1. check your lamp---take it and look into it and see if you see any cracks or bubbles in the mirror part and try and look at the stem IN the mirror for any bulges that might look like a vein about to explode---if so the lamp is bad.
2.next you need to make sure all fans are working.
3. if it's not the lamp or the fans, then it goes-power supply, main board.

SOURCE: Projector shuts off after about 45 minutes

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.

What could be the issue if my projector turns itself off after only running for 1-2 minutes?


It maybe a problem with your lamp as they can run for a short while then shut down.
When it shuts down do you get the lamp or temp indicator coming on?

Epson Projector, Model: EMP-X5, Epson projector shuts down after 30 minutes work


There are several things that can cause this problem, but the first thing I would check is the filter. The projector requires airflow to keep it cool. If airflow is blocked, the projector will overheat and shut down automatically.
