Projector shut down after replacing the bulb and wont turn on now

If you have recently replaced the bulb you may need to reset the lamp counter in the projector menu.
If you have not replaced the bulb, the projector may be shutting down due to over-heating. Check that the projector is clear of as much dust and debris as possible.

I've seen this happen almost exactly on a Canon projector. The problem was the bulb. After the bulb was replaced the problem went away.

Please remember to rate this solution to show your appreciation!

It does not sound like resetting the lamp timer is what is keeping the projector from throwing an image. Try walking through the steps of the installation backwards to remove the bulb completely. Then reinstall the bulb again from scratch making sure everything is seated properly. If it powers up again just remember to set the clock back on the bulb.

try reseting the lamp timer and then replace the lamp if it works

firdt off, did you reset the lamp counter? did you clean the dust out of the projector? it may be overheating as well. if the lamp looks ok, you may have just blown the ballast. try projector doctor online.

first, make sure you have the correct lamp. the lamp for the xr-10x-l looks like the xr-10x, but the plugs are different (common mistake). make sure you have the AN-XR10L2/1, not the AN-XR10LP/1. to reset the lamp timer (with the projector plugged in but off), hold down the enter, down arrow, and menu buttons and press the power.

you need to reset the lamp timer. turn it on, and press and hold the left arrow, right arrow, and power button until it resets.

From the booklet that comes with the replacement lamp:

1 While holding down the "MENU" and "ON/STANDBY" buttons simultaneously.

2. Insert the power cord

Not great English, but I tried this yesterday and it works.

It's not a short, the blub is near the end of it's life ~ the optoma is designed to detect when the blub is about to blow and shuts itself down. Turning the projector upside down or right side up usually only gives you a brief reprieve (some have reported a modest amount of extra time gained) on the blub ~ but in the end it's on it's way out and the projector will shut down again.
