Picture starts off in colour then turns to black and white after around 10 minutes. all the while it is full of white specs allover which seem t increase as time goes by.
From my experience repairing projectors he problem is the DMD CHIP is bad. In short, the DMD chip or DLP chip has thousands of tiny mirrors that turn on & off in a twisting motion to reflect the image onto the screen. What happens is the DMD chip breaks down do to high heat , wear, and bad manufacturing. Unfortunately, the DMD chip has to be replaced & it's usually but not always a pricey part. If you need a replacement part or would like it serviced for you I can give you a price for either service. Pls contact me with your name, make & model projector & what the problem seems to be & I'll give you a fair price for a used or new part or repair.

i was thinking there is a problem with the colour wheel, maybe as it heats up ( environment right now is 46 degrees celcius) something goes wring with its motor. i have tried leaving the fan on directly but it did not seem to help!
