Question about LG 42PJ350 42 in. TV
The TV model is LG 42PX4RV-MC. The problem has started like this:
The TV was powered on, working good about 1 hour. Then, suddenly, I heard a loud noise seamed like some “glasses breaking/exploding”. After this noise, the TV image has disappeared. Only the TV’s sound is working. I don’t have any TV’s electric scheme or block diagram. I opened the back cover panel and noticed that the fuses, from both boards, that have flat cable connection to the picture screen, were burned.
Only the power board is with its fuse ok.
Now I’m asking if the problem becomes from the Plasma Picture’s “SCREEN” or it could be any other problem, like an “over voltage”, from the power board, that could damage the other circuit board and their fuses?
Thanks in advance,
The problem with this set, is defective YSUS board, to avoid future same problem, you must change the following boards: YSUS, ZSUS & Control.
