    LG C1 65'' dead standby

    I've owned this C1 from new since late 2021, and it has now suddenly started with the following symptom:
    If power has been connected for a while, the red standby lamp turns off, and the tv wont turn on (no reaction from remote or button on tv).
    If power has been disconnected for 5 minutes, the tv turns on fine, until turned off and left for a couple minutes, as the standby light will then turn off again.

    I've seached and found that this is most likely a failing PSU, and I've seen repair services on eBay fixing these symptoms, so I am hoping that someone here has fixed this before.

    I haven't found a diagram for this yet.
    PSU: EAY65689423

    check the power board if it has a microcontroller, it is maybe damaged or planned obsol. inside..

          Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
          by tvguy12012012120
          This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

          Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

          Greetings to all, a while ago my TV was dead, it didn't turn on and the standby light was off, the next day it is working. But these days it no longer wants to turn on, I did some troubleshooting, I disconnected the main board, I checked the voltage on the backlight and there is 400 DC, when I connect it again the main board the voltage drops, in all that troubleshooting, miraculously the standby light comes on and the TV works. After an hour I check and test, I turn on the TV, the Stanby light flashes 3 times and it...

          Vizio D50u-D1 Dead Set No Standby
          by fharris1977
          Hi. I got a Vizio with no power or standby, and won't turn on with remote or button. I checked the voltages on the connector and all read 0.00V or nearly 0(0.050 ON/OFF pin). None of the pins are labeled STB for standby although I do see some 5V pins. Other than the obvious standby led, which isn't coming on, is there a way to check for standby voltage on this PS. I'm trying to see if my problem is the PS or mainboard. Some Vizios I have fixed with no standby led me to think it was the PS but it turned out being the mainboard. Any experience with this set would be greatly appreciated.

          MacBook Pro 2011 turns on with keyboard light , screen dead
          by Rav_tangle
          Hi all , thanks for having me & I think this has been asked before but my case seems a bit odd.
          I have a MacBook Pro , board 820-2915a and it turns on , chimes etc etc , keyboard lights up, fans spins , can turn caps lock on/off but screen is dead.
          Iv tried the resets , shine torch through back logo , nothing , it seems the screen has no power. If I plug charger , it charges but if I disconnect battery it displays green light but won't turn on. Iv tried screen on with another board & it works & seems I'm not getting any voltage at pin 2 , next to ground pin .
          is this...
