tip, if you had throw this type of Main board in the trash can 
before, you will regret it.

The method to solve this Ripple Voltage in LDO or DC-DC circuit is JUST add 
an Electrolytic Capacitor parallel with the voltage output line, if the problem 
gone, that’s mean their LDO or DC-DC output circuit has/have filter capacitor/s 
out of values, bad ESR or etc problem. So just replace the old electrolytic 
capacitor in the circuit with a new one. The values of that capacitor should be 
same or a bit more capacitance than the old one. For example, if the original 
capacitance values are 100uF/16V, you can replace it with 100uF or 220uF/16V 
(use a good quality electrolytic capacitor and its better using 105’C type). For 
the CPU core power DC-DC circuit, normally it will use the 220uF~470uF/16V, 
the DDR Ram LDO circuit will use about 47uF~100uF/16V. The DDR Ram 
(Vcc input and DDR Vref lines) LDO or DC-DC circuit, their output voltage 
line better put the 100~220uF/16V electrolytic capacitor for more stable.

Repair/Solution: 
Open the TV rear cover, testing their PSU voltage outputs. The 24V= 23.8V, 
12V= 12.5V and 5VSTB= 5.04V all are ok and stable. Checking the PR 
ON/OFF signal has 2.65V but the BL-ON/OFF signal not stable. This BL-
ON/OFF signal voltage repeated changed from 4.93V~0.02V. When the 
backlight lit about 10 seconds, this BL-ON/OFF signal has 4.93V, when 
backlight off about 5 seconds, the signal voltage has 0.02V only. 
So suspect the CCFL lamp/s or the inverter board failure. Use the PSU self test 
method (I had mention it in my V3.0 ebook before), to testing the PSU and the 
backlight system. Surprisingly, PSU board and the backlight system are 
working properly! 
The BL-ON/OFF line disconnectto inverter board and testing it in the Main 
board there. Found this BL-ON/OFF signal voltage still up and down. So 
confirm that the problem was in TV Main board. 
The steps to checking the TV Main board are: 
1) LDO and DC-DC circuits 
2) EEPROM and Flash Memory circuit 
3) CPU Reset circuit 
4) CPU Crystal 
5) DDR Ram circuit 
6) Try to replace the firmware for Flash Memory with ISP Programmer 
7) Replace DDR Ram or CPU chip or just replace a new Main board. 
 
To checking the LDO & DC-DC circuits in TV Main board, we need to use the 
Main board schematic diagram to know how many LDO or DC-DC circuits in 
this board. Below is the voltage output value of this Main board: 
1) U2 (LDO) 3.3VSTB= 3.331V 
2) U3 (LDO) DDR_1.8= 1.818V 
3) U4 (LDO) ADC_33= 3.351V

4) U12 (LDO) 5V_IF= 5.02V 
5) U21 (DC-DC) 5V= 5.03V 
6) U25 (DC-DC) VDDC= 1.273V (CPU core power 1.26V) 
7) U26 (DC-DC) 5V_USB= 5.02V 
The above voltage values look like normal and stable. So the next step will be 
checking the EEPROM and Flash Memory. So measure the EEPROM Vcc 
input, SCL & SDA signals, all are good and stable. The Flash Memory Vcc 
input and the CLK signal also OK. 
 
 
So continue to checking the CPU reset circuit and the crystal waveform. The 
Reset Circuit is operating properly. When checking the Crystal, the oscilloscope 
can detect the Sine waveform, but sometime this waveform will missing and 
come again! So suspect this Y1 crystal (12MHz) is failure and tries to replace it 
with a new one. But TV problem still the same and no change!

The Main board CPU Reset Circuit and the Crystal 
 
To checking the DDR Ram, normally just to measure their Vdd voltage input 
and the Vref (Reference Voltage) voltage. This Vref voltage is about 0.9V, it is 
using the input voltage Vdd (1.8V) divided by two. Also check their control 
signals and the clock signals in between to CPU there. These Control signals are: 
RAS, CAS, WE and CS. The Clock signal like: CK & CKE. Make sure these 
signals are reach to the CPU there. Sometime these signals will break in half 
way. This is because of the PCB circuit hole causing the signal line broken and 
these signals can’t communicate with the CPU. After checking all these signals 
and the voltage inputs, all are normal.

This Main board using Qimonda HYB18TC1G160C2F-2.5 DDR RAM 
 
Since the above steps can’t find out what’s wrong in this Main board, so just try 
to using the ISP Programmer to re-program their Flash Memory firmware. 
Remember, the firmware MUST find out the correct version and suitable for the 
LCD Panel. One more thing, before re-program the Flash Memory, I highly 
recommend to backup their old firmware first before replace it with the new one. 
Finally found the correct version and same LCD Panel firmware to this Main 
board. The result is “still same problem”! 
The last remaining is replacing the DDR Ram, CPU or just replaces a new Main 
board. Suddenly think of the supply voltage to CPU core power and the DDR 
Ram if their Ripple Voltage higher than 10mV will cause the Main board not 
working or working abnormal. 
So use a 470uF/16V electrolytic capacitor connect parallel with their CPU core 
power DC-DC voltage output (U25) there, but the problem still persist. And 
then use a 220uF/16V capacitor connect it with their U3 LDO voltage output to

DDR Ram, suddenly the problem gone and the TV can show the display 
perfectly! Wow, just a cap can solved this TV problem. 
 
Uses the capacitance meter to testing CA103 and CA105 both capacitance and 
ESR values are normal. The other ceramic capacitors all looks like good. So 
decide to replace the CA105 with a 220uF/16V electrolytic capacitor into it. 
Finally this TV problem solved! 
 
Conclusion: 
Starting now, when repair the TV Main board with strange problem, first step 
try to checking their LDO and DC-DC voltage outputs. If all voltage outputs 
normal and stable, then directly add the electrolytic capacitor into the voltage 
input of CPU core power, DDR Ram and the Flash Memory. It will save your 
time and the money too!

without any problem. When the TV auto shutdown, after a while it will auto 
power on the TV and till the display show SANYO logo then auto shutdown 
again! When the problems occur, it will non-stop to shutdown and then auto 
power on again. But some time it can work properly! 
Repair/Solution: 
Even try the repair tip procedure on (1) above, still can’t find any problem. 
After that, think about the Main board LDO and DC-DC circuit Ripple Voltage 
issue. So try to add the electrolytic capacitor 220uF/16V to DDR Vcc input line 
and their DDR Vref (Reference Voltage) line. But the problems still same. After 
that, add another 220uF/16V capacitor to CPU core power line, parallel with 
C747, power on the TV and the problem solved!! Replace the C747 capacitor 
with a 470uF/16V cap. This TV even burn test several days, but it still can 
working in good condition. Finally this TV problem was solved.

