We have an NEC NP115. It started doing the dead pixel thing about 2 months ago (the projector is about 2.5 yrs old). It started off with a single dot, and not has hundreds. There are both white ones and black ones, and now there are so many it is nearly impossible to watch. I'll be checking now to see if anything might be covered.

Yes you can get it with DLP but on LCD it is a mystery?

Just to say we've got 2 NEC NP215s now spraying white paint...well that's what it looks like...they are DLP.
None of our LCDs ahd this problem...our older LCDs started to go with a yellow haze.

Resurrecting an old thread, but this has recently happened to one of our Toshibas. The general consensus is that you need to replace the DMD chip: DMD Chip

Considering the cost is a third that of a new projector, I don't think we'll bother taking the chance.

We've gone with Epson EB-X11...bit of research shows Epson are rated the best for projectors...but I guess some of you knew that already.

[Marc-Engineer]

Yep we did, great value more cost effective than any LED projector make sure you get the 5 year education warrenty.
But what ever you do DONT BUY DLP for schools.

I've had an Epson do this... and an NEC - both LCD, turned out to be a driver chip breaking down (supplied by NEC) was more expensive to have repaired than to get a new projector.
