Projector, clean dust off of main board

This should probably only be done if your warranty is expired. Dissembling a Dell Projector will void any existing warranty.

Personally I had nothing to lose, the projector wouldn't work and Dell wouldn't help me so I had a $1500 pile of plastic with no good use.

If your projector is flickering, the picture is jumping up down left and right, then it shuts down and the lamp light comes on, it is not the lamp! Don't let anyone tell you otherwise! Well, at least try this first.  For some reason dust on the main board causes this, sounds ridiculous but it's true. I have a 3200MP < ADMIN NOTE:   Broken link has been removed from this post by Dell>
 and just did this two hours ago and the projector is as good as new. 

 

For a 3200MP projector =

* Take the projector to a work room. This will get messy
* 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 projector if you are looking at the projector from the front. Remove it
* Now flip the projector so it is right side up
* Remove the top piece of plastic. The bottom does not come off. Be careful. There is a ribbon attached to the top, so lean it against something while disassembled
* Use compressed air can and blow the dust out of the unit
* Take the lamp out and clean the glass lens
* Reassemble the projector