NOTE: 
For the SHARP LCD/LED TV, some of their TV Main board has a special 
function, when the problem occurs about 5 times (on the TV, but it’s not 
working, after that off and power on again the TV, it will count as two times 
already), their TV Main board will store the error code inside Main board 
memory IC. So even you’re solved the problem like changed the PSU board, 
inverter or lamps, the TV is still not working. The front LED light will flashing 
Red, Green then Red again and non-stop or etc. Unless you change the Main 
board, the TV will work! 
Actually this problem is easy to solve, if you know how to do that. If you don’t 
know, then you will need to replace the Main board. So the solution is just login 
to the Service Mode to clear their “Failure Mode Memory” and then save & exit 
the Service Mode and the TV problem solved. For more details on how to do 
that, you can refer to my LCD TV Repair Tips V2.0 ebook, pages 53. So this is 
an exception case of the Main board problem. Their Main board is ok, just you 
need to know what’s happen into it, and then you can fix it.

How to find a Substitution of SPI Serial 
Flash Memory and EEPROM ICs in 
LCD/LED TV and Monitor 
Nowadays, lots of the LCD/LED TV and Monitor use the memory IC to store 
the data and firmware on their Main board. Besides to using the Programmer to 
send dataor firmware to memory IC, as a TV repairer, most of the times they 
want to replace the EEPROM IC or Flash Memory to make sure that memory 
IC is normal or not. Because of the EEPROM and Flash Memory IC have lots 
of brands and part numbers, so the repairer cannot prepare all type of memory 
IC. 
Actually all electronic component inside the PCB board, it is better to use the 
original part number to replace it. But some time it is difficult to do that, 
especially you don’t have the same part number to replace it. So this 
information is to let you know, how to choose the right memory IC for the Main 
board. 
How to Choose a Substitute EEPROM IC 
 
 
In general for TV & Monitor Main board, if you want to find an equivalent 
EEPROM IC, you can choose the memory size a bit bigger than the original

memory size. For the 24C series EEPROM IC, it can be divided into two: 
24C16 is downward compatibility for replace 24C02, 24C04, 24C08. The 
24C08 can replace 24C04 and 24C02, 24C04 can replace 24C02. But the 24C32 
cannot replace 24C02, 24C04, 24C08 and 24C16. The 24C64 can replace 
24C32. The 24C128 can replace 24C64 and 24C32. Please make sure that it is 
using the same IC packages. Because some different packages, their Vcc input 
voltages will different. For more details, please refer to their own datasheet and 
it is save before replace it. 
Note: 
* EEPROM= Electrically Erasable and Programmable Read-Only Memory 
24C01= 1K bits (128 x 8= 1024 bits) 
24C02= 2K bits (256 x 8= 2048 bits) 
24C04= 4K bits (512 x 8= 4096 bits) 
24C08= 8K bits (1024 x 8= 8192 bits) 
24C16= 16K bits (2048 x 8= 16384 bits) 
And so on….. 
 
 
Can I replace the EEPROM IC with other brands IC? 
Yes, it can replace it. For example, in the Samsung 943 series LCD monitor 
main board, commonly using this EEPROM IC S24CS08A (Seiko Instrument) 
and causing lots of the problem. So you can use the AT24C08A (Atmel) as an 
equivalent. And it can work very well. 
The 24Cxx series EEPROM IC pin7 (WP- Write Protect) have two kinds of 
method to connect it. The EEPROM IC manufacturer like AT (Atmel), ST 
(STMicroelectronic) and BR (ROHM), their EEPROM IC pin7 need to connect 
to the ground to allow data write into the EEPROM memory. The other 
EEPROM IC manufacturer like KOA, KOR and KS, their pin7 is working on

“Active High”, after that the data can write into the EEPROM memory. The 
“Active High” means this pin7 need to connect to 5V with a 6.8Kohm resistor. 
If not, when you wrong replace with this type of EEPROM IC, the TV will not 
save the TV channel or Volume setting & etc. 
 
Philips PCF Series EEPROM IC 
For Philips EEPROM IC, most of their PCF series IC are compatible with 
24Cxx series. For example, they can replace with: 
24C01  PCF8522 
24C02  PCF8582 
24C04  PCF8592 
 
The PCF8522 and PCF8581/PCF8582 their connection for pin7 (WP) are 
different. PCF8522 pin7 need to connect to ground. The PCF8581 and PCF8582 
their pin7 need to connect it as “Active High”. The substitute for this PCF series 
IC also same, choose the bigger size to replace a bit small size memory. For 
example, PCF8582 can replace PCF8581; PCF8598 can replace PCF8594 
EEPROM IC. 
 
Atmel Series EEPROM IC 
Some repairer said they can see any 24Cxx memory IC inside their Main board. 
Especially if the Main board is use the Atmel latest type of EEPROM IC. 
Actually it is using the part number or calls it as marking code. Besides the DIP 
packaging, the EEPRM IC also have other type of packages like the picture

24Cxxx, actually some ATMEL memory IC also have special marking code for 
it. Here is some of the Atmel EEPROM IC part marking code. With this code 
you will know that what part number of this Atmel EEPROM IC.

Conclusion: 
1) If the EEPROM IC damage, the best choice is use an original part number. If 
can’t get it, highly recommend to use same specification part number but 
different brands IC. For example, the original part number is ST24C16, so you 
can use AT24C16 EEPROM IC to replace it. 
2) When find the equivalent EEPROM IC, need to find a memory size bigger 
than the original one. For example, 24C02 can be replaced by 24C04 or 24C08. 
Please make sure not to use too bigger memory size EEPROM IC, sometime it 
could be malfunction or other strange problem will occur. 
3) Some model TV can’t use the bigger memory size or different brands of 
EEPROM IC to replace their original EEPROM IC. Because of this TV Main 
board CPU will detect the memory IC their ID number. If the number is 
different, the CPU will not accept it and the Main board will not operate or 
strange problem will occur. 
4) Some 24W series EEPROM IC their pin7 (WP) connect to MCU, so this type 
of EEPROM IC is highly recommend to use their original part number memory 
IC. 
5) Again, the EEPROM IC brands like AT, ST & BR their pin7 (WP) need to 
connect to ground, so that the data can write into the EEPROM IC memory. For 
the Korea type EEPROM IC, like KOA, KS & KOR their pin7 (WP) must 
connect to Vcc (5V) with a resistor. For example, when the original memory IC 
is the KS EEPROM IC, if replace by the AT or ST EEPROM IC, make sure that 
the pin7 (WP) need to connect it to the ground (GND). If not, the TV will can’t 
save the TV Channel or other setting values. When the original memory IC is 
ST EEPROM IC, if replace by the KS or KOA EEPROM IC, make sure that the 
pin7 (WP) solder a 6.8K ohm resistor and connect it to Vcc (5V). 
6) Lastly, if using different packaging EEPROM IC, make sure that their Vcc 
pin input voltage suitable the original memory IC or cover in the voltage range. 
Also make sure that the pins are same. So recommend to read their IC datasheet 
to compare it first before replace it.

