My wife is a teacher and her NEC NP200 projector works fine for about 8 - 10 mins then all the colors begin changing on the screen. The colors change very rapidly kinda like a disco ball. I would like to fix it myself. What could be the problem? Also, any disassembly assitance would be great.

You tried three notebooks, but did they have the same video adapters? Try a notebook with a different video adapter. i would say your video adapter isn't good enough to put out a dual display. you might need to get a laptop with a better video card
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.
I have several white dots all over the screen. They're more that pops up as I watch it and the dots never goes away. Does anybody know what I need to do to fix this problem? Thanks..
I have about 10 of these in the school I work in, most of them have gone mental flickering, my solutions has been to open the covers remove the bulb and carefully using a compressor blow all the dust out..This has worked and cured them in about 6 out of 8 cases
Phone NEC and get them to swap it over if it is under warranty. They are very good like that and you will have a replacement next day via TNT. Take out the bulb and keep hold of all the cables and remote as they will send you the projector only. Put the faulty one in the box and send it back. TNT will collect it and it is part of the returns policy. No cost involved.
I'm a techie with a school district and have the same problem. My suspicion is it's a lamp issue, though the teacher using it says there was no low hours warning. Unfortunately I don't have a spare to try out so if anyone can state categorically that it IS the bulb then I will purchase one.
