I also am having problems with my 27 inch Magnavox Tv. When it comes on, a white line appears 1/4 the way down the screen, then about two inches of the picture disappears from top of the screen and the white line remains where the actual picture begin, and the black 2 inch section and the white line ends.

Anyone who could tell me what the problem is would be highly appreciated. The television was hardly used. It use to be in my television room, and no one watched the television in that room. About 4 months it was moved to my bedroom. So it may be five years old, but it should be as brandnew with very little viewing.
