Question about BenQ PB8220 DLP projector 2200 ANSI lumens 1024 x 768 Multimedia Projector
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.
