Re: Focus

If the focus motor does not work, the motor could be bad. or because it is an lcd projector, it could be the fly-eye lens or the light filter is singed and need replacing. also try matching resolution with source.

Infocus 3916 Projector goes in and out of focus. It is a little less than 2 years old. Any suggestions for a solution?

Many of these projectors have a manual focus, and an auto focus. Make sure the auto focus is turned off in the menu options.
Then make sure the manual focus is not moving on it's own from vibration of the cooling fan. You can check this by manually focusing the projector, then taking a marker and marking a line on the focus wheels. If the projector goes out of focus, check the line you made and see if it has moved, if so. Your projector is going out of focus from vibration of the cooling fan, or the surrounding environment.
If your projector is mounted to the ceiling you can add a couple of rubber washers between the projector and the mounting bracket to cut down on vibration.
If your projector is sitting on a desk / table / ground, you can use foam padding to keep it from vibrating.

another solutions would be to temporarily tape the adjusting knobs while the projector is in use.
If your projector has a protective cap that is put on the lens when not in use, this will also push the lens out of focus, and will need to be re-adjusted each use.

DP9270 will not focus after bulb replacement.

I see two possibilities:
1 The new bulb is a different size (glass part longer or shorter) than the original.
2 The bulb is not fitted in the socket correctly.
Both of these situations will place the actual bulb filament closer or further from the focusing lens, hence out of focus.

Projector wont focus

Not menioned the make/model of thsi projector. please check if the LENS settings have changed in aligment or there is any mechanical fault on the lens movement. If so the focus will be lost as the lens have to move around to set for the distance on correction of the display unit.

There are blueish-purple crystal-like distortions in the projected image. They actually can be brought into focus to look at, and at that point the projected image is extremely out of focus. So, obviously,...

either there is something on the inside of the lens, or there is something on the lcd prism face. if it was the lcd panel, it would be in focus with the picture. take it in for a good cleaning.

Sounds like focus is out. These projectors are like cameras; they have an optic with a focus ring. Try rotating the focus. Some have electronic focus as well. If the manual focus does solve the problem, look through the menu for a focus setting adjustment.
