Question about BenQ SP820 Projector
I have a BenQ SP820 Digital Projector. I have it connected using a VGA cable to my desktop computer. It is connected to a Nvidia GeForce 8600GT 512MB GDDR3 video card as a second monitor.
It turns on fine, the loading screen comes on. I can see my desktop on it for a short time and then it shuts off. When it shuts off the fans seem to go into turbo mode and it won't shut off unless you hit the power switch on the back. I read the manual and noticed i am getting an LED error code of:
That code is Fan4 error (Power), according to the manual.
I just purchased this unit like 4 hours ago. It was an unopened box and all pieces were accounted for.

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!

SOURCE: SP820 lamp never comes on. It
18 blinks is not a fault code. The LED probably starts blinking because the controller board is faulty, and stops after 18 times because it dies always at the same time. Problem is likely main controller board, you can try testing the board at component level. Check connectors a shorted connector is a common fault that may have unforeseen effects. Test PSU voltages just in case, wrong voltage to controller may fry it and may result in no error code.
