Hi , i have a problem with a plasma LG 42PX3RVA, the set turns green when you press the power button but no picture or sound , i measure the voltage on the boards and found thay it was correct acco


Bulb overheated and probably blew, they are made of mercury most times so don't touch them they should be in a housing, that could be it. If most times dust gets in there and the fan gets weighted down with dust if its up against the wall no air flow, so there ya go, try that. good luck

My lg 42px3rv had no picture but sound so i changed the Y sustain board and now has a fuzzy line going across the screen with sound i don't know what to do, how do i fix this please help me


If the ribbon connectors to the y-buffer board on the left hand side of your tv (if viewing from the back) are not seated correctly you will get lines across your screen.
Not the same model i know but please check this video as i think it will help. If not then you can comment on there page with your issue and they get back to you.
Hope this helps.

My plasma tv has just lost it's picture. I do have


There will be a fault in either the Y or Z sustain boards, these are responsible for driving the screen 9hence sound but no picture). The popping sound willhave either been a fuse blowing on the board or another possibility is one of the drive ICs on the buffer board has blown. If so it's best to replace the board.
