Your projector needs little maintenance. The only thing you
need to do on a regular basis is to keep the lens clean. Never remove any parts of the projector except the lamp.
Contact your dealer if other parts need replacing. Cleaning the lens Clean the lens whenever you notice dirt or dust on the
surface. • Use a canister of compressed air to remove dust. • If there is dirt or smears, use lens-cleaning paper or
moisten a soft cloth with lens cleaner and gently wipe the lens surface. Never rub the lens with abrasive materials.
Is it really the lens that has dust or the projected images has many tiny dots that grow in numbers? If it is, it must be what technicians call bubbles. This is due to improper uplugging of power cord while the unit is still automatically cools down. The electricity stored in some capacitors goes back to the part of the lens which produces those dots they say. I have the same problem too, and the whole module of that damaged part needs replacement.

SOURCE: dust inside lens...
this can be a doozy, but if you are up to it, remove the top cover, you may have to remove the rear, front and maybe sides, i don't know, but what you are after is the cover over the top of the lens. take that off and use air to blow it out--don't touch anything, just blow. several bursts then quickly replace the cover over the lens assy. if used in a dusty environment or ceiling mounted, you may have to do this as needed.
