I have an LP600, and the internal mirror is broken. It is a small 4-sided box that is made of mirrors, behind the color wheel. It was cutting off half of the image on the screen, so I took it apart and found that this little rectangular box had one side out of whack. Upon looking at it further, I found that the glue had just broken and not the mirror itself. Is there a way to fix this, or does someone know where I can get just this part? I didn't pay for the projector, it was free from my work, and I can have it. I just want to get the part or a way to fix it so that I don't have to pay an arm and leg for the repair. I don't have any images to show....

Power locks/windows/and mirrors, all have wiring connections within the door panels. Connections may be broken/unplugged. Check and spray electrical cleaner on the plugs internal parts. Also, main switch panels may be broken individually, but not likeley. Check all fuses that power these items.
Steering wheel noisy while turning may be worn steering bearing on shaft. Check and replace as needed.
I believe you can't get the internal parts of the mirror head. you can only buy a new mirror (just the glass) or an entire mirror head assembly.

It's the light tunnel. The tunnel is a square tube made up of 4 mirrors glued together.
It looks like this from the side: |_| (with a piece on top too.) When the glue breaks down, it shifts inside the little mirror holder. The shifted mirrors looks like this /_/ what you are seeing is the shadow of the tilted mirror tunnel. ON the RCA's there's not a good fix.
RCA's response: "Ok, well sadly they do not offer the light tunnel anymore, which is what you need. Sadly you would be rendered to get a whole new light engine assembly. That would be the D.N.D module, light tunnel,color wheel,optic spanner, and oci. mirror. Your best bet would be to search ebay for a broken engine and replace it that ways."
That is the ONLY response I got from them.
I took the set apart and found the 4 tiny mirrors. I will be attempting to epoxy them together. (The set is dead anyway, why not try?)
Well without seeing the damage I would have thought Superglue would be your answer and just re afix the mirror if it is indeed undamaged .
Otherwise as it has a working bulb ( usually worth more than the actual machine? ) Maybe a replacement unit off ebay can be obtained you would also have a spare for any other repairs . .... Regards Vortash
Single chip DLP projectors use a spinning color wheel between the lamp and the DMD (mirror chip) to produce colors. If the wheel rotation/synchronization is disturbed, colors will not be displayed correctly. In my case it looks like the wheel became un-synchronized, probably because the projector was dusty/dirty inside (a light senor is used to detect the wheel position), resulting in a grainy, slightly flickering image. I simply blew out the components with a can of 'Dust-off' and, using a small tool, rotated the color wheel by hand to make sue it wasn't rubbing or jammed. I reassembled & started the projector and the image was back to normal.
This is the same problem as other posts have mentioned about the right side of the screen having a bluish-balck stripe down the side of the screen. Here's what's happening. There's a small light tunnel which has 4 very small mirrors located just behind the color wheel. The lamp shines light through the color wheel as it turns and the light goes through this small tunnel and is then relected off several mirrors before it is projected through the lens and onto the screen. Optoma apparently did not use a very good heat resistant expoxy glue when they assembled these mirrors and over time the mirrors drop down causing a shadow effect on the screen. It can be repaired without paying some repair shop a small fortune. Previous posts have a solution from another contributer whihc includes photos. I had to repair mine and it's worked fine since I used a decent expoxy to hold the mirrors.
