Question about Optoma HD72 Multimedia Projector
My machine is 3 months old with 970 hours on the bulb. The bulb turns off after 30 seconds, no LEDS. Machine keeps running. I've tried repowering, removing bulb, same problem. Thanks, Mike
Just so everyone knows, This projector is notorious for the iris going bad. Which causes the projector to just shut off randomly. You will have to send it in for repair.

My Projector is 6 months old and now it does not power up. When I press power switch on remote, the projector fan starts and red Led Blinks, but after a while the Led Become Solid Red and fan is switched off. No Picture comes. What could be the problem?

This is NOT a bulb problem unless your "lamp" LED is lit, which you say it is not. Many people have reported this problem with the Optoma 72. You can send it in for warranty service (it has a 2-year warranty) to get the lamp controller chip replaced, but the problem may recur. Optoma does not appear to have a permanent solution to this problem. My projector has broken exactly like yours TWICE in a year. I haven't even needed to replace the original bulb yet. :(

Same problem for me 16 months old, 1100hrs on bulb still under warranty.
Unit shut off after approx 90 seconds.
It continued to do this for 6 days straight.
On the 7th day I wiped the projector lens clean and have not had a problem for past 2 weeks.
I am a smoker so I am guessing the smoke build up on lens caused heat build up that triggered the shut down.
I will continue to wipe the lens before each use.

This is what the bulb does at the end of it's life. After replacing my bulb i have had no more problems. You can try to get by until your replacement bulb arrives by restoring to factory default settings. This will put you back into economy mode. This got me about a weeks time.
