Dots on projector screen.

Philips UGO series Mulitmedia Projector LC5231

Everything works fine, but on start up I have few dots that remain black colour on the blue screen, after time these dots seem to multiply until there is substantially more than there was. I'm presuming this is either the lamp or something else?

Any help would be greatly appreciated.

If the dots are pixelated, you have an lcd issue (or if you have a dlp, it's a dmd issue). if it's not pixelated, try to focus the lens on them. if you can, it's dust. blow it out with canned air.

Why are there lots of black dots on the screen?

Those "black dots" are either dirt on the inside of the projector or, more likely, dead pixels on the LCD light valve chip.

White dots on the screen

Need more info. But initial suspicion is there is a problem with your projector.

Are they stationary and always in the same position? You may have bad pixels.

Are the dots there with no signal going to the projector?

What is connected the the projector? Detail the video path - try all the sources. The dots still there and in the same position on all sources?

It is probably your projector.

If some of your sources are fine - the problem might be from a connected source.

Hope this helps.

How do you clean the dust out of the projector, there are particles that look like small white stars on the black areas and black stars on the white areas. Is this dust?

If you focus the image on a screen up close to the projector and notice small rectangular black and white spots, then you have pixel failures.
