    Benq Q9T3 - fix

    Hello,

    Just wanted to share some photos of some nasty caps on a Benq T904 (Q9T3). Replaced all leaky caps, and everything is good again!

    Benq Zowie XL2540K / Power board failure / 6Pin-SOP-Chip identification
    by seppde
    Hello everyone,
    I've got a Benq power board of a XL2540K monitor which suffered from a power cut and is since defective / won't turn on. It's got obvious defects, some blown resistors, some burning around the drain pin of a MOSFET...
    ... and some 6-pin IC I struggle identifying, that is driving said MOSFET.
    The IC is labeled as IC601, so someone with a circuit schematic could probably identify it really quick, unfortunately I can't find the schematics.
    In other power boards of Benq for which I did find the schematics, IC601 is an 8-pin NCP1200 PWM controller - I suppose...

    BenQ TH681 Originally overheating now wont fire the lamp - Colour wheel not starting
    by AJ847.63e
    Hi All.

    Does anyone have any reference materials or something I can use to try troubleshooting a BenQ TH681? Google unfortunately has turned up zip. I did find a service manual for a W series BenQ but that is pretty much useless, it's more a glorified user manual. A list of voltages would be great as I suspect my mainboard is faulty, the colour wheel voltage is not dipping like it should.

    The one I am troubleshooting now was originally overheating after a lamp replacement. It originally would take 2 minutes or so for it to shut off and blink the temp and lamp lights...

    Hi!

    I am new to this site, and found it via LLM ChatGPT.

    I got a BenQ Ex3501R monitor which i have had for a while now, it works pretty good until recently, it struggles to turn on, i can see the purple welcome screen is shown for a brief time before it vanish again, usually it stays on for a couple of seconds before the main computer screen is shown, but image is still kept black, before i just had to turn it off and on a few times and that would leave it on, but now it takes ever longer to stabilize the image on the screen, ocasionally i can see the computer desktop...
