BenQ PB8220 DLP projector - lamp button continues to flash after bulb replacement

My projector recently lost bulb operation and shutdown with the bulb light button flashing. I replaced the bulb and the projector tries to power up but when the fans turn on the lamp button starts flashing and will go into shutdown. If anyone has any ideas or suggestions I would appreciate them.

After 2 years I finnaly solved the problem. There was a flaw in the lamp´s temperature circuit. A technician disassambled my BENQ PB8253 unit and fixed the problem. Charged me US$ 75.00. I´m in Brazil.

Hope this can help.

I have had the same problem about three times over the past two years, I have identified that it depends really much on in which sequence you switch off the projector, esp. if it is connected to another device (e..g amp for home cinema). So first the double press to power off, wait for the fan to cool off (no more sound), click on the on-off button to switch off, then switch off your other device if teh PB8220 is conected to it or a laptop).
Every time I've had the problem (the red lamp flashing after reboot), I've left the projector UNTOUCHED for TWO MONTHS, and it restarted and performed well after that. I know this is a real pain but it worked.

Lamp never fires Unit goes right to cool/shutdown.

The ballast might have gone bad, you'll need to check the output voltage of it. In some projectors, the power supply/ballast are combined as one PCB instead of 2 separate boards.

I've just replaced the lamp on my Panasonic PT-LM2E projector and it will switch on but no light comes out. The previous lamp blew in the projector after around 2000 hrs. The indicators are as...

I'd recommend checking the fans of the projector, and make sure that they're spinning. Since you've mentioned that the lamp blew inside the unit, bits and pieces of the lamp might have lodged itself within the fans. It might also have to do w/ the after-market replacement bulb, which I normally wouldn't recommend.
