Hi, I have a 64 in Pioneer Elite 710 HD, and I noticed something a few weeks ago that I've never seen before. When watching "Tears from the Sun", during a scene where the screen was "very" dark/black, on the left edge of the screen there appeared to be some kind of discoloration that was slightly brighter than the black background. This "discoloration" (for lack of a better word) ran from the upper left corner to the bottom left corner, or from top to bottom. Well I had never seen it before and thought maybe it was the disc, so I subsequently forgot about it until the other night when I was watching another DVD and I saw the same thing, in the same place on the TV. I was wondering if you had any suggestions as to what is causing this? There appears to be nothing wrong unless the screen is totally black, then it becomes very apparent.
