Please - Need help on this issue. My dad's Sony 50 inch LCD HDTV appears to need degaussing, although I know that LCD doesn't ever need it! On the right hand side of the screen there is a distinct yellow/green hue to the image - top to bottom - about maybe 6-8 inches on that side. On the top of the screen there is a magenta hue horizontal across the TV - about 4 inches wide. What could be causing this issue? The TV is only 2 years old. I've already contacted the service department where he purchased the TV and they will be having a tech come up possibly by next week (although I'll have to pay for it). Does anyone have any clue what could be causing this issue?? I scoured the entire internet and cannot find anyone with the same issue - at least in the same manner I'm describing it. Any ideas??
