If your comfortable w/surface mount troubleshooting and soldering,
download the service manual from elsewhere online. Part of the
troubleshooting tree for this type of problem is to check the surface
mount fuses on the underside on the Main PWB (schematic page 1/8). On
mine, the 12V surface mount fuse, F3004 (2.3A) was open (quadrant C1 on
the schematic). Replaced it, reassembled the projector (3 interlocks
don't 'cha know) and it came up just fine.

Have you resetted the lamp timer ? It must be done when a new lamp is inserted into the unit.
You can reset the lamp timer by holding the up arrow key on the Projector in until a online message appears. Then just follow the on-screen instructions.
If the problem persists , you will have to replace the Ballast wich is the lamp's power supply.

The reason why the projector is shutting off is so the lamp doesn't explode. It's more of a safety feature on the projector, you can reset the lamp and it might work for another 500hours. If the picture is still pretty bright I can get you the reset procedure, but be warn that when the lamp does eventually blow it could shatter the glass inside, so be careful, it shouldn't hurt the unit.

With power available at the projector and the lamp off (projector off) - hold the input button on and press the power button on and hold for 5 secs. This will reset the lamp timer to zero.
I wish they could have stuck this in the operators manual.
