Remove lamp cover and lamp before starting disassembly. Pull the connector out and take out the 2 screws that are circled, then pull the lamp out.
Take the 4 screws out of the bottom of the projector and pry the front cover off by using a flat blade that will fit into the vent slots on the front and undo the three clasps that I have circled (I used a thin screwdriver, but ended up breaking the clasp on the far right- as you can see). A small flashlight will help you find exactly where the clasps are.
Remove the screws from the back panel of the projector as indicated from the red circles. There are also 3 more clasps that will need to be undone. You can see me pretending to pry on one as I try to hold the camera steady enough to take the picture. The second picture shows the exact location of the clasps and the 2 wires (yellow boxes) that needs to be disconnected. *Note the projector is flipped in the second picture*
Remove the top cover of the projector. Remove the 2 screws numbered 1 & 2 in the following picture. CAREFULLY
slide the metal plate up and out toward the front of the projector, making sure not to let it contact the color wheel while you are removing it. Remove screw #3 and just push the small circuit board out of the way to continue working- no need to disconnect the wiring. Undo screws 4, 5 and 6 (next picture) and slowly remove the cover from the lens assembly area. Ignore the fact that my lens assembly has been completely removed from the projector in the second picture. That is part of the overkill in my disassembly when I was trying to find the mirror. *This is a good time to clean the lens with compressed air if you are having dust blob problems*
The screws marked #1 & 1b in the next picture hold the color wheel in place. I would suggest getting a helper to hold the color wheel assembly out of the way after you remove these screws. Don't touch the wheel itself, just handle it by the cable or metal area. Remove screw #2 carefully as well. It holds the metal bracket in place that keeps the mirror seated. There is a second screw holding the bracket in place that will be revealed when the color wheel is out of the way. Unscrew that, remove the bracket (carefully) and there is your nemesis.
I used tweezers and Krazy Glue to fix the mirror (working fine now for over 2 months). In my case, only one side of one of the mirrors had come loose, so I just had to adjust it with the tweezers and apply a little glue to the outside edge to correct the problem. After you fix it, just reverse the steps and hopefully you will have a clear image again! I would suggest testing it before putting all the housing back together in case there is a problem (The lamp cover needs to be on for the PJ to work, though). The clasps are not easy to undo, and I had to go back in a second time to make an adjustment, which was a pain because I had everything completely back together.
YAY, all fixed!
Keep in mind, I went by memory on the details of the disassembly, so if I left out a screw to remove here or there I'm sorry, but it will be pretty obvious when you get there. The main thing is getting past the fear of opening your PJ, knowing where the mirror is and how to get to it, which I hope this tutorial helps you do.
