White dots on screen

I believe it is the digital projection chip that is beginning to fail. Causing white and black spots to appear. To repair this may cost more than a new tv. If you want to attempt it yourself check out the above link. Hope this helps

I have nec np200 and there's a lot of dots appeared on the screen. what seems to be a problem


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 dot for DLP Projector TV is not because of the light buy. It is caused by aging DLP chip ( DMD Chip.) Your TV DLP Part should be the following image:

Three small white dots have appeared on the screen. What does it mean, is the lamp going bad?


White dots are caused by the DLP chip failing.This part must be replaced to get rid of the white dots. Samsung is covering the cost to repair this problem on several models. Ypu can call 1-800-samsung to find if your unit is covered.

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.

I have white dots on the screen of my hsl4266wx/xaa?


If these dots are only seen when the picture is on I would look for the Optical Block to be causing it. Are the dots in the same place each time you turn it on?
