Very noisy projector, I can see that the noise comes from a broken color wheel. How to pray open my Infocus LP130 to reach to the color wheel an maybe fix it or replace it.

It's been awhile since I worked on one of these, but I believe there are 2 screws on the rear and 2 screws on the bottom that have to be removed. Then there is a slot on the front bezel which if I remember correctly is on the side of the front bezel furthest away from the lens. Stick a small flathead in the slot and slide the release in the slot down. You should see that end release and then pull the front off. Pull the rear off by popping it loose with the flathead. There is no slot for the rear. It just sort of snaps in there between the top and bottom covers. Then unplug the ribbon cable from the board under the top cover and remove the top. Have fun and good luck on the colorwheel. The segments precise and I don't recommend gluing them back in especially if you aren't sure of the sequence. Lastly, it could be hard to find one for this model because the service life for this model ended around 4 or 5 years ago and may no longer be supported. Google Infocus and go to the website and see if you can get one.
