Hi, I'm very new at this TV stuff so please forgive my lack of knowledge. I have a Toshiba 42WT29B for just over a year now and I reduced the contrast etc as suggested, but just recently I've noticed what looks like a very faint 3" brown stripe running across the bottom of the screen. And now all I look at is the bottom 3" and not the rest of the screen. Also in the last day or two the TV picture has been going off and not going to the blue screen, the only picture I can get is if I change it to the digital TV bit and that is waving like crazy. I have to swicth the TV off and back on, then the picture is back. Any ideas what this could be? Thanks for any replies.
