Question about Dell 2300MP Multimedia Projector
When I display a dark image, dust specks show up as dim white blobs in the picture. When I set the zoom and focus to their extremes, the dust particles come into sharp focus. All I need to do is remove the cover to clean off what I suspect is a dusty mirror inside the projector. I've tried to take off the cover, but it doesn't move easily even with all the screws seemingly holding it on removed. I don't want to break the cover, so I need step-by-step instructions on how to get the cover off safely, assuming doing that will expose the dirty mirror and/or lenses. I'd also like to know what the best way is to clean the mirror. My can of compressed air warns users to "NEVER" spray it on a camera mirror, but that it's OK for use on camera lenses. I've searched, but the Internet yeilds no results for service manuals for the Dell 2300MP.
Clean the mirror with a large, soft artist's brush. You can clean the lenses with any camera lens cleaning stuff as long as you don't use any paper products. Paper towels, napkins & tissues of all kinds will scratch the coatings. I use long cotton swabs. You will also find a small, dark grid like piece aimed directly at the mirror. It is like a tiny picture tube. Carefully clean the dirt film off this. Many digital cameras also fail when things get filmed up over the years.
When cleaning ANY type of lenses or mirrors, in or on anything, always use only cotton or silk to wipe them. Anything else will cause damage.

There are four very small phillips screws on the bottom of the projector... remove those.
There is one very small phillips screw on the right hand side of the unit if you are looking at the projector from the front.... remove that.
Now flip the unit so it is right side up and remove the top piece of plastic (The bottom doesn't come off at all. BE CAREFUL, THERE IS A RIBBON ATTACHED TO THE TOP PIECE SO LEAN IT AGAINST SOMETHING.
Now grab a vacuum and your air compressor (or can of duster) and go to town. There will be huge plumes of dust come from under the lamp so keep your vacuum close.
Next take the lamp out and clean off the glass lens (there is probably some dust on it)
Put it all back together and it should work like a charm
