Question about BenQ PB6100 Multimedia Projector

1 Answer

Any place in canada for a new main board for the Benq pb6xxx series?

I'm in Canada and have the exact problem, well first it was a blown capacitor, which I fixed, but now it's just a white screen. Any sources in canada for parts?

    Sorry, I thought this was going to quote another question asked. Here's the rundown..... My projector (Benq PB6100) has always been in standby. One day I walk out and hear the fan going on it, which is weird because it is in standby. Just the middle fan was working and the back two weren't. So I opened up the unit and found a bulging leaky capacitor on the fan board and replaced that.

    Now everything works, but all I get is a white screen. I did take pretty much everything apart, including the optical unit. I'm wondering if I didn't put it together right, or that whatever blew the capacitor, also blew the main board. Any thoughts? I don't want to spend $600 on service for a unit I can buy for $650 on ebay.

    Thanks in advance,
    SM (Canada)

    Hi there, thanks for replying. When I disassembled the first time, I didn't take the DLP chip out of it's socket, so it shouldn't be upside down. The second time I took the projector apart, I did take it out of it's socket, but tried to put it back in the same way...and got he same result so I must have put it back in the same way. I've checked the connectors about 10 times now, so that shouldn't be the problem either. No weird smell either.

    The input board is the same as the main board and it seems fine as well. How much do you think it would cost to have someone just look at it, then replace the main board?

It's a reasonable possibility the main board is blown. Lets make sure it isn't. When you disassembled it did you make note of the orientation of the DLP chip? This is an important part as it needs to be clean and in the right orientation. Also are all the connectors seated correctly, does the main board smell like eggs or sulfer? What is the condition of the input board? If you can have someone look at it, it could be cheaper than you think.

I had the exact same problem, I followed the advice of Victorbello on this site, and found a bulging capacitor where he suggested to look. Read where below.
I soldered in a new one from Radio Shack ($1.50) and the projector works again.
PB6200 symptoms: Back fans were not working Bulb won't light (but is in perfect condition) LEDs on control light, but not three status LEDs Internal fan will not turn off.
Solution: The mainboard had a bad capacitor The 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 a 25V 470uf 10mm diameter, 16mm high, 5mm lead spacing 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."

Is there repair documentation for the BENQ PE8700? I am interested in repairing the color wheel but have never done this before so some step by step instructions would be welcomed.


remove the top case. the colorwheel is located between the lamp and the lens. remove anything on top of it. unplug the ribbon cable from the main board. unscrew the colorwheel mount. replace with the new one. plug it in and reverse the directions. just remember where the screws went and all of the plugs you unplugged.

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.
