Infocus 3916 Projector goes in and out of focus. It is a little less than 2 years old. Any suggestions for a solution?


Many of these projectors have a manual focus, and an auto focus. Make sure the auto focus is turned off in the menu options.
Then make sure the manual focus is not moving on it's own from vibration of the cooling fan. You can check this by manually focusing the projector, then taking a marker and marking a line on the focus wheels. If the projector goes out of focus, check the line you made and see if it has moved, if so. Your projector is going out of focus from vibration of the cooling fan, or the surrounding environment.
If your projector is mounted to the ceiling you can add a couple of rubber washers between the projector and the mounting bracket to cut down on vibration.
If your projector is sitting on a desk / table / ground, you can use foam padding to keep it from vibrating.

another solutions would be to temporarily tape the adjusting knobs while the projector is in use.
If your projector has a protective cap that is put on the lens when not in use, this will also push the lens out of focus, and will need to be re-adjusted each use.

You need a replacement color wheel (that is the name of the broken plastic disc, likely glass). I have been unable to source one. Recommend you buy a used projector with a bad lamp, usually less than $100 on eBay and just put your good lamp into it. Keep your old one for parts.
