Hello!

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.

Unplug any cables from the projector (except for power)
On the device (not the remote control) hold down exit for 3 sec
lamp status are shown
on the remote control use MENU, and then left right to reset lamp

SOURCE: Lots of details: LP120 stays on for a minute, then powers off

either the colorwheel motor is not getting up to speed to sync with the dmd chip, the wheel sensor is going, or the power supply needs replacing. you can try to replace them yourself or send it to an infocus authorized service center. try www.avsolutionsny.com . they're pretty good.
