The DLP chip is going bad. You are better off buying a new projector.

Vivtek d510 projector has black and white spots covering 1/3 of projected image


The DLP Chip is failing .The DLP or Digital Light Projection Chip contains up to 8 million tiny microscopic mirrors that tilt to project a digital image onto the screen. These mirrors are failing causing light and dark spots to appear.Unfortunately fixing this projector is probably going to cost more than buying a new one. Hope this helps.

Mitsubishi flickering white lights on screen


this sounds like a bad optical light engine, the spots will only continue to grow in number.

See typical engine for this brand, lens on left is where image comes out and is directed on the screen.

THere are an increasing number of white spots (damaged pixels?) on the projection screen. It started with one, and one flickering, now there are 4 clear spots, and another flickers. Can this be solved?


If the spots are well defined rectangular shapes, then DMD pixel failure would most likely be the problem.
You could replace the DMD chip, but it might be more economical to sell the unit as is and buy a new one

Dark spots on screen on DLP when screen is white


What size are the spots?
If they are 1 pixel in size you have stuck DLP mirrors.
If they are larger not symmetrical then it's most likely dust blobs in the optics near the focal point (on the DLP chip glass window)

I GET WHITE SPOTS ON MY LCD SCREEN


this is a touchy subject for sony. basically sony has increased the brightness levels for the backlights to have better color tones in thier lcd's. well the downfall of this is the white spots you are experiencing. this is not a defect, you will never get them to go away, the only thing you can do is to turn the backlight and brightness down to reduce the white spots. if you contact sony, there is a software upgrade that will help reduce this issue...

One of the pictures has a great blue sky but the green tree is very dark and the other one has the green tree and very bright sky?


The two pictures were shot at dramatically different exposures - the "dark" one at 1/1600 shutter speed, f7.3, the "light" one at 1/320 shutter speed, f4.0. This accounts for the great difference, as the exposure conditions for the "light" one allowed much more light into the image during the exposure period. You didn't tell the whole story of how you set this up, I think you were shooting in a "spot" metering mode, where the particular exposure conditions the camera uses would vary considerably whether you were aiming at a dark area (making the picture light) or a light area (making the picture dark). I would make two recommendations: Switch your metering mode to "center weighted" (the mode labeled "[(•)]"), and also change your ISO setting to AUTO, as there would be no reason for shooting these photos at ISO 200 that I can think of.
