The problem started out with 1 thin vertical red line that showed up one day on the screen whenever the tv was on. I trouble shot the satallite (dish network) and it wasn't associated with that. It got progressively worse with a second line, then a 3rd green line; and now there are several multicolored thin, vertical lines on the screen constantly. Turning the tv off for a while lessons the intensity of the colors, and unplugging it completely for hours does not make a difference. Can anything be done to fix this?
