Projector powers on but bulb doesn't light up. Changed bulb, still doesn't work. Tried original bulb in other projector, works fine.

Probably the lamp

Check the internal power and lamp fuse. Sometimes, when a projector is stored, an area of corrosion develops around the lamp pins and lamp holder. If you carefully clean both the holder and the pins on the original lamp you may find it works OK!

the lamp units should be properly aligned with the 2 very tiny switches
between them. If not lamp led will blink.
If lamp led is continuously on, lamp timer has to be reset, according instructions that come with new units.
Original lamp modules are AH-45001 and AH-45002, two different
units needen for 1 projector, reset procedure is different for each lamp !!

If you are sure that you installed the new bulb correctly , then I recommend that you reset your projector . Some projectors don't realize that you changed the bulb physically until you reset them .

please rate !

reset the lamp and filter timers. turn the projector off then back on.

The projector bulb was burned out.

when You changed the bulb  you have to reset the bulb timer , that why the light is flashing red , look at your manual and reset the timer , and the picture , changed bulbs myself before i found what the problem was , 

we were unable to pull the projector menu & it also took about 2 hours for the bulb to turn on.......the fan works, have changed the bulb, closed the bulb door & tried to reset the projector.......help!

The Projector will turn off after so many hours of running the same bulb module. The counter will turn on a replace bulb LED. Installing the new bulb module should reset the counter and turn off the LED.

Check the projector’s lamp to ensure that it is securely connected
in the lamp module. Make sure by removing it and reinserting it.

Check the cables for problems.

When testing, power up in this order. Projector, Computer monitor, Computer.

A minor power surge may cause the lamp to shut off. Turn the
projector off, wait at least 30 seconds, then turn it back on.

I hope these suggestions help
