Sound like the original color wheel for Optoma HD80 is bad.

If the unit has been moved when hot.

If not, try un-plugging the unit for a few minutes and re-connect.

Hope this helps

Light of projector is not working


Try to turn off your projector and open it again after 10 minutes. The lamp may be malfunctioning due to overheat. This usually happens when your projector was not turned off properly. The fans inside the projector should slowly cool the lamp inside when turning it off properly causing the projector to be in a standby mode for a couple of minutes before you can completely unplug it.

The lamp cover has a disconnect that wont allow the unit to power on while the cover is off.

Try taking the lamp cover off and bending the little piece of metal you find underneith.

It worked for me.

I've had the same problem with my projector three times (usually whenever there's a sports championship). You just need to call optoma, get an RMA number, and ship it to them. Theoretically they'll fix it under warranty and send it back free.
