return the projector (still under warranty, if bought new). if it's used, reset the settings on the projector to factory default. if still nothing, replace the remore.

SOURCE: Optoma EP719 settings?Colorwheel? Bulb?? Cable?

take the lamp out and shake the projector gently and tilt it in all directions and listen for something loose near the front of the projector. if you hear something it could be the light tunnel has collasped or the colowheel has lost its segments.

Optoma H30 Projector: color banding


Most DLP projectors have a colour wheel. It's usually hard to get at, and you may have to actually remove everything including the optical block from the projector to access it. This wheel turns on a motor just like a fan, and if it gets dirty it can act up just like a fan.

They are expensive to replace, so you might want to try taking it apart and cleaning it out. Add a small amount of 3 in 1 oil to the motor if you can.

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.
