Maybe the problem is inside the TV? Not much help, is it?

Well, that's about the best I can do with the information you gave. If you had spent a few minutes with a camera, then attached a picture, I could give a more definitive answer.

This problem is due to either the logic control card, the X buffers, or the plasma panel itself. If the pattern is in a repeating pattern it's most likely the logic control card. If there is no pattern it's the buffers or the panel. Since the buffers are usually bonded to the conductive tape, either of the last two causes is unrepairable.

Pictures help us help you.

Thanks for the reply

Apologies but I only have a very basic knowledge of these things if its not a simple part replacement I was hoping to get a replacement board or if I can narrow it down have it looked at by a friend who is much better at this stuff

The pattern on the screen is constant in all inputs although it has flickering pixels within the lines on the screen

Can you tell me what connections go in / out too the logic control card to help me identify it and I will strip the card out and photograph it back and font properly and post them

The logic control board is behind the main board. The main board is the board with the input connectors.
