Hi;

I have an Infocus IN2114 DLP projector which I bought about 1 year ago. It has started showing with a number of small dots on the screen.

Does anyone now where I can find a service manual for this projector. I need to determine if they are being caused by dust or something else.

You do not need a manual to check & clean the lens outside surface.
If it has mold on the inside surface you will be better to get it serviced by a pro.
They are difficult & delicate to service.

I forgot to say it is most likely mold on the inner surfaces of the lenses.
If you look closely it should be visible.
This often happens to camera lenses too & unfortunately replacement is cheaper than cleaning service in most case for lenses.
If your lense only can be replaced that would be the cheapest option in the case of internal mold or debris.

If the dots are points of different color lights, these are "stuck" pixels on the DLP mirrors - some of them are no longer moving in response to display commands.  Dust on the lens would be completely out of focus; only dust on the chip itself would show up distinctly on the screen, and it would tend to be very irregular.  Stuck mirrors are not fixable; you would have to live with them, replace the chip, or get a new projector.

Spoke with Infocus and it is the DLP chip.

Thank you.
