Question about Optoma H31 WVGA 480P Native EDTV DLP Projector Multimedia Projector
Hi, If you have tried other video sources & still get the same results. It sounds like the motor that turns the color wheel is going bad, These motor's run from 5,000 to 10,000 rpm depending on model & are usually the first point of failure in a color wheel based DLP projector, If you don't count the lamp.
Overtime it may begin to make a squealing noise. Usually you can find replacement motors on the internet by searching the part number printed on the motor google is great for searching part numbers.
