Bought a brand new Toshiba 27" non-flat TV yesterday. For the first hours, I didn't notice the darker top left corner because I was watching widescreen DVDs. Then I switched to cable and there it was! The top left corner has a slightly darkish tint to it. Nothing is obscured, and the tint only goes down about two inches. There are bookshelf speakers on either side, 14" away and a center channel on top. Moving the speakers around doesn't make a difference. At lunch I will try the TV in another room, but if this is something known and/or fixable I REALLY don't want to pack it up again and attempt to take it back to Best Buy by myself. Really strange coincidence, my 3 year old 19" Sony Trinitron monitor also has a darkish/bluish tint to the top left corner and a reddish tint to the top right corner, which started when I moved to my current residence two years ago. I just assumed it was getting old. Any info would be welcome!
