I have a Mitsubishi WS-65313 wide screen HDTV. It is about 3 years old and I am experiencing a problem, that I believe is burn in. I watch alot of shows in 4.3 format, therefore, there are FILLER black areas on the left and right side of the screen. I just noticed about a month ago, while playing my xbox 360, that when the screen is displaying white or bright colors on the screen, the center part of the screen is slightly darker than the two edges (the brighter edges are the EXACT size of the filler area when watching TV in 4.3 mode!)
