I could really use a service manual, schematic, or fix. For this TC-L32C12 it is dead. no sign of life. It has 3.3 volt on power button, it has 5.2 volts on standby power supply voltage. No other voltages. checked all fuses. I have checked all caps for ESR. I have looked resoldered any joints that look bad. None of the boards read for a direct short. I have checked transistors, diodes resistors and everything looks good, sight, sound, and smell. I am t at a loss. I need help! There is no sound of a relay click or oscillating.
