SOURCE: Optoma hd65 projector new bulb wont turn on...cant reset timer!

I think it's a lamp driver issue from what I've seen others have gone through. I also read that if you go through the sequence of unplugging, plug back in, wait 20 seconds and try to turn on, multiple times, it will finally kick on and work. I just got mine to turn back on by doing this and waiting through the fan cycling without the light turning on. After the 4th sequence the light flickered. After the 7th sequence it finally turned on and is working. Now I can watch the Super Bowl and will look into replacing soon.

I have an optima hd180 that will not power up. The projector was indicating a bad bulb, so I replaced that with a new one. Now it still will not power up and the fan does not come on either.


Problem w/ OEM bulb, it causes a lot of issues from my experience. Your ballast might have gone bad, hopefully it's just that. Check the voltage output of the ballast, make sure you're getting the proper amount.

I have an Optoma EP716 projector. It has run for


either the lamp has/is going to expire, or the ballast is bad. if the lamp has bulges or black spots on the inside, replace the lamp and clean out your projector with canned air. too much dust keeps in the heat and makes a 2000 hour lamp go in 1100 hours.

Optoma HD65 bulb only 108 hrs old having difficulty starting up


Use the warranty! since you anly had it for 8 weeks, and the waaranty last for one year, go back with it and get it repaired or get a new bulb. A buld last at least 2500 hours, in eco mode it last for over 3000 hours.

Good luck to you

Flasing red light


The flashing red indicates that either the fileter cover or the lamp cover is not installed correctly. If both are installed properly and secured, the unit will require service.

Lamp light on picture off


You might try unplugging the set for maybe 20 mins. to see if that might help in resetting the internals. Good luck!
