LG Plasma, no picture, black screen, but have sound. I can change the channel and hear sound, but there is no picture.
Most a likely a problem with your Y-Sustain board which will then not drive the screen giving a black picture. The fuse on the board may be open circuit & need replaced but most likely you will need to have the sustain board replaced.
I had exactly the same problem it was a fuse on the y sustain board.
i solder a little wire fron point a to point b you will need a voltemeter to find out wich is the bad fuse their is about 7 fuses on the board
I will join a class action.
I have the same problem, black no picture or sound, it looks like LG plasma TV has this inherent problem of Y nd Z SUS board going bad aftr 2-3 yrs, I called the excutive office-877-543-8325, they did not help me at all, I explained to them that it is inherent problem, and they should at least mail me these board, they did not show any co-operation. I will never buy LG, and am soembody should take legal action agianst LG
