Sharp Data Pro Projector (PG-D2500x) in Stand by

[troxel]

The projector was working fine and suddenly the next day would not work. The power light and lamp light blink green and the projectors sounds like it's starting up but then goes into standby mode. The lights blink many times, and eventually both will turn red.

I have two projectors and switched the bulbs around and get the same problem. (The donor projector works fine with the other bulb, so I believe that would rule out the lamp?).

Any help or suggestions would greatly be appreciated.

Thanks!
