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.

Black dots projected on my 3m scp716 projector


Actually, this is a known issue with this specific model as 3M has acknowledged. We bought 4 of these and 3 have had to be replaced in 3 years because of this exact issue. It requires the mainboard to be replaced and it is almost as expensive to do this as to buy a new unit. 3M has been know help to us on this even through we bought the entire setup (Projector, Arm, Smartboard) and spent over $15000.

I HAVE RED DOTS ALL OVER ANY BLACK COLOR OF THE PICTURE


Could be whats known as dead pixels, this is tested be showing up a black or white screen. Microsoft paint or word will do. If an area always has dots then dead pixel. However if it doesn't constantly remain a dot then, some-thing else. Dead pixels come about due to age.
A technician will be able to diagnose your problem by performing white screen test.

Smartboard will not work


If you tried 7 different laptops yeah, the problem could be with the smartboard. Try another one and see what happens.

Otherwise we'll just be guessing.

First, order by number. Some illustrations are general. Second, you may find a board rebuilder who will fix yours or exchange it.

I've done this and found that the correct product was sent and worked well.
