SimplifiedBACKLIGHTS Test
1. Activate Backlights – Disconnect Lead Cable from Main to Power Supply.
2. Measure BL Supply voltage at 1+ or at the supply diode cathode (stripe).
3. Remove Panel connector and measure again to compare.
4. If voltage is high and stays the same high reading a string of Panel LEDs are open. Replace the Panel.
If the voltage is low and remains low the SMPS is defective.

Damaged Panels
Panels do not crack on their own
41
LCD panels use a flexible polarizer on the outside edge of the panel. If the unit is hit by a object the flexible polarizer may not show damage but the inside LCD glass will break. Panels showing a center point and cracks radiating from that point is impact damage. Corner cracks are usually the result of rough handling. Panels do not crack on their own.

T-CON
Testing
Check 3 LED Indicators for operation (All On when OK)
Measure 12V T-Con Supply at both sides of Fuse ref to ground. (If it’s missing on both sides check LVDS/Main Board feed; If Missing just on one side, check fuse/T-Con Board) 
Check LVDS Connector 
Check Panel Connectors

3 LED Status Indicators
 3.3Vdc Reg. / 12Vdc Reg. / Panel DC/DC Drive 
All three LEDs must be lit in order for the T-CON to operate correctly. They monitor DC regulator supplies on the T-CON Board. If all three LEDs are out then the fuse is likely open or there is no 12V supply voltage coming from the LVDS Cable/Main Board. The left LED is the 12V Supply Regulator and if its out no Video condition, the Middle is the 3.1V Regulator, if it’s out: Noisy Picture, the Right LED is the T-CON DC to DC Converter (approx 17 pending panel size) : If it’s out no Video.
