Question about BenQ SP831 Projector
Every component works, but the projector won't finish initialization when switched on by powering the lamp. Lamp can be powered manually by pulling lamp-on signal to ground, but then a lamp error code "fan initialization error" shows. Also forcing power on the fans using fan signals won't help with the error.

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.

You need to replace the balast as the voltages are buringing the bulb out and this is caused by a balast that is bad. The baslast is what the bulb connects to this has a sensor on it that relays voltages and heat back to the main control unit.
