Question about LG 50PX4DR 50 in. Plasma TV
LG Plasma 50PC3D turns on, clicks and then turns off. There is no sound, no picture.
The power supply is going in to protect mode. Most often this is a power supply failure, or a failure on one of the circuit boards that is causing the power supply to go in to protect.
If the power supply fault is not too complicated an experienced tech may be able to service it without changing the compete circuit board.
The tech will service this by substituting boards to determine where the failure is occuring. Then he will change the board to fix the fault.
