    FIXED: Benq FP767 won't power up

    Hi. Just posting to say thanks for all the useful information I found on this forum.

    My Benq FP767 monitor wouldn't power up. No signs of life when pressing the ON button.

    I checked the mains input then had a look inside. The case is quite difficult to remove, As well as unscrewing the pedestal and all the obvious screws on the back, you have to lever open lots of plastic latches along each edge. I worked carefully starting from the corners and levering with a blunt knife, but I still managed to break a few of the latches. It's obviously not designed for ease of opening.

    Inside you have to separate the electronics chassis from the LCD screen and disconnect all the connectors. Then you can turn over the metal chassis and remove the two PCBs inside. They are linked with a plug and socket and have to be removed together.

    I found two bulging capacitors branded Elite, which I replaced.

    C707 1000uF 35V
    C710 1000uF 16V

    Miraculously it worked straight away. Thanks to everyone on the forum for helpful information.

    Acer Nitro XV273 and Predator XB273, look inside and disassembly guide.
    by Flaku_34
    Introduction:
    Hello everyone, this topic is more of a knowledge sharing and look inside type of post, but for someone working on this model of display it might be useful. Recently I bought Acer Nitro XV273 XB MIIPRZX with busted electronic, but screen was intact, price was incredibly low, so I took a gamble and bought the unit and try to fix it. As I dug inside, I found out that my motherboard was not responding, although all voltages seemed fine. I wasn't able to find any reliable information about this monitor on the web (only some pictures of motherboards from Ebay). By some research...

    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...

    Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel
    by howardc64
    Failure Symptom



    No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

    Where is the short?

    Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.



    Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but...

    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...
