Jvc zoom not working!!!

Hi, I have a jvc 4910 (same as x500) using a 140inch screen. I was adjusting the zoom today but found that I can only decrease it not increase it, could the motor have malfunctioned somehow? Is there a way to adjust it manually? I've lost a good 10inches since I decreased it a bit to see if it would respond and it did, but now I can't increase it! Please help!

Oh and all the other functions do work, I also tried the buttons on the projector itself.

Sounds like the motor is not working. Motor could have died or become disconnected.

If the engine did not work, then it would be impossible to reduce the zoom.
Most likely a problem with the lens.
In any case, you need to disassemble the projector and find out the reason.

You are right. It would be the same motor. So it is either something to do with the gears or in the board that sends the signal to the motor. You should be able to hear if the motor is running, when trying to zoom and that would narrow it down. I suspect a gear out of place.
