Question about InFocus ScreenPlay 4805 Multimedia Projector
What I have just finished doing with my x2, because it was the controller board not giving enough voltage to the fan. I used my kiwi initiative and hard wired an old nokia cellphone charger transformer inside the projector and connected to the 240V inlet from the underside of the power supply board, this worked brilliantly and supplies the fan with the power, the only dis advantage is that the fan will keep spinning as long as the projector is plugged in (could be easily fixed with a switch), but the way I see it it's better for me because it cools the bulb down a lot longer. Saved me from buying a new projector Lol, if you would like I can send a pic of what I have done?

Most likely it's overheating. And the most common cause of overheating is the fan. I would suggest you open the case and find the fan, and clean it out - most likely it will just require giving it a good shot of canned air (which you can buy at any electronics or hardware store). With luck, it may just be jamming on or be impeded by a buildup of dust.
If that doesn't help the problem, and you find the fan doesn't seem to be turning, let me know and I'll try to find information on ordering a replacement.

I have the same problem. I've verified that both fans are turning, but it seems it's not enough to cool the projector, which shuts off (thermal switch next to the lamp housing cuts off) after only a few minutes. I'm working on a fix to mount an additional external fan that can "****" air out of the front grill.
