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 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

Dusting is not going to help. I could be the lamp if it happens with no input hooked up.

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..

sounds like an electronic problem rather than an optical fix.
Has she changed the setup of the unit recently

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.

hi, it depends how you connect the DVD to the projector. the projector itself has only one speaker (mono) - not so good for movies. the "audio in" is a mini stereo plug (same as headphones). you will need a RCA to mini stereo convertor - red/white (or red/black) RCA to mini stereo plug.
or you can connect a RCA to RCA (red/white to red/white) cable to an amplifier which is connected to speakers.
or just plain speakers, but you'll probably need a convertor cable from RCA (red/white) to a female mini stereo plug).
these cables are pretty cheap and can be bought in any Radio-shack.
hope it helps....

What input are you using and what is your input source?

Based on the information provided, it is possible that there may be an issue with the projector's power button or internal components. It is recommended to try the following troubleshooting steps: 1. Check the power source: Ensure that the projector is properly plugged into a working power outlet and that the outlet itself is functioning correctly. 2. Reset the projector: Some projectors have a reset button or option in the settings menu. Try resetting the projector to see if this resolves the issue. 3. Check for internal issues: If the above steps do not work, there may be an issue with the projector's internal components. It is recommended to contact a professional technician or the manufacturer for further assistance. In summary, if a NEC projector indicates light when plugged into a power source but does not turn on when the power button is pressed, it may be due to issues with the power source, internal components, or other factors. Troubleshooting steps such as checking the power source and resetting the projector may help resolve the issue, but professional assistance may be required if these steps do not work.
