SOURCE: No light come on from the projector

Thats the projector telling you that you need to replace the lamp. Lamps usually lasts for about 2000 hours so if you had it for a while you may need to replace it.

www.froogle.com and enter your make and model or go to www.projectorcentral.com and find a few retailers in the US that sells lamps.

good luck

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!

SOURCE: Benq pb6100, light bulb does not on, power ok

I fixed the exact same problem on my PB6200. Both back fans were not working, and the bulb would not turn on.

In my projector, the fan board had a bad capacitor. The fan board is the one where all 3 fans are connected, and which is facing upside down on top of the powerboard. The bad capacitor on my projector was coded C7302 on the schematics. It's a brown, 25v 470uf capacitor.

I recommend you to open your projector, unplug all connections to the fan board, turn it upside, and inspect the capacitors and other components. Bad capacitors have a bulge and/or a black stain or fluid coming out on the top. You can find pictures on the net.

Benq w1000 project not turning on


Look at the manual page 34, for the indicator messages. I suspect it's the same problem I have (which I haven't had formally diagnosed yet!), which I believe is a defective fan. My projector had been making a really loud noise on startup, which varied in length and volume. Recently the projector has taken to turning itself off after being on for about a minute, and the power light flashes green, with the temp and lamp lights flashing red.

My Benq PB6100 shut off after a few seconds


I had the same problem.
First thing to do is look up the owners manual, unless you happen to still have it, then verify the the sensor for the second (or rear something that sounds not like first) temp sensor is going off. If it is basically the fan that sends air into the lamps compartment may be clogged. I have had mine for several years and recently had the same problem. I almost went out to buy something new until I convinced myself that there was no harm in taking it apart and trying something. Good thing too, since all I had to do was clean the fan and reassemble. After that it stopped turning off by itself and I haven't seen any red lights.
Good luck to You!

Benq PB6200 projector lamp or other problem


Hi there

I replaced a Mainboard on a BenQ PB6210 just yesterday - had all the same symtoms.

No LED lights coming on but the rest of the buttons has light.

Tried every other component from the lamp to the colourwheel , but the Mainboard replacement fixed it in the end.

You'll be looking at about $95 for the part