How to Choose a Substitute Serial SPI 
Flash Memory 
The Flash Memory in LCD/LED TV and Monitor Main board,it is use to store 
the firmware and this firmware was using by the MCU (MicroController Unit). 
They are many type of the flash memory use in the Main board. But in this 
chapter, I’m telling you how to choose the right Serial SPI Flash Memory for 
the TV and Monitor Main board. 
Actually this SPI (Serial Peripheral Interface) flash memory, some memory 
manufacturer will call it as Serial Flash Memory, Serial NOR Flash Memory or 
Serial SPI Flash Memory. But in this ebook I call it as “Flash Memory”. All this 
type of memory will use the “25” series as their marking code. 
They are many flash memory manufacturers in the market now. Most of the TV 
and Monitor Main board flash memory manufacturers are: 
- Atmel/ADESTO: AT25xxx, AT25DFxx, AT25Fxx 
- AMIC: A25xxx series 
- CFEON/EON (same company): EN25Bxx, EN25Fxx, EN25Pxx, 
EN25Qxx, EN25Txx 
- Chingis Technology Corp. (PMC): PM25LDxxx, PM25LQxxx, 
PM25LVxxx, PM25WDxx, PM25WQxx 
- GIGADEVICE: GD25Dxx, GD25Qxx 
- Macronix: MX25Lxxx series 
- Microchip: SST25LFxxx, SST25VFxxx 
- Nantronics: N25Sxx 
- Nexflash: NX25Pxx 
- ShangHai Fudan Microelectronics: FM25Fxxx 
- Spansion: S25FLxxx 
- STMicroelectronics: M25Pxx, M25PXxx 
- Trojan: T25Pxx 
- Winbond: W25Pxx, W25Qxx, W25Xxx 
- and etc

When need to replace the Flash Memory IC, the best way is use the original part 
number. But most of the time, it is not available or hard to get the original part 
number flash memory IC. Actually to find the substitute flash memory IC you 
must follow these rules and successfully to replace it. These RULES are: 
1) The Flash Memory need to find the same packages, Vcc input voltage and 
their pins configuration. But most of the time, their pins configuration is same. 
2) Flash Memory Density (space of the memory) must same or bigger than the 
original. For example, if the original flash memory is MX25L1605, this IC 
density is 16Mbit, if you use the EN25T80 to replace it, then the Main board 
will not work. Because of this flash memory EN25T80 density is just 8Mbit 
only. So the Main board firmware is missing half of the data and cause the 
firmware corrupt. So we can use the W25X16 (16Mbit) to replace it. Or use the 
EN25F32, density is 32Mbit also can replace it. Not recommend to use 64Mbit 
or 128Mbit to replace it.

Page 68 
3) If after replaced with the same density flash memory also not works, then 
you may want to consider their original flash memory Read/Write IO type and 
part number problems. Actually the flash memory different to several types, 
commonly is using the Standard SPI series flash memory, Unique ID series, 
Default Lock Protection series and so on. Most of the LCD/LED TV and 
Monitor Main board is using the Standard SPI series flash memory. 
Normally the Standard SPI 25xxx flash memory I/O has one data input and one 
data output; but for example the EON 25B or 25Q is different, the 25B series 
have 2 bidirectional I/O and for the 25Q series have 4 bidirectional I/O 
(EN25Q16 or EN25Q32). So the 25B and 25Q series are suitable to substitute 
the Standard SPI flash memory, but the Standard 25xxx flash memory is not 
suitable to substitute the 25B or 25Q series. If the Main board is using 4 
bidirectional I/O, the EN25B16 cannot substitute the W25Q16, but we can use 
the GD25Q16 to substitute the W25Q16 and so on. 
4) Some TV/Monitor Main board they will recognition the flash memory ID, so 
their firmware will first checking the device ID first before working. So for this 
type of Main board, you need to replace it with the same specification of flash 
memory IC. For example the Macronix MX25xxx08 Unique ID series flash 
memory. 
5) After substitute the flash memory on the Main board, if using the ISP 
programmer to do the in circuit (ISP) Read/Write firmware, some MCU IC like 
NT68 series with external flash memory type, maybe will not recognition the 
new flash memory. This issue is seldom happen, but it happened too. 
One more thing, highly recommend to read the original and substitute flash 
memory specification datasheet first before replace it. So that you can make 
sure their pins configuration and the Vcc voltage input are same. And other 
information like the type of flash memory for original and the substitute flash 
memory.

What is LED Driver in LED TV? 
The LED Driver in old LED TV service manual will call it as “inverter”, LED 
inverter & etc. But the latest LED TV service manual or training manual will 
call it as “LED Driver” board now. 
This LED Driver function like the LCD Inverter board, where the voltage input 
is low or small but output voltage is high. For example the LCD TV inverter 
input 24Vdc, but their output is about 1500VAC (depends on the inverter board 
design). For the LED Driver, its input 12Vdc (Vcc input for small inches LED 
TV) or 24Vdc and the output voltage is about 57Vdc, 120Vdc, 200Vdc and etc. 
But some of the small sizes LED TV (19, 22, 24 inches & etc) will direct 
generate voltage like 33V, 42V, 44V & etc, from the PSU secondary side 
supply to the LED strips/bars. This type of design, their brightness is cannot be 
adjust. Also some of them can’t control the backlight on/off, when TV power on, 
the LED backlight is automatically on. 
So the LED Driver board/section their function is use to boost up the low 
voltage (DC voltage) and output to higher voltage (DC voltage). And it also 
included the typical features like backlight On/Off, Brightness control, circuit 
protection and etc. 
 
The Advantages of LED TV vs LCD TV 
Actually the LED TV has lots of the advantage when compare with LCD TV 
(CCFL or EEFL backlight). For example: energy saving save space (so the LED 
TV can manufacture more thinly than the LCD TV and etc. Some of the repairer 
will surprisingly why the latest 32 inches LED TV their Power Supply not 
included the PFC circuit in it! Because of the 32 inch LED TV their power 
consumption is below 85Watts or 70 Watts. For international standard, if the 
TV power consumption is 70 Watts or below it (China is below 85 Watts), their 
Power Supply (PSU) no need to built-in the PFC circuit in it. 
That’s why lots of the latest 32 inches LED TV their selling price is so cheap. 
One of the reasons is, their PSU no need to built-in the PFC circuit and save the 
cost. It is because of the latest 32 inches LED TV their power consumption is 
just about 45Watts ~ 80Watts only.

Most of the signal lines from Main board to LED Driver board/section are same 
as the LCD TV inverter. But some of them maybe their marking name/code in 
PCB board is different. For example the BL_ON signal, in some LED Driver it 
will show as DRV_ON, BLU_ON & etc. But their feature is the same, just to 
switch on the backlight system. 
For the P-DIM (Digital Dimming) signal in LED Driver, it is a bit different than 
the LCD TV. Some LED Driver board P-DIM signal is call it as PWM, 
PWM_DIM and etc. Where the LED Driver P-DIM (or similar name of it)

signal voltage range is about 0~5V (LG LED TV is about 0.2V~3.3V, Samsung 
LED TV is about 0.5V~4V). This signal is use to control the Brightness levels 
for backlight system. When the LED TV is Maximum (MAX) brightness, its P-
DIM signal voltage is about 5V, for Minimum (MIN) brightness of LED TV, it 
is about 0V. So the P-DIM signal functions like backlight dim control. 
 
A Tip to Check the LED Panel 
If the LED TV left and right side has abnormal brightness or one side is 
darkness but another side is ok, then you can use this tip to checking the LED 
Panel. 
 
