Optoma HD65 flashing colors

About a month ago, our projector started flashing colors. We replaced the bulb about 2 weeks ago and it stopped. But, today while we were watching tv, it started again. It flashes mostly red and green and will be really quick,...maybe once or twice every few minutes. any suggestions on what this could be?

    I have the same problem with my Optoma HD32. The issue is intermittent, sometimes won't happen for quite a while, sometimes frequent flashes over a short time period. Doesn't seem to matter how long the machine has been on. Color wheel issue? We recently also had persistent horizontal bars on the screen, but those went away right about the time the color issues cropped up.

Possible cause is overheating.
Do you hear the fan working?
What happens when you use the lowest level light output?
Does it run longer?

Also possible cause is a faulty temp sensor.
AC wire connection may not be firmly pressed in socket.

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.

Sounds as though the system may have overheated. Do you regularly check the filters and clean them? An airduster can also help to blow dust out of hard to reach places.

My cinego shuts down


There are two fans on the right side. If one stops working, the Cinego will have the symptoms you have described. You need to send it in for repair. A local Radio Shack will tell you where to send it.

Degrading picture with my Dwin projector


the colorwheel is going bad and needs replacing. the colorwheel needs to spin fast enough to sync up with the dmd chip. if it cannot, the pic goes bad then off. the flashing is the colorwheel trying to catch up.
