    I have a Maxx Maverick projector and it shuts down automatically after a few minutes of use.  I have used this projector for several years without any problems.  The bulb still has at least 1000 hours of use left.  Once it shuts down, there are no lights indicating that there is temp problem.  There is nothing in the manual relating to troubleshooting this issue.

    I have the same problem. The projector cycles on, picture goes to black and shuts off. I have maybe 500 hours on this bulb. I have tried disconnecting power, reconnecting cables etc.

It's not a short, the blub is near the end of it's life ~ the optoma is designed to detect when the blub is about to blow and shuts itself down. Turning the projector upside down or right side up usually only gives you a brief reprieve (some have reported a modest amount of extra time gained) on the blub ~ but in the end it's on it's way out and the projector will shut down again.

You have a blown bulb. I have the same projector and it had the same problem. The bulb is blown replace it and you should be fine.

If you are not sure of my solution you need to know that your projector will look like it is starting up and the bulb will partially light up but never come up to full brightness, then the projector will shut down. This will happen over and over until it just gets to the point it just turns on (the fan comes on and then about 30 - 60 seconds later the fan turns off.

Replace the bulb and you should be fine.

Been there done that!

I had this problem as well a year ago, but the solution was in reverse. I mounted it on the ceiling to "solve" the problem. But, no matter what I did, it would not run on desktop. Now I am experiencing the same problem from the ceiling mount position, and it still does not work on desktop. So it looks like I will have to take it to a repair shop to test for this mysterious short.

I had this problem too. I googled for similar problems and found a solution that worked for me. My projector is ceiling mounted upside down. When I turned the projector over so that it was right side up and started it, it worked fine. I ran it this way for about 1/2 hour then reinstalled it upside down. Problem solved. I suspect there is a short somewhere that only occurs when the projector is upside down. I had tried everything else first, i.e. reinstalling the bulb, cleaning with air etc.

I have an optima h56 and when I turn on the power it acts as though it is trying to come on and then shuts down, and I do not see the light coming on from the bulb.


it's either the colorwheel, or the ballast. do you hear a high-pitched whir? if yes, the problem is the ballast. if no, the colorwheel.

Cooling fan problem projector


I have a similar issue though mine isn't quite as extreme as yours. Got a couple things you can do.

1. clean out the projector with compressed air. You might have dust building up on components that is trapping heat.

2. Your fan might be burning out. Needs to be replaced. I'm still working on trying to figure out what tipe of fan it needs.

3. The temperature sensor might be going bad. This one is less likely and most complex to solve as it depends on how the system measures the temp. I haven't checked in detail yet.

4. Replace the whole unit or send it in for repair. Both options will be costly...

Dramatic increase in fan noise


Hi there

If you place your hand on the machine and you can actually feel the vibration , you might be looking at a faulty Colourwheel.

If not , try cleaning the fans by blowing it out. If the problem still occurs you might have to replace the fans.