When you see the screen in front of TV, if a left side (a) has a problem, connect 
(2) cable at the (1) position and see the display result. If after changed cable 
position the TV (a) side has normal picture now, that’s mean their LED Panel is 
ok (LED Blocks/Strips are normal), problem was in their LED Driver section. If 
after changed cable position, the TV side (a) still shows abnormal picture, for 
example darkness picture, that’s mean their LED Panel side (a) LED blocks was 
defective and need to checking or replace it.

LED Backlight Repair Tips for LED TV 
Nowadays, lots of LED TV and LED Monitor are come to the work bench now. 
Most of the time LED TV display darkness problem is causing by the LED 
Driver board detected some abnormal status in LED strips/bars and shutdowns 
the LED backlight system. If the LED Driver not shutdown the backlight, it will 
show as one of screen position is darkness (top, bottom, left or right side). 
Normally this type of problem is causing by one LED light bulb opens in a LED 
strip/bar or block. So it will affect the other LED light cannot work. After that 
the LED Driver will shutdown the LED backlight or that.

How to Bypass LCD TV Inverter Board 
Shutdown Backlight System- Inverter IC 
List 
SAFETY FIRST! 
 If you’re not understand about how to testingthe electronic components, 
please DON’T read this chapter. 
 Please make sure that the Inverter board are no any components is shorted 
or leakage, if not it will burn Inverter board again. 
 Again, this bypass method is just for troubleshoot the Inverter Board for 
components level repair and it is NOT to repair the Inverter Board. If 
you’re bypassing the Inverter Board protection in this way, it may occur 
the fire in Inverter Board and the TV. Because when happen heavy 
shorted in the Inverter Board, it will not start-up the protection and 
causing the Inverter Board burn and TV maybe explode too! 
 
This method also calls it as: ‘How to Bypass LCD TV Inverter OVP Protection’. 
I had one article mention it before at: 
http://www.lcd-television-Repair.com/Bypass-Inverter-OVP-Protection.html 
Most of the time, we will feel headache when we repair LCD TV with symptom 
display shutdown after few seconds, but they have normal sound. And 
sometime, you can use the strong flash light to see some content in the screen 
there. So it will confirm that the problem was in the backlight system (inverter 
board/section and their CCFL lamps). 
Before checking the backlight system, make sure that BL_ON/INV_ON signal 
(backlight on signal) and PDIM/DIM/ADJ (brightness control signal) are 
appears in the Inverter board/section. These both signals are come from the TV 
Main board and their normal voltage should be: BL_ON= 2.5V~5V and the 
ADJ= 0.8V~5V (5V is maximum brightness in the screen). Also you need to 
measure the voltage supply (Vcc) to inverter board is normal and stable; 
normally it is 24V or 12V.

So with the above information, if all signals and voltage appears, we can know 
that this TV Display shutdown problem is in the inverter section or their CCFL 
lamp/s. For the CCFL lamp problem, normally it is leakage, broken or their wire 
contact with the lamp terminal has open. When checking the CCFL lamp, you 
need to open the lcd panel. But make sure to carefully remove their metal shield 
and other parts to prevent any damage on the lcd panel glass, especially their 
COF/TAB. 
For the inverter board/section, after checking all the suspicion components in it 
and still can’t find any damage components then you will not sure what’s the 
next step to check. 
So this chapter is to let you learn the method on different inverter IC for how to 
bypass their OVP Protection, so that we can see and check their inverter board 
and the lamps. 
Before using this method to testing the Inverter board and their CCFL 
lamps, make sure the Inverter board no any shorted or leakage 
components in it. This is a very important step to prevent any burn or 
explode in the board. 
When the TV is shutdown the backlight after few seconds, with the help of 
bypass Inverter IC protection, we can check the Inverter board in components 
level repair. After bypass the inverter IC OVP protection, these will happen in 
the TV: 
a) The backlight is lit now but we can see one of these CCFL lamp is off or 
weakness. 
 * That’s meant this CCFL lamp is damage and need to replace. Before 
replace, first check their both side of wire terminal connection is solder ok or 
not. If not then re-solder it and try to power on the backlight to see the problem 
solved or not, if not then just replace it with a working one. We can use the 
CCFL Lamp Tester to testing this lamp to confirm it is ok or not. 
 * If the lamp is ok but this lamp still not lit, that’s mean this CCFL lamp 
their circuit is abnormal, so that we can concentrate and quickly checking on 
this CCFL lamp circuit to find out what’s wrong in it. 
b) If the TV backlight still shutdown after bypass their inverter protection.

 * This problem is because of the Inverter board has shorted or leakage 
component/s in the board. So that you need to confirm the components in 
Inverter board is not shorted or leakage. 
* Or the inverter IC pin is wrong to do the bypass protection and make 
sure to put the correct pin number of the inverter IC. 
 
This Inverter IC list is use to bypass the inverter board/section to shutdown their 
backlight system. For your information, before using it, make sure they are no 
any shorted or leakage components in the Inverter board or section there.

The Method of How to Find LCD & LED 
TV Panel/Screen as a Replacement or 
Equivalent 
 
When I’m doing the email support for my members, I’m receiving lots of 
question about “How can I replace the LCD Panel with different part number”? 
The reason to replace it was because the LCD Panel is broken or damage. My 
answer to them is “YES” it can be replaced! But their question is how can I 
replace it? 
Normally I will not recommend this method to the TV repairers who are: 
1) Don’t have extra good or working LCD Panel in hand. 
2) Don’t know how to Self Test the PSU board + Backlight without connect it 
to Main Board. (This method was wrote in V3.0- 
http://www.lcdrepairguide.com/V3 ) 
3) Don’t know how to testing the voltage and signals in Main board, PSU board, 
Inverter Board and the T-Con board. 
In this chapter, I will let you know how to find a replacement for LVDS type 
LCD Panel. Actually the LCD Panel has two types, one is TTL (old model LCD 
TV) and another is LVDS type (Low Voltage Differential Signaling). But in this 
chapter I just show you how to choose the LVDS type LCD Panel as a 
replacement. 
 
Basic Knowledge of LCD Panel 
The LCD TV Panel has different types, but in this chapter I just reveal the 
LVDS type LCD & LED Panel. The important information we need to know for 
LCD Panel are: 
1) Screen Size: 
 * The LCD screen have many sizes, common use in Monitor & TV are 
15~65 inches. But it also divides to different aspect ratio (DAR), they are: 
standard screen (4:3) and wide screen (16:9 or 16:10). 
http://www.lcdrepairguide.com/V3
SHAVICTypewritten text
ImagineX ElectronicS
COLLECTION OF LCD/LED TELEVISION REPAIR TIPS-V4.0 
 
