Question about InFocus IN83 Projector
I had the same problem so removed the bulb which is very easy, only 3 screws, found the wire mesh inside was covered in dust so vacuumed using a brush head attachment, removed all the dust & did the same to all the external vents too. The projector now runs smoother, quieter & does not over heat after hours of continual play. Hope this helps, Chris

Most likely, if it is a thermal problem, your main cooling fan has quit or is stopping after a short period. The problem is, I've seen several of these do this, and in every case, it is not the fan that has failed, but the Controller Board. And that is a very expensive part.

Yeah, strange enough the lamp timer was already reset. I think whomever had this projector before me had tested it before selling it. Thanks for the response, though!

SOURCE: Bulb failures
I experienced the same thing, only to discover it was the ballast that powers the lamp. I believe INFOCUS repairs for $390.00 per the technician that I spoke with on the phone at INFOCUS.

The fan is probably on it's way out and cannot produce enough air flow to cool the lamp. Replace the fan with the same ratings as the original and it should work fine. The only other thing would be a problem with the power supply not supplying enough power to the fan, but, a bad fan is more likely.
