Question about BenQ PB7230 Multimedia Projector
Our church has the Benq PB7230 that is blinking the lamp indicator but after changing the bulb it still blinks. Any ideas? We recently had a t-storm go through, but everything was unplugged before the storm. Not sure what to check.

I don't have the manual on this one, but in general if the lights indicated that the lamp needed to be changed because of hours of use, then until the lamp hours have been reset, the lights will remain. The owner's manual should have the procedure for resetting the lamp hours. Try that and update this if you still have a problem. Also, check to be sure that the lamp access door is closed completely. There are safety switches that get activated when the door is not installed correctly.

SOURCE: LCD shutting off automatically
Had the same problem with PB2140, during startup the lamp went off and power and lamp leds turned on. This happened after the projector fell down. I read a post there hat mentioned it was probably the power supply so i disassembled the projector. I found out that a small transistor of the power supply was torn away but it was still inside the projector. I found it, put it back and the projector works just fine. Thanks!

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
