Own a Samsung DLP TV 42 inch and white dots have

The random whit dots you are seeing is more than not the DMD or million little mirrors board. The white spots represent some of the mirrors that are sticking in the on position. In that case they are always reflecting white light from the lamp. I don't concider the DMD board a do it yourself repair since on the older DLP set it requires mechanical alignment as well. The best thing to do is contact a techincian and see what they might charge to repair the TV for you. Please take a few moments to rate my answer...Thanks..

The cheapest solution is to replace the DMD Chip since this is the cause of the white dots on the screen. Unless your very technical, get your service repair person to do this.
