Was repaired once before under warranty for this exact problem. In that case, the PC board was replaced.

That is what is called BURN IN or as the manufactures call it "IMAGE RETENTION". Basicly what this means it that you have been putting more hours on the part that is darker the smaller part, or the 4x3 picture or the square part. And, basicly the part that appears to be lighter is "LESS" worn out than the other part of the plasma tv. There is no fix for the problem, But if you go into the menu and select "BURN-IN" OR "Pattern sweep" or WHITE Screen than you will see exactly what i mean. Now, you can keep it on this pattern overnight if you would like, but i suspect it will not cure the problem, but lessen the effects of it. But keep in mind, you are reducing the life of the complete panel when you do this. Not that it is bad to do this. If you have anymore questions don't hesitate to ask anymore questions. The better fix is to Switch over to the "Dish Network and than you can format the screen on any channel in any mode. Superior product to cable. Have a great day. And watch out for the snow storm coming. GURU JAY

Hello, I have a question which video inputs are you using for your DVD and Wii connections? The reason I ask is because this sounds like video distortion cuased by noise. If possible can you send a picture of the screen when it has this problem and send which video ports are being used? If it is noise in the video you may have a saw filter problem, or a decoupling issue. In any event I'll know more once you send those pictures and which inputs you are using for your DVD and Wii.

If you can open your LCD and clean all connector given and refit properly.don't use force to remove connector just try to softly remove.

You are having another problem with the power board...there are some capacitors which are easily replaced to cave you the cost of the board. If you are technical,I can guide you further,other wise a reputable shop can fix this very reasonably

Update: LCD Panel is bad. After being off for a good while. The TV functions momentarily after power up, but once the panel heats up, it starts pulling voltage from the main board. Not worth repairing.
