SOURCE: Vertical black lines. But they are not solid. lg plasma 42pc3dv

This could be a poor connection with the LVDS cable which runs from the main video processing board to the screen, or a fault within the video processor on the main board. Worst case scenario is it could be a fault with the screen itself.

SOURCE: LG tv starts up with a grey screen with colored

Grey screen means the T-CON board is not getting the 12vdc feeding it, same for sound. So check to see if you do have 12vdc from the power supply first.

Black Vertical Lines in screen


All I can tell you is that you maybe have left your T.V. on a channel that didn't move for so long, or maybe someone else did and it burnt the screen. Plasma's run off of plasma gas to create the great picture and they collect on the screen and stick. What you need to do is go to your menu and look for "screen burn protection" and put it on white and let it sit for 20 minutes. All of one color such as white doesn't harm your T.V. The only way anything burns is like a bright white line in front of a black background.

Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.