Page 90 
2) Resolution: 
 * LCD Panel resolutions are often quoted in terms of raw subpixels, 
misnamed “pixels” in manufacturer’s specifications. Each real pixel includes 
one subpixels for each of three colors, so calling subpixels “pixels” inflates the 
claimed resolution by a factor of three. This bit of marketing obfuscation is 
calculated as horizontal resolution x vertical resolution x 3(HxVx3). For 
example: 1024 x768 x3= 2359296 subpixels, but only 786432 full-color pixels. 
The LCD TV Panel have different resolution, they are: 
 Standard Definition (SD): 1366 x 768, 50Hz/60Hz, 2 Channels/Ports 
 High Definition (HD): 1920 x 1080, 50Hz/ 60Hz, 4 Channels/Ports 
 Full HD TV (FHD TV): 1920 x 1080, 100Hz/ 120Hz, 8 Channels/Ports 
 Ultra HD (UHD): 3840 x 2160, 60Hz, 16 Channels/Ports 
 And etc…… 
3) Bits: 
 * The Color Depth or Color Support is sometimes expressed in ‘Bits’, 
either as the number of bits per sub-pixel or the number of bits per pixel. The 
LCD TV Panel has divides to 6 bits, 8 bits and 10 bits. Also have different 
channels for each bits, for example, 8 bits 2 channels (LVDS interface), 10 bits 
4 channels and etc. 
4) Input Voltage: 
 * Normally the LCD TV Panel input voltage (actually is the T-con board 
Vcc input voltage) is using 5V or 12V, but some special part number of LCD 
Panel will use 18V too. For the small inches LCD Panel, it will use 5V or 3.3V 
as their Panel Vcc input voltage. 
5) LVDS pins Description & Connector types 
 * The LVDS pins description we can refer to their LCD Panel datasheet 
or product specification manual. 
 * The LVDS interface has many types of connector design & number of 
pins. Normally it has 20 pins, 30 pins, 41pins, 51 pins and etc.

Please refer to the Bonuses Section B Download Page to download the LCD 
Panel datasheet. Inside the datasheet you can find lots of useful information to 
help you to replace the LCD Panel correctly. 
 
The Methods to Find a Replacement of LCD & LED Panel 
If you want to successfully replace the LCD Panel, you must follow and check 
these information below before replace it: 
1) LCD Panel input voltage (Important step and make sure the voltage input is 
same) 
 * If the input voltage not same it will damage the T-CON board or/and 
LCD Panel! If LCD Panel is 12V type the Main board is supply 5V to it, the 
LCD Panel will not working only. If LCD Panel is 5V type but the Main board 
is supply 12V to it, the LCD Panel will damage or the T-CON board burn or 
both also gone. 
 * Actually the LCD Panel voltage input type is depending on the T-CON 
board Vcc input, except the T-con board is built-in the LCD Panel. 
 * Some repairer if they know how to use the DC-DC module, they can 
use it and put it in the T-CON board Vcc input and modify it. For example the 
DC-DC module like 12V to 5V output, but make sure their Ampere is match 
with the LCD Panel. For your information, some of the Main board is already 
built-in 12V and 5V Panel select jumper to choose. So this type of Main board 
can save the time and money to match the new LCD Panel. 
2) LVDS connector type and LVDS pins configuration 
 * Make sure to check the original and replacement lcd panel pins 
configuration from their panel datasheet. For the LVDS connector type we can 
use the eyes to look at it. If the LVDS connector type is different than the 
replacement LCD Panel, so need to find or buy a suitable LVDS cable with the 
same connector type. If their pins configuration is different, some LVDS cable 
can manually change or correct their pins position to the right position. For this 
step, we must refer to their LCD Panel datasheet to do it correctly. 
 * Attention: Make sure their Vcc Voltage Input pin is put in the correct 
position, if not it will damage the LCD Panel!!

3) LVDS Interface 
 * LVDS interface format is divides to two: 
 a) JEIDA Format 
b) VESA Format 
It is control by the SELLVDS or LVDS_SEL signal pin. Normally 
different LCD Panel manufacturer they have different method to setting it. For 
example, CHIMEI V315H3-LS2 LCD Panel, their JEIDA format is set 
SELLVDS to ‘L’ (active Low) and VESA format is set SELLVDS to ‘H’ 
(active High) or Open. To set this signal pin you can do like that: 
a) Active Low ‘L’ = Short this pin to Ground. 
b) Active High ‘H’= Connect this pin to Main board 3.3V supply. 
c) Open = Remove this SELLVDS wire pin from the LVDS connector or 
Main board side connector. 
If this SELLVDS signal pin set it incorrectly, the TV display will show 
display distortion symptom or their display show reverse 180 degree. 
 
4) ‘Bits’ select for the LCD Panel 
 * Most of the time, the LCD TV Panel is using 8 bits type. Some high 
definition LCD Panel is using the 10 bits type. The 10 bits type LCD Panel 
divides to two: 
 a) The ‘Bits’ cannot be select, only can working in 10 bits status. This 
type of LCD Panel cannot choose as a replacement for 8 bits type LCD Panel. 
 b) The ‘Bits’ is selectable by setting the signal pin in LVDS interface. As 
usual, it is set by Active Low, Active High or Open. So this type of LCD Panel 
can choose to working in 8 bits or 10 bits status. So this type of LCD Panel can 
use to choose as a replacement for 8 bits type LCD Panel. 
 * If the 10 bits LCD Panel is use as a replacement of 8 bits LCD Panel 
and their display quality was not good and have some noise in the screen, please

double check their “Bit” select control signal pin/s is set to the correct position 
(L, H or Open). 
5) Backlight System 
 * The backlight system has many types. If it is LCD type, they will use 
the CCFL or EEFL lamps. If the LED type, it is using the LED light bulbs with 
different voltage control in LED Driver. 
 a) EEFL type: If the LCD Panel is using these EEFL lamps, then it is easy 
to replace their LCD Panel. Because it just use two connector or wire in their 
inverter board only. Most of their connector design is same, so it will let the 
repairer easy to replace it. 
 b) CCFL type: If their replacement LCD Panel is using Single inverter 
board but original LCD Panel has Master and Slave inverter board, so their 
extra wires can bypass it. But make sure all the voltage cable, signals cables are 
connecting correctly. If the replacement LCD Panel is using master and slave 
inverter board but original LCD panel just has single inverter board, then you 
need to modify it and connect the extra cables to their slave inverter board there. 
Make sure their voltage supply and signals cables connecting correctly. 
 * For LED type: Use their replacement LED Panel LED Driver board and 
make sure their voltage and signals cables are connecting correctly. If that is IP 
board type LED driver, then you need to make sure their output voltages is 
match the LED Panel, if not it will not work or maybe will damage the LED 
light bulbs or this LED Panel will not lasting long time use. 
 * For more details in their control signals, please refer to the V3.0 LED 
LCD TV Repair Tips ebook. 
 
6) LCD Panel Parameters 
 * If these LCD Panel parameters not same, so this LCD Panel cannot be a 
replacement. 
 a) LCD Panel Resolution not same, it is can’t be a replacement. 
 b) LCD Panel size not same, it is can’t be a replacement. For example 32 
inches is use the 32 inches LCD Panel as a replacement. The 31.5 inches cannot

use the 32inches LCD Panel as a replacement. Also their aspect ratio (DAR) 
must choose it correctly and it is divides to: 4:3, 16:9 or etc. 
 * One more thing, some LCD Panel their thickness is different. If the 
original LCD Panel is thicker than the replacement, it is ok to replace. Because 
the TV cover can close it perfectly. But if the original is thin than the 
replacement, it is hard to say ok or not. Make sure the TV rear cover can close it 
perfectly, if not, then it is not recommend to replace it.

