There is a very picky sensor on the lamp cover. When the lamp and cover are seated perfectly, your lamp will start.

    How do I find the sensor and ensure it is engaged? I have the same problem with two projectors, after numerous lamp change attempts with a number of new bulbs. They can't all be duds.

    Additional info: The projector acts like it is going to work. The blue light around the on switch is illuminated.the fan runs, and about a minute later, the defective lamp indicator illuminates.

I replaced the lamp in my sb21, but now the right side of the projection is dark. left side is clear and sharp but starts to go dark about midway across. Could the new bulb just need to be cleaned?


Try taking the lamp out and reinstalling it - it may not be all the way in. If this does not help, a polarizer or filter may be bad. It's going to be hard to get replacement parts for this old projector that is at least 11 years old.
The only other thing I can think of is to try a factory reset - look through the menus until you find this.

Hp sb21 out of sync


Are you simply feeding the projector with a video signal outside the range the projector can accept? For instance, trying to feed HD video to a projector that is not capable of high resolution can produce an out of sync image - or nothing at all.

I assume you've tried using a different video cable to connect to the projector, just in case there is a broken core in the original one that carried the sync signal?
