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.

Secure the lamp cover and the air filter cover of the
projector body if the projector does not power on. Ensure that the power
cable is firmly connected to the projector and an active power plug. If
the projector was turned off and then on quickly--let it sit for 90
seconds before trying to turn it on.
Replace the projection lamp if the projector will not power
on or if the lamp indicator is flashing. Turn off the projector and let
it sit for at least 30 minutes. Locate the lamp cover and remove or

projection lamp from the projector housing using the handle, if
Place the new projection lamp into the projector housing and
secure it to the projector. Replace the lamp cover and reset the lamp
timer. Power on the projector to ensure the new lamp is working
Remove the projector from the enclosed area to allow air
circulation if it constantly overheats. Place the projector into an open
area and make sure there is no blockage for the ventilation holes.
Unplug the projector for at least 45 minutes to allow it to soft reset.
Clean the air filter to allow the projector better air
circulation. Turn off the projector and unplug it from the outlet.
Remove the air filter cover and use a vacuum to remove dust from the
area. If the filter is unable to be cleaned correctly or is damaged,
then replace it. Pull the air filter from the projector and place the
new one in the now empty slot. Close and secure the air filter cover.

Purchased our76C in Jan, 2007. It is our second unit now that has had the same symptoms. When the unit starts up, the Power light is steady green as normal for a few minutes, but no image is projected. After a few minutes the lights do as you described. Both times Epson support authorized a new unit to be shipped out immediately. They said they had no known issues about it and didn't indicate what was causing the problem. Apparently it is not just the lamp wither. Also, the lamps both had under 20 hours on them.
