Not too sure how to explain this but here goes: While watching a film last weekend I noticed a very slight blue tint along the line where the picture hits the top black bar. This goes half way across the screen and only occurs on light images. If I stretch the image and remove the bars the picture is perfect. It occurs on whatever source i'm using. Not sure if its relevant but also bought a REL same day and originally placed it next to the TV but can't be sure if that caused the problem as it isn't immediately obvious and reading all your advice it does not sound like a magnet problem. It's a very trivial problem but now i've noticed it, its really annoying me !!! Any help would be greatly appreciated.
