Optoma HD26 DLP Projector Repair Noisy and Shuts Down

I picked up this Optoma HD26 from a guy who had bought a new lamp for it but the new lamp didn't work. He decided that was his excuse to get a new projector so I bought this off him for $50 plus shipping.

Upon receipt, I first tried it and the color wheel was making an awful noise. Not a grinding but a weird squealing/chirping noise. This is common when it can't regulate it's speed for one reason or another.

In this case, the problem was due to heat. The foam under the color wheel has become loose and curled upwards. This caused it to be cut into the color wheel and the index mark came off as well. Once the index mark fell off, the color wheel position sensor was no longer doing anything.
No new lamp would have solved this.

In the past I have used Marks-a-lot markers to replace missing index marks or stickers from other color wheels that no longer work. I happened to have another projector in the scrap pile that had some un-used high temp black tape. I cut of a tiny bit and fit it to the wheel as you will see.

I don't know what kind of tape it is though. I would love to know. If you happen to know adhesives or tapes, and have an idea on where I can source this sort of thing, please let me know.

Everything I have learned about repairing projectors has come from trial and error as well as reading the service manuals. I also learn a lot from other hobbyists out there who take a stab at repairing these. Hopefully someone has some insight on the tape. It seems trivial but it might save others some hassle.

I still ended up ordering a new color wheel. This one had been over-spun so many times, I think it's noisy, or at least noisier than it should be. Plus it was only $30 shipped from California.

Let me know if you are interested in seeing another color wheel replacement for this HD26.

I did put a new lamp in. That made a lot of difference in the image. The old lamp had 3700+ hours in. That is worth replacing.

Lastly, if you are in the market for a 3D compatible 1080 projector, let me know.
This one is for sale. The new color wheel will be installed this upcoming week. I'm asking $250 plus shipping. No remote unfortunately. They are going for $300 plus shipping on flea-bay. If you want one, give a shout.

Thanks for watching!
