Question about InFocus Office Equipment & Supplies
We have tried switching out connector cables. The lens appears to be in fairly good shape and is not scratched enough to cause issues.
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.

It could be the lamp. I have seen this many times on DLP'S. If the ballast is firing it which is usually around 600 volts or so, then i would say it is fine, and only needs a lamp. Let me know if that helped you. Later Jay

A bit unusual for the projector to stop responding to the remote.
Usually it follows when someone has opened the projector, they forgot
to reconnect the controls from the case top which also includes the IR
receiver. If it isn't that, it could be a broken IR pc board or
bad connection. I've seen that.
The worst case is that the IR controller on the main board has failed and if that's the case, you'll have to live with it as the cost of a new board is very high.

Take off the front bezel, then remove the screws from the lens,pull the lens out and blow it out with compressed air. Do not touch the mirror or magnifier inside. If this doesn't get all of the blemishes, then you will have to remove the top cover and then the top silver part of the engine and blow it out from the top.