Remark: 
The above charts just for reference only and you must follow the “The Methods 
to Find a Replacement of LCD & LED Panel”. So you can find the correct LCD 
Panel to replace. One more thing, inside the 32 inches chart, the 320 is for 32 
inches and the 315 is for 31.5 inches. So some of the LCD they will not match 
to replace, because the original TV Main board will not send out the correct 
LVDS format signal to it. But some LCD Panel like AUO T320XVN02-A, it is 
31.5 inches type not the 32 inches. So it is suggest referring to their datasheet 
for more details. 
Another thing is their Panel voltage input (Vcc). Besides the 5V and 12V, some 
part number of LCD Panel have different Vcc input, for example the CMO 
V420H1-L01 it is using the 18V. So be careful about it, if not it will damage the 
LCD Panel again.

The T-CON Board 
Nowadays, the LCD LED Panel Timing Control section is not only in the T-
CON board, but it also built-in the LCD Panel and the Main board. The Timing 
Control section and their DC-DC circuit have higher repair rate in LCD LED 
TV. If the T-CON was built-in the LCD/LED Panel, then lots of TV repairer 
will direct return the TV to customer and told them this TV is beyond repair or 
not worth to repair it, because it is the LCD Panel problem.

Actually the small sizes LCD/LED Panel, their Timing Control and the DC-DC

basic knowledge of T-Con Board, please refer to the V3.0 ebook for more 
details. 
If we know how the T-con board work and also know how to troubleshoot it, 
then it will help us to repair the T-con board or LCD Panel easily. Another 
problem to repair the T-con board/section is their spare parts. So we can search 
the parts online or find the part in the junk T-con boards.

The Importance of Checking GAMMA & Vcom Voltage 
in T-CON Board 
If you’re repair LCD or LED TV, or even the LCD/LED Monitor, the Timing 
Control section is important and we must figure out how it work and how to 
troubleshoot it. Some repairer will say the T-CON board is cheap to replace, so 
no need to learn more about it. 
But the problem is not all LCD/LED TV and Monitor are using the T-CON 
board, especially the LCD/LED Monitor and Laptop LCD/LED Panel their 
Timing Control section are built inside the Panel or call it as LCD Controller. 
I found that lots of the LCD/LED Monitor and Laptop Panel/Screen problem 
can be repair but lots of the repairers just throw away it into the rubbish. And 
then replace a new Panel or just return back the Monitor to customer and say 
beyond repair or not worth to repair. 
So we must learn how the T-CON work and the method to troubleshoot it. No 
wonder the Timing Control section is design inside the Panel, T-CON Board or 
Main Board, so that we know how it works and where to checking their circuit. 
 
How the GAMMA channels voltages and VCOM voltages 
generated? 
When the T-CON board (for example V315B3-C01 T-con board) DC-DC 
circuit generated the VDA voltage, this voltage is use to generate the GAMMA 
and VCOM voltages through U6 (HX8915A). This HX8915A is a 14+1 
channels buffer IC, the ‘14’ is for 14 x GAMMA channels and another ‘1’ is for 
1 x VCM channel use. 
This VDA voltage will go to: 
 
1) VDA voltage go through the R335 resistor to generate the VDA_OP voltage 
for GAMMA IC U6 (HX8915-A, similar with the AS15 series IC) Vcc input 
use. 
SHAVIC

Page 106 
 
2) The VDA voltage also goes to D1 & D4 to generate the VREF (Voltage 
Reference) voltage and send it to their voltage divider resistor circuits. 
 
 
Normally the VREF circuit just uses the D1 (KA431 type component) to 
generated VREF voltage only. This VREF voltage normally is about 12.5V. But 
different design it has a bit different on it. 
 
3) For this T-CON board V315B3-C01, the VDA voltage also sends to U2 to 
generate the VSCM voltage and then send to U6 to generate the VCM (Vcom) 
voltage. Normally this VCM voltage is generated by the VREF circuit. The 
VREF output line go through two resistors as voltage divider resistor circuit and 
get the VSCM voltage, and then send it to U6 (HX8915A) to output the VCM 
(Vcom) voltage. This Vcom voltage will send to the LCD Panel glass.

Page 107 
 
 
Note: 
The Vcom (VCM, Common Voltage) voltage is about half of the VREF voltage. 
Remember this rules, the VCM voltage is about half of the VREF voltage. If the 
Vcom voltage not stable or their voltage is out from the original values, the TV 
display will abnormal or their brightness problem. 
 
After the VREF voltage was generated, it will send to 2 groups of resistors 
voltage dividing circuits. These 2 groups of resistors voltage divider resistor 
circuits will divided the VREF voltage to 14 channels different voltages call it 
as VS1~VS14 GAMMA voltages. But these voltages can’t direct send to the 
LCD Panel use, they need to send it to the buffer IC U6 (HX8915A or AS15 IC), 
and then it will output the GAMMA voltages GM1~GM14. These GAMMA 
voltages will send to the LCD Panel Source Driver board.

What will happen when Vcom (Common Voltage) voltage 
missing? 
When the Vcom (VCM) voltage is missing, the Panel display will become white 
and it is looks like the negative picture. If this is happen to your TV, you need 
to check their output voltage at the T-CON board. Normally their marking code 
at PCB board is “Vcom”, “VCM” or etc. If you’re not sure what voltage values 
is normal for the Vcom, never mind, do you remember the Vcom voltage is 
about half of the VREF voltage. So you can find the VREF voltage to measure 
it and then you can roughly know what the voltage values for the Vcom voltage 
are.

How to know the GAMMA channels voltages normal or 
abnormal? 
As you know that the GAMMA channels voltages when different T-con board 
or Panel, it has different channels in it. Normally is about 14 channels, 18 
channels or above 20 channels. But all these GAMMA channels voltages has 
one important rules, that is “ The GAMMA Channels Voltage their voltages 
order is from high to low or low to high”! 
For example good GAMMA Voltages from high to low (V315B3-C01T-CON): 
CM1- 15.17V CM8- 6.27V 
CM2- 14.16V CM9- 5.99V 
CM3- 11.99V CM10- 5.20V 
CM4- 11.40V CM11- 4.26V 
CM5-10.67V CM12- 3.36V 
CM6- 9.88V CM13- 1.35V 
CM7- 8.21V CM14- 0.73V 
Their voltages order high to low will looks like this: 
15.17V, 14.16V, 11.99V, 11.40V, 10.67V, 9.88V, 8.21V, 6.27V, 5.99V, 5.20V, 
4.26V, 3.36V, 1.35V, 0.73V

COLLECTION OF LCD/LED TELEVISION REPAIR TIPS-V4.0 
 
Page 111 
If you found the GAMMA Channel Voltages like these, that’s mean the 
GAMMA circuit is failure and you need to check it. If not find any components 
failure, just try to replace their buffer IC like AS15, HX8915A & etc. 
The Example of Bad GAMMA Voltages: 
1) 11.5V, 10V, 8V, 3V, 7.06V, 6.75V, 6.03V, 5.73V, 4.88V, 4.02V, 3.66V, 
2.81V, 1.35V, 0.53V 
2) 0.78V, 1.45V, 2.28V, 3.88V, 4.34V, 5.02V, 5.78V, 6.67V, 9.23V, 8.95V, 
8.55V, 9.46V, 10.78V, 12.3V 
3) 15.02V, 14.52V, 11.38V, 10.01V, 9.47V, 8.95V, 8.03V, 7.55V, 6.68V, 
5.62V, 4.03V, 2.76V, 5.13V, 0.68V 
You can check the GAMMA voltages on the T-CON board and their marking 
code is GM, CM, PGM or etc. 
 
