Hi,

I turned my TV on this morning (after it working fine last night) and instead of a picture there are vertical rainbow lines on the whole screen but I can hear the sound fine.

Can anyone help?

Hi. Replace the lower Y driver PCB's and buffer board as well as the YSUS board. When you get the price of spares for a BIY job you may also consider the land fill option wher all plasmasmade by LG belong.

The screen on my TV lights up but there is no video signal. I have replaced all boards and still no video. I put the screen in a LGA TV and I have the same problem. I have audio but no screen video. Now I am at a loss. Is it possible that there is a defective screen?? Thsnks Ragan
