This is a dlp projector and has a bad DMD chip. Most models are very similar. Here is a video of a similar repair.

1,the color starts to go out, it become the white and black ,
2,then,the projector running off after only a few minutes,
it is a general issue:the inductor need to be cleaned
Use a cotton swab moistened with alcohol to clean the inductor.
the inductor (Sensing element),is near to the Color Wheel.
the industor : is a black little element,as little as a sesame seed

any questions, feel free to ask me
have a nice day!

I have the same problem. All of a sudden there are plenty white dots all around the screen. As if 1/3 of the pixels are burnt. It cannot be the lamp because it is still as bright as before. It must be the internal screen or whatever. The "Troubleshooting" section of the user manual does not mention such thing.

it is most likely a burned polarizing filter. There is a polarizing filter on the blue light channel and another on the red channel. When black, or other dark colours are displayed, the red polarizing filter is supposed to block ALL of the red light being projecter. If the filter is burned, some light slips through and creates a red tinge on the projected image. If the red tinge only appears on dark images, but is absent when the images is completely white, a damaged filter is likely the problem.

Seems its hard to buy them. Best bet is probably buying a broken projector from ebay and stealing the filters out of it.

Souds like a Dlp projector and the wheel inside broke is what it souds like what happend, I would have this serviced.
