I have 2 NP-200 projectors installed in a school which show white dots on a black background and black dots on a white background. This is caused by the DMD chip losing pixels. Only solution is to replace the chip, I'm researching now if that i an economical solution.

White dots all of screen


sound like you have a bad dlp chip. this happens to a lot of samsung dlp tvs. some of the mirrors are stuck. they can appear as black dots or white dots and it usually gets worse over time.

I have white dots appearing on my samsung dlp.


If the white spots are appearing in different spots or "Moving" it is the DMD board beginning to fail. Samsung DLPs seem to have a lot of DMD board failures. I would expect it to completely fail in the next couple months.

If there are only a couple small white spots that never go away it could be a mirror that is seized on the chip, but it's far more likely that the DMD board is going bad.

White dots all over screen


this seems to be an issue either with your DMD board or with your Digital Video board... turn on the tv and go to the menu if the white dots appear on the menu the issue is with your DMD board but if they don't show on the menu, the issue would most probbaly be with your Digital Video board
