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

After turning on the projector, press "+" and "-" buttons on the control panel
simultaneously for 3 seconds and release the buttons when screen goes blank.
2 Press "+" and "-" buttons again to exit the diagnostic mode.
3While in Self-diagnostic mode, the screen will run a seven-color-cycle test as
Red--> Green--> Blue--> White--> Watchet Blue--> Dark Green--> Yellow.
Ensure that the colors of the test pattern are correct. Contact Dell if the colors are
not displayed correctly.
