Question about ViewSonic Cine1000 Multimedia Projector

Open Question

There are Bright spots all over the screen (Dust Blobs?)

When projecting dark images i can see what appear to be blurry dots scattered across the screen. They also appear beyond the edge of the projected image. I have cleaned both the bulb and the exterior zoom/focus lense with no positive results. I believe there is some dust inside the machine that is casuing this but am unsre of how to fix the problem.

SOURCE: Convergence error on viewsonic projector PJ820

your gonna need to get a service manual from the manufacturer and do a convergence alighnment with the on board generator. Unless some unknowing hands have been inside the unit.?? Contact them here at this link Good Luck service.us@viewsonic.com

SOURCE: Image blurry at edges

my dear friend, it appears that you must have opened the 3 lcd screws that are not supposed to be touched, if so then just forget reassembling the same as the convergence would be lost & cannot be manually done
another thing are the polarisers.if excessive dust had accumulated & if you used wrong technique in cleaning then the coating would have come off & you have lost everything , just change the entire lcd block.this costs a bomb.beter to buy a new projector

Double check which menu item you are expecting to find the orientation. It might even be under 'image', 'settings', or its own button not in the menu, Jon.

SOURCE: small white dots all over

If the dots cant be blown off the lens, or appear rectangular in shape when looked at close up, then you have pixel failure. If so, then the DMD chip probably needs replacing.

Bubbles are projected on the screen


I am assuming that the "bubbles" are most prominant when the picture is dark. If that is the case, it is most commonly referred to as dust "blobs". Dust particles get on the lens assembly inside the projector and are just out of focus so they appear as blobs or bubbles. If you can carefully remove the cover and gently blow out the lens / color wheel area with compressed air it should reduce the "bubble" effect. I would not recomend any further dissasembly as it is complex and time consuming and unless your very careful, could end in disaster. Don't forget to clean the air filters either.

Why are dots appearing all over the screen???


Do you see anything from source on the screen apart from these dots? Are these dots scattered & very bright? Either your DMD( Digital Micro mirror Device) or DMD board is faulty.

Cannot focus uniformly across the projected screen. This seems to be more than a focus problem in that some areas of the image seem blurry as opposed to out-of-focus. Also, in what may be a related...


try bringing the screen up as close as possible to the projector and still get a focused picture. check keystone here and also for image clarity. if you still have problems, check for dust or moisture etc in the optics. check the lamp for a clean front surface. clean the air filter also. Try a different image source for differences

When we project to the screen, we are getting spots on the screen - mostly noticeable in dark. We blew for dust and still no change


check if the spots are pixel size dots and not dust. if so then the problem is not dust but dead pixel problems

Blue diust specs constellation like!


If you are seeing the "spots" when a black screen is projected, the problem is likely to be scattering caused by dust on the lens. If you can get at both ends of the lens assembly, clean both sides using lens tissue. If the spots are seen at all times, there may be damage to one or more of the LCD panels.

Please update this with your results of the cleaning.

Thanks,
Dan

Optoma HD72 displays white circles when the picture is dark


Have your projector professionally cleaned. It is dust in the inside optics. You should not attempt unless you are very skilled. if you are going to do this yourself have a lot of compressed air on hand.

Hi there

Sounds like you've got a faulty LCD.

Unfortunately it will need replacement before it will get any better
