Optoma HD20 Projector Cleaning

I had someone drop off an Optoma HD20 DLP Projector. Their complaint was the colors would start to flash and the projector would shut down. Because of the symptoms, I suspected a dirty CW sensor. The insides turned out to be pretty dirty, but a good cleaning did it right. I also repaired the cracked screw socket that holds the top on. This just shows how you need to clean your projectors. I recommend seasonally. Thanks for watching!
