    LG 55EC9300-UA turns on clicks and turns off

    Once again I need to ask the groups help. This TV will turn on for about two seconds with no picture and LD11401 lights up then the tv clicks and shuts off. The voltages at P201 to the main board are as follows starting with pin 1. All voltages drop to zero after briefly coming on.

    Pwr on is 2v
    3.5v is 0
    3.5v is 0
    G
    24v is 22v
    G
    12v is 10v
    12v is 10v
    G

    Drv-on is 0
    DPC is 0
    3.5v is 0
    G
    24v is 23v
    G
    12v is 12v
    24v is 23v
    G
    Any help would be appreciated as always.

      Powersupply has all the voltages - Monitor still no power
      by Capacitorial
      Hello guys,

      I have a Philips 240B7QPJEB. The monitor seems completely dead.
      I opened it and measured the voltages of the powersupply. I found that a mosfet was dead and replaced it.
      On the connector, that goes to the TCON board, all voltages 15-19V and 5V are present.
      The small connector on the left of the PSU has two cables with 18V and all the other have 0.2V. It connects on this small connector on the left ontop of the panel. I guess the backlight? Seens fine I guess.
      The weird thing is, that the Power LED is powered over the TCON board.
      On The TCON...

      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....

      Anker SoundCore 2 Bluetooth Speaker Turns Off After a Few Seconds (Possibly Firmware Issue?)
      by zklgfs
      Hi,

      I have an Anker SoundCore 2 (A3105) that I saved from the trash (well, I guess there's a reason why it was supposed to go into the trash...). The problem is that it always turns off after a few seconds (sometimes it stays on a bit longer, between 30 and 60 seconds, but it still turns off). The power light turns on and the bluetooth light starts blinking, but both abruptly turn off again. The "turn off sound" is still played after the lights turn off. Sometimes, it also loops the on-off cycle several times without me pressing any buttons. If I connect an AUX cable, music...
