    Hannspree HF237HPB Two Second Turns off

    I have read over the sticky and have tested most components that I know how to test, I desolderd almost all caps and tested and tested regulators. When I turn on the monitor of course it comes on but the image seems a bit dim and then it turns off. I'm not sure if I'm hearing things or not but I think I hear an arcing sound as it turns off. I'm thinking that CFL's are the issue, the board looks good but I'm not sure how to test the transformers for the CFL's. I have connected each lead of the bulbs to see if they are shorted to the lcd frame and didn't detect that. I'm just not sure where proceed from here. I don't want to have to take the lcd apart, I hate changing CFL's, maybe it is easier on monitor than lcd notebooks? Any suggestions on how to proceed would be helpful. Also, I have tested diodes but I'm not sure how to test zener diodes in circuit??


    On a side note, since almost everyone here is a electronics guru. Anyone know where I can get one of these ribbon cable SMD connectors? I can't find on mouser but I don't know what I'm searching for. It's a 6pin tiny thing...pictured.

    MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable
    by Stephen
    MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable to reset the computer. I disconnect the battery fully and then reconnect it and it won't turn back on. After letting it sit for a day I plug the battery back up, and the MagSafe 3 cable and it powers on and stays ons, once I plug in a USB C cable into the port closes to the MagSafe port it turns off and the Amber light turns off and won't turn on. No water damage, nothing, I want to do a DFU restore to wipe the computer since the customer stated they did an update and ever since it just decided to not work...

    LG L192WS-BN backlight turns off after 1 second
    by www
    I am testing an old LG L192WS-BN monitor I have that gives an image, but has a backlight issue. When you turn it on the backlight turns on 1 second and it turns off, turns on again, 1 second and it turns off and stays off. Using a flashlight I can see there's still an image.

    I replaced a bulged cap on the main board, but made no difference. I also got another exact same model monitor that has a broken ccfl (the connector got ripped from the panel and the main screen connector is also broken so I can't use this panel to test), tried using the main board from this one, same issue....

    Dell Precision 5510, motherboard AAM00 LA-C361P Rev:2.0
    The board turns on, there is no image.
    Read more. When the power supply is connected, the front panel indicators light up briefly.
    When you press the power button, the button indicator lights up. The board works
    there is no image, there is no matrix initialization, there is no image on HDMI.
    When turned on, the fans do not spin, but when they warm up they start spinning.
    When you turn off the button, the fans spin up to full speed for a short...

    Samsung UE55F8000SZ Turns on and off immediately
    by Egidio85
    good morning, I have a samsung UE55F8000SZ tv that turns on, shows the logo and turns off after 1-2 seconds.
    This defect happens continuously, hearing the classic click of the relay every time.

    Power supply board BN44-00636B

    disconnecting the mains and lamps from the power board always causes the same problem.
    Is it normal that without anything connected this power supply turns on and off cyclically?
    any suggestions on what to check?

    thanks in advance
