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...

Why won't my Optoma DV10 projector won't turn on?


On an Optoma DV10 if its not the lamp timer, then it might be a cooling fan that needs replacing. Take out the old one, and look-up its part number online. If you don't feel confident taking it apart, have a qualified person do this.

Projectors shut off when they overheat. They overheat when air does not move through the projector cooling it. This happens when the fans are not working or air filters/vents are not working.
Check to see whether the fans are working. If they are working, open the cover and see whether air filters/vents are covered with dust. If so clean them.

High temp light on when powering up


Remove the screws and check out the fan's working state.
EP759 have one big 92mm fan for the lamp, and three small, near 40mm, fan's for the optics.

Power of the bulb is very high, so just 1 broken fan can make that situation.

Projector shuts down after only a few minutes.


I'm having the same problem. My Model is PB8253. Projector started, then afer a couple minutes it goes off with the red lamp led flashing.
Just replaced the lamp, but the problem persists. Tried to remove all connecting cables, except for the power, but still the same problem.
Anyone with similar problem or solution, please contact me at dartveiga@gmail.com

EP 757 Intermittent powering down


Pls check if the lamp is not so old that is giving the same problem. If lamp is almost new, then you can have a check with the Ballast unit card and then the loose connection in the Power supply or may be overheating and tripping.
