If no flim is presented thers white light and if the film is scracth you see it on the screen. If you don't see this problem other than watching a TV then it's your tunner. If you see this problem even playing other video signals, then it's the image processing. You need to take the TV to a shop if you really love your projection unit. Cost of replacing that parts could be anywhere between $200 - $500 depending on the component. New 42" LCD is around $1000. Can't find your answer ? Ask !
