I'm very sorry for any inconvenience this may have caused you. Unfortunately, this sounds like it may need servicing. Here's the thread where you can get details on setting that up: http://forums.cnet.com/7723-13973_102-542437/service-issues-click-here-for-help/
I have had the issue mentioned above for several months, 4 bands across the left 2/3 of the screen where the picture seems to cross over each band in various magnifications.
Does anyone know what causes this and if it can be repaired? The TV is less that 3 years old so it out of warranty but I really dont want to have to spend on a new one.
