Question about BenQ (200NSH-LAMP) Projector Lamp for PB6100, PB620

1 Answer

Benq PB6200 projector lamp or other problem

I have had this projector for 3 years. Twice this last month it turned off on its own. (no bad lamp warning yet) Two days ago, the projector turned off again on its own and the red light indicating a bad lamp came on once for the first time. I turned off and on the power switch from the back of the unit. Now, when I turn the power switch on, instead of causing the power green light turn on on the console, and the bad-lamp red light turn on too (assuming the lamp is bad), nothing happens. (There is only a green flushing barely visible not on the leds but on the buttons of the console, as if a malfunction problem is happening.) How do I figure out if the lamp is bad (I removed the lamp and no black/smoky areas are visible) or there is something wrong with the unit. I see no point replacing the lamp on a broken unit, but I have read that sometimes units behave abnormally in the presence of a bad lamp, and replacing the lamp fixes the problem. Thanks!

    PB6200 fan running but no light. Three LEDs (power, temp, lamp) all off. Only way to stop fan is to turn off power switch or unplug. Any suggestions??

    i have almost the same problems, my projector not running at all, i think. i send it to the shop but he charged me for $250 to replace the main board. I am so disappointed, i don't know what to say, i ask the shop to figure out whats wrong but he still not sure and keep insisting me to get ready with the money in case he replace the main board, this happened early this year.. until now he haven't call me back, he said that he is still figuring it out. what am i going to do?

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

The fans are on all the time, no light though, the buttons on the unit do light up. Would this be the lamp?

Your correct about missing your primary color. this could be either your cable or the connection at the projector could have a bent pin on the port. not sure what your trying to display computer?

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."

Flickering dots on Benq PB6200 projector.


it's not the lamp. if you've replaced the cords and still have the problem, reset the settings to factory default to make sure the resolution matches. if still not ok, there may be an issue with the main board.

Mine needed a "fan module" replaced. The part number is 60.J8613.011.

Cost was $60, plus $100 for labour.

Mainboard of PB6200


Hi, I'm looking for a mainboard too. Just last week one of the PLL clock multipliers wacked-out and overclocked one of the DLP ICs. (confirmed by O-scope and service manual). Guess they timed the warranty just right before the units start to die.

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.
