    Most Dlp/dmd chips have a 3 year warranty. They cost between 200 and 500

You have a bad DLP/DMD chip. They are fixed under warranty. Or you can buy them.

I would have it serviced under warranty from Dell as it could be the mirror array going faulty and that is expensive!.

the light filter on the blue lcd panel is fried due to excessive dust and heat. clean out the projector with canned air. unfortunately, you cannot buy individual parts of the optical engine- you'll have to replace the whole thing. or live with it.

SOURCE: Help! Our Optoma DLP

There is a lense behind the main focus lense that's causing this. Flakes of the colored tint are coming off causing white light to shine through. If you look at your projection, you can see black spots as well, these being the flakes that have re-located themselves. I dug into mine deep enough to diagnose this, to actually replace the little lense would be a little tricky. The unit has to be mostly disassembled. Also I haven't been able to locate a vendor who sells the part. Optoma wants you to send it in so they can do the repair, and won't part w/ these component level parts.

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.
