    Lg 42le4900

    got this tv in, turns on fine and 5 secs later turns of, had a look inside and see the LED driver board, looks like some of the voltage regs have got very hot,
    markings on the regs are F1 A17
    FOT4N201
    cant find anything with that marking, or what there are.

    cant upload pics, as there is no attach, only web link ?

          Acer Nitro 5 LA-L181p power LED turns on by 5 secs (Short on PCH rail?)
          by Victor Moreira Silva
          Hello everyone,

          I'm trying to repair my old Acer Nitro 5 (AN517-54-55T5). I've already bought a new laptop, so this is more of a learning project. For the experience, with no high expectations of success.

          Well, my decice specs are the following:

          Model: Acer Nitro 5 AN517-54-55T5
          CPU: Intel Core i5-11400H
          GPU: NVIDIA GeForce GTX 1650
          Motherboard: GH51G LA-L181P Rev:1c

          The symptom:
          When pressing the power button, the power LED lights up for about 5 seconds and then turns off. Initially, the issue was intermittent: sometimes...

          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....

          Hi.
          I kindly ask you to help me solve the problem.
          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