 
Besides the DC-DC circuit has higher failure rate in T-Con board, the second is 
the GAMMA circuit. So if the GAMMA voltages abnormal, it will cause the 
TV display color abnormal, display noise in the display background or etc.

Why After Replaced the AS15-G IC to AS15-HG The TV 
Still Has Problem? 
The AS15 series IC is a 15 x Op Amp IC. It is 14 + 1 Op-Amp, 14 Op-Amp is 
for the GAMMA use and another one is for VCOM. Some TV repairer said 
after replace the AS15-HF to AS15-HG, the TV screen problem not solve or 
more serious than before. Sometime after replace the AS15 IC, the TV display 
is ok about 20 minutes, then whole screen change to nearly white screen about 
3~5 seconds, and then screen back to normal about 5 minutes and then changed 
to white screen again. So the screen is non-stop to change like that, and the new 
replace AS15 IC can feeling extremely heat. Are the AS15G and AS15HG 
compatible? But when change to another batch of AS15 IC, the T-Con board 
problem solved! 
 
 
Actually the AS15F, AS15G, AS15-HF & AS15-HG all are compatible and 
equivalent to use! But the problem is lots of the AS15 series IC in the market 
now is not in good condition or call is as recon IC. Especially the cheapest price 
of AS15 IC, this type of IC mostly has higher chances is not a good IC.

The above picture of AS15-F IC, this batch of IC: 0452A, we found that after 
change to this IC, the IC is extremely heat on the T-con. Finally found the 
AS15-HG IC batch no: 1032B, after replace AS15-F with this AS15-HG, the 
TV display problem solved and the IC temperature is just feeling warm only. 
Even the AS15-HG batch no: 1210C also not good to use. 
Note: 
I have a tip for this AS15 series IC or even the AS19 series also same. When 
they replace the equivalent or compatible AS15 IC on the T-con board, if the 
finger can feel AS15 IC surface is very hot, but the display is ok, then I will 
recommend change another AS15 IC. Because it will cause this T-con board 
cannot last long to use. Or the AS15 IC is extremely heat on the IC surface and 
their TV display also abnormal, then direct removes it and replaces another one 
to try again. So lots of the TV repairer if they facing this problem before, 
hopefully they know what can do now and don’t confuse about it again.

Symptom: Display Color Problem like Oil Painting and the Display also 
Reverse 180 degree now. 
 
 
Repair/Solution: 
Regarding this type of symptoms, lots of the TV repairer will give up to repair it. 
Because they will think it is their LED Panel (or T-CON Board) problem. Also 
this TV is a fake Samsung 43 inches LED TV, their repair information is hard to 
find to compare to the original TV manufacturer. 
So this TV is send by another TV Repairer and he also said if can’t repair it 
doesn’t matter, because it is not the original Samsung LED TV. This TV cover 
is looking like Samsung, but inside the TV, it is just using an OEM brand TV 
Main board only.

After analysis this LED TV symptoms, I suspect it was the T-CON board or 
Main board problem. Why I’m not suspecting the LED Panel? Because I know 
that the display reverse problem is causing by their SELLVDS or Rotation 
signal set as incorrect by Main board or the T-con board problem. 
Before starting to repair this LED TV, I will checking their Service Mode 
setting or just try to do the firmware upgrade for it. But the problem is, this is 
not the branded TV, so we don’t have the enough information to find their 
service manual and then know how to login to their Service Mode. Also we 
don’t have this Main board good firmware to do the upgrade too. 
So what can I do now? Actually for this type of OEM TV Main board, they 
have the part number in the Main board there. Finally found the Main board part 
number: TSUMV59UXS_V1.1 as picture below:

Found the information for this Main board. This is a ROWA V59 series Main 
board and its Service Mode login step is using the remote control: 
 a) Press MENU, the screen is showed the Menu OSD there 
 b) Press number buttons: 1147 and the screen will show another OSD 
Menu 
 c) Select: General, Setting, Login 
 d) Select LVDS MAP adjust 1, 2, 3, 4……16 after adjusted ok, press the

LED39K321 LED TV 
Symptom: The TV is White Screen Problem 
The TV is White Screen problem, but the sound is normal. This LED TV is 
using the CMI V390HK1-LS5 LED Panel and their T-CON board part number 
is V236H3-CS3-C.

Symptom: Display Distortion Problem 
 
 
 
Repair/Solution: 
After dismantle this LCD TV and found that their Timing Control is built-in the 
Main board there. When checking the Main board and saw that their GAMMA 
IC is using this AS15-G IC, so measure their GAMMA output voltage. Found 
that one of their GAMMA voltage output was abnormally. So direct replace this 
AS15-G IC with this AS15-F and the TV problem solved!

5) Model: Sharp LCD32WXN LCD TV 
Symptom: Negative Display 
The screen brightness is high and the display no gray scale in it. 
 
 
Repair/Solution: 
After analysis the picture above and found that this type of symptom is causing 
by the T-CON board. The screen is just show negative display only and no any 
gray scale for the picture. Most of the time, this type of problem also cause by 
their T-con Board GAMMA or Vcom circuit. 
This LCD TV T-con section was built- in the LCD Panel, so need to remove 
their metal bracket to checking their T-con section. First check the VDD_R has 
14.9V, after that checking the VR_VCOM has 0V! So this voltage values is 
abnormal for the VCOM voltage, because the Vcom voltage normally is about 
half of the VDA voltage. Measure the VR1 pin 1 (one of the R276 pin), its 
voltage still 0V, so suspect the VR1 is open circuit. Remove the VR1 (marking 
as ‘23’) and using the Multimeter measure it and found the VR1 was opened 
circuit.

VCOM Voltage Circuit 
Since the VR1 is marking as’23’, that’s mean their ohm values is 2K ohm. 
Because of the VR1 center pin position is in the middle, that’s mean, the ohm 
values is about 1K ohm (half of the 2K ohm). So you can replace a 1K ohm 
resistor to VR1 pin2 & pin3, but make sure the VR1 position pin1 & 2 is 
shorted. After replace the VR1, VR_VCOM has output 7.54V there and the TV 
problem was solved.

Repair/Solution: 
Actually this type of symptom is we can repair it through: 
a) Software control: Some TV is allowed to login to the Service Mode and 
change their setting to cure this problem. 
b) Hardware modify: If the TV not provide the software control, then we can 
modify the hardware, especially the T-CON board LVDS connector pin27 & 28.

