When you start seeing white spots, there is a chance that the DMD board(the one in charge of the pixelation) is the one defective. But it could also be the Video Board, a way to know which board it is, is the next way, go to your TV menu and if the dots still show up on the menu, it's the DMD board but if they don't show on the menu, it's the Video board. www.discount-merchant.com?Click=48427 The boards are not that expensive, they're running around $180dlls

Good day, Our samsung DLP set has recently started shutting down the picture as we watch a movie. The picture disappears, and a white patch of horizonal lines appear, which covers about 1/4 of the screen area. The sound continues for the movie, even though the picture is gone. We have times when the picure goes completely black, and the sound goes too. It can be corrected by turning off the set and waiting a while and again turning on the set. In advance thanks for your help. Don Back

there are spots on the tV that are tiny white dots. It appears that some of the tiny bulbs have burned out and I wondered if it can be fixed. There are about 5 or six scattered across the screen.
