Dell 1100MP Projector, unit stopped working, I assumed it needed a new bulb months ago. I got one today and it appears it is a fan issue. Lamp/Heat lights orange on start but picture fine, auto shuts off in 2 minutes or less with Temp light flashing orange. Seems I need fan, but I can't seem to get the case off.

This is a very common problem with these projectors. The fans lock up and the units are out of warrenty. The fan you replace it with must be the exact same as the old one, even though it is the same as a 5$ computer fan. The processor will detect the non-dell fan and shutdown in the same way.I Havent been able to find any replacement fans that will work. I may be interested in buying your broken projector from you if you give up.

Email me at: nalexandrov251[A-T]gmail.com and we might be abe to work something out.

There is one last screw that you may not notice next to the lens. You have to take a knife and pop a cap off to get to it