Note: If a particular area is exhibiting a dimmer backlight level than other areas or 
the overall brightness seems dim, be sure to first check the customer’s Menu 
setting for Backlights. Raise the percentage and see if the overall brightness returns 
to normal. If not, 
1st: Check the P-DIM level, it should rise with the percentage shown on screen. 
100%, 3.3V. Follow the P-DIM signal all the way to the Inverter. 
2nd: Turn off Local Dimming in the Customers Menu. If the brightness returns to 
normal, examine the signals required for Local Dimming. 
(SIN, V-SYNC and SCLK).
SMPS TEST 1: Force Power Supply On.
Disconnect P502 on Main board.
(A) Jump pins 9, 10, 11 or 12 (3.5V) to pin 1. 
Test Voltage Outputs 12V, 24V to Main and 
36V to the Inverter Section of the SMPS. 
Remove AC power. Leave the jumper in place.
SMPS TEST 2: Force the Backlights On.
(B) Jump pins 9, 10, 11 or 12 (3.5V) to pin 18 
(DRV-ON). Apply AC power, the Backlights 
should turn on. Note, the LED B+ will now jump 
to 65V then back down to 45V.
Note; If there is a problem with a load from the 
panel backlights, you can remove AC and 
Disconnect P202 or P203. When AC is 
reapplied, the Backlight LEDs should turn on 
for about 4 seconds and then shut off.

Note: If a particular area is exhibiting a dimmer backlight level than other areas or the 
overall brightness seems dim, be sure to first check the customer’s Menu setting for 
Backlights. Raise the percentage and see if the overall brightness returns to normal. 
If not, 
1st: Check the P-DIM level, it should rise with the percentage shown on screen. 100%, 
 2.91V. Follow the P-DIM signal all the way to the Inverter. 
2nd: Turn off Local Dimming in the Customers Menu or unplug P701 (with power off). 
 If the brightness returns to normal, examine the signals required for Local 
 Dimming. (SIN, V-SYNC and SCLK). Suspect the Main Board.
SMPS TEST 1: Force Power 
Supply On.
Disconnect P2400 on Main board.
(A) Jump pins 9, 10, 11 or 12 
(3.5V) to pin 1. Test Voltage 
Outputs 12V, 24V to Main and 
60V to Backlights reads 36V. No 
Backlights. Remove AC power. 
Leave the jumper in place.
SMPS TEST 2: Force the 
Backlights On.
(B) Jump pins 9, 10, 11 or 12 
(3.5V) to pin 18 (DRV-ON). Apply 
AC power, the Backlights should 
turn on. Note, the LED B+ will now 
jump up to 61V.

Note: If a particular area is exhibiting a dimmer backlight level than other areas or 
the overall brightness seems dim, be sure to first check the customer’s Menu 
setting for Backlights. Raise the percentage and see if the overall brightness returns 
to normal. If not, 
1st: Check the P-DIM level, it should rise with the percentage shown on screen. 
100%, 3.3V. Follow the P-DIM signal all the way to the Inverter. 
2nd: Turn off Local Dimming in the Customers Menu or unplug P832. 
If the brightness returns to normal, examine the signals required for Local Dimming.(SIN, V-SYNC and SCLK). Suspect the Main Board.
SMPS TEST 1: Force Power Supply On.
Disconnect P502 on Main board.
(A) Jump pins 9, 10, 11 or 12 (3.5V) to pin 1. 
Test Voltage Outputs 12V, 24V to Main and 
36V to the Inverter Section of the SMPS. 
Remove AC power. Leave the jumper in place.
No Backlights. 50V to Backlights reads 36V.
SMPS TEST 2: Force the Backlights On.
(B) Jump pins 9, 10, 11 or 12 (3.5V) to pin 18 
(DRV-ON). Apply AC power, the Backlights 
should turn on. Note, the LED B+ will now jump 
to 65V then back down to 50V.
Note; If there is a problem with a load from the 
panel backlights, you can remove AC and 
Disconnect P202 or P203. When AC is 
reapplied, the Backlight LEDs should turn on 
for about 4 seconds and then shut off.

Error line:
If the error line goes 
high (3.4V) the back-
lights will shut off. 
142V will drop to 116V. The set continues to run.
Any 142V (4 lines) lost to the panel or a loss of any 
return line from the panel will cause the error line to go 
high.

The drivers Q401~Q412 ground the LED blocks, 
(12 Total). If a block is not lighting after 6~8 seconds the 
error line will go high. 116V will be present on top and 
bottom pins of P204 and P205 (D245 cathode), you can 
ground the top case of the driver to the defective block 
to turn it on. If the block turns on, the panel is not the 
problem.

Note: If a particular block is exhibiting a dimmer level that the 
other or the overall brightness seems dim, be sure to first check 
the customer’s Menu setting for Backlights. Raise the percentage 
and see if the overall brightness returns to normal. If not, 
1st: Check the P-DIM level, it should rise with the percentage 
shown on screen. 100%, 3.3V. Follow the P-DIM signal all the way 
to each Inverter. 
2nd: Turn off the set and unplug the connector to the Inverters 
coming from the Main board. If the brightness returns to normal, 
the Main board is defective.

SMPS TEST 1: To Force Power Supply On.
Disconnect P8000 on Main board.
(A) Jump pins 9, 10, 11 or 12 (3.5V) to pin 1. (Test Voltage Outputs 
12V, 24V to Main and 24V to both Inverters). Remove AC power. 
Leave the jumper in place.
SMPS TEST 2: (B) Jump pins 9, 10, 11 or 12 (3.5V) to pin 18 (INV-
ON). Apply AC power, the Backlights should turn on.
Note; If Inverter Main or Secondary is loading down 24V, each 
Inverter can be run separately: 
Remove AC and Disconnect P204. When AC is reapplied, the 
Backlight LEDs on the Right (Back View) should turn on.
Remove AC and Disconnect P205 and reinstall P204. When AC is 
reapplied, the Backlight LEDs on the Left (Back View) should turn on.

Note: If a particular area is exhibiting a dimmer backlight level than other areas or 
the overall brightness seems dim, be sure to first check the customer’s Menu 
setting for Backlights. Raise the percentage and see if the overall brightness returns 
to normal. If not, 
1st: Check the P-DIM level, it should rise with the percentage shown on screen. 
100%, 3.3V. Follow the P-DIM signal all the way to the Inverter. 
2nd: Turn off Local Dimming in the Customers Menu or unplug P832. 
If the brightness returns to normal, examine the signals required for Local Dimming. 
(SIN, V-SYNC and SCLK). Suspect the Main Board.
SMPS TEST 1: Force Power Supply On.
Disconnect P502 on Main board.
(A) Jump pins 9, 10, 11 or 12 (3.5V) to pin 1. 
Test Voltage Outputs 12V, 24V to Main and 
63V to the LED Backlights. Remove AC power. 
Leave the jumper in place.
No Backlights. 63V to Backlights reads 56V.
(Leave Jumper in place for next test).
SMPS TEST 2: Force the Backlights On.
(B) Jump pins 9, 10, 11 or 12 (3.5V) to pin 18 
(DRV-ON). Apply AC power, the Backlights 
should turn on. Note, the LED B+ will now be 
65V.
Note; If there is a problem with a load from the 
panel backlights, you can remove AC and 
Disconnect P202 or P203. When AC is 
reapplied, the Backlight LEDs should turn on 
for about 4 seconds and then shut off.
Error line goes high.
