I have a u260W and now it shows white spots all over. what could be wrong and what could be done

DMD or DLP chip has died. Can be replaced by user if you have electronics experience equivalent to building or servicing desktop computers. Just replaced mine this week, actually. Good as new now. The part or chip number is on the chip itself. Once you have that number, you can usually find replacements on eBay for roughly $200. Kinda pricey, but way less than a new unit. I looked at some forums but found no listed DMD chip numbers for your projector:(. 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.

NEC LT260 has White specs on Screen

I had the same problem. It is specks of dust on the DMD chip that the lens focuses on.

If you take it apart you can see a long telescopic lens that points at a small chip. This chip contains all the micro mirrors that produce the image.

Fortunately this sensitive item has a glass cover. Unfortunately it can be contaminated with dust. I just squirted a jet of air from a camera lens blower brush to remove the specks of dust. Problem solved.

Here is a link to a dismantling guide: http://www.flickr.com/photos/todbot/81868083/in/set-1749030/


(If you get any dark shadows at the edge of the screen then the light tunnel between bulb and colour wheel has partially collapsed.)
