Hello, I know this topic has probably been covered ad nauseam in this forum, but I'm new here, and a simple google search has less results; so if I'm being repetitive to past posts I apologize to all the veterans in advance.
When I put the projector in "blank" mode I can see the blobs quite clearly; this is the same as a very dark (or nearly black) scene in a movie. Now, when I defocus the lens totally, the blobs sharpen up and look like a starry sky (there's quite a few of them, but only the biggest ones show up as blobs in focusewd viewing; I suppose others may decrease contrast or something but this is not noticeable enough to be annoying).
When I stare into the lens at an angle (even in blank mode, the light is quite bright...) I can actually see the dust particles.
My question is this: Am I seeing dust stuck to the reflector mirror? That's what it seems like; BUT:
In out-of-focus, the "stars" also show outside the black square of the projected image, SO - does this mean I also have dust on the back of the lens.
AND FINALLY: Is the lens assembly airtight? can dust enter INSIDE between the lenses?
The projector is just 2 months old and within warranty. I am quite technically minded (I'm a watchmaker) but prefer to take it to the service center to fix. But if this problem will recur (I live in a dusty area, near the desert), is it very dangerous/difficult to clean on my own? the service center is a good one-hour drive away.
And also - are these things normally covered by the warranty? specifically in Viewsonic, I mean. Does anyone here know?
