The DLP Chip is failing .The DLP or Digital Light Projection Chip contains up to 8 million tiny microscopic mirrors that tilt to project a digital image onto the screen. These mirrors are failing causing light and dark spots to appear.Unfortunately fixing this projector is probably going to cost more than buying a new one. Hope this helps.

SOURCE: LCD projector spots showing up on the screen

there are light filters behind each lcd panel that determine the color of light going through it. because of excessive heat and dust, the filter tends to burn and cause discoloration in the image. if the image is bluish (cyan), the red filter is burning. if it's yellow, the blue is burning. if it's purplish (magenta), the green is burning. the filters will need to be replaced. unfortunately, many companies don't sell individual parts of the optical engine, so the entire engine might need to be replaced.

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.

I,ve got a red spot in the screen i replaced the bulp but stil have the problem


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.
