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 dots on the screen


Need more info. But initial suspicion is there is a problem with your projector.

Are they stationary and always in the same position? You may have bad pixels.

Are the dots there with no signal going to the projector?

What is connected the the projector? Detail the video path - try all the sources. The dots still there and in the same position on all sources?

It is probably your projector.

If some of your sources are fine - the problem might be from a connected source.

Hope this helps.

Many white dots appears on the screen of my benq w600 projector


Jacob, what element on the mainboard is the source of these dots? I have the same problem - it is only one dot now, but I think there will be more with time.
Also, the second question is: how do I unscrew the mainboard from benq W600+? I remoced the metal cover, unplugged all the cables, but there's something still not letting the board go.

How do you clean the dust out of the projector, there are particles that look like small white stars on the black areas and black stars on the white areas. Is this dust?


If you focus the image on a screen up close to the projector and notice small rectangular black and white spots, then you have pixel failures.
