Question about Epson ELP-3500 Multimedia Projector
SOURCE: Epson ELP 5500 projectors
Will try and get my hands on a Service Manual for this model - in which you would find the circuit diagrams. This is a faulty Mainboard that is causing the problem.

Just a long shot, but...
I have an epson 9000i that did the same thing. Turns out that unit has a small fan (I think 60mm) right next to the power supply to keep it cool, in addition to the large fan that exhausts past the lamp. The fan runs non-stop as long as the unit is powered-up for two reasons I can think of - keep the power supply a little cooler, and the lamp a little warmer so there's not such a temp difference when it powers-up. Long story short, that fan had died. I replaced it with an aftermarket 60mm fan and it's been working fine ever since. Hope this helps.

it appears that one of the cooling fans in ur projector is jammed or not spinning at the required speed!
ope the projector & observe the fans as u switch on!!!if the fans seem fine, then it could be a defective thermistor!

SOURCE: EMP-X5 will not turn on
make sure lamp door is closed and any filters are in. there is also a fuse on the power supply board that may have blown. other than that, the power supply itself may be bad.
