    Can you explain how you can hear the relay wanting to click?

        You will need to post clearer photos for us to work on.
        Have you checked the PSON and 5V standby voltages? Do you have a DMM?

          LG OLED77B29LA shuts itself down/doesn't start
          by ILoveZeroTwo
          Hello,

          I'm trying to fix a TV that got damaged by rain (open window during a storm).

          The TV at first would start up and work completely normal, with no lines on the screen or anything. But after about 30 seconds, it turned itself off. After it shut itself down, starting it up directly afterward is no longer possible.

          The standby light is red and it blinks once on the power-on command by the remote. The relay also does not click anymore when plugged into the wall.

          Standby voltages are all present and stable, approximately 13V for the 20V line...

          Sony TV model KD-65XE7005 - only Sony logo for 3 seconds
          by mauda
          I'm currently working on repairing a malfunctioning Sony TV model KD-65XE7005 with the mainboard 1-981-926-21. I would appreciate your assistance with this issue.

          Upon powering on the TV, the Sony logo appears for approximately 3 seconds, after which the backlight remains lit, the screen remains black, and nothing else happens. The TV consumes around 55W initially and then drops to 35W. The indicator LED remains solid white. It doesn't respond to the remote control. When attempting to update the TV using a USB dongle, the dongle briefly flashes but nothing else happens.

          Vestel 17MB82S EEprom dump required
          by Davy no Caps
          Hi all,
          First time trying to fix a TV for a friend, it's a Bush DLED32165HD.
          Power Board - 17IPS11
          Mainboard - 17MBS82S
          Panel - VES315WNDB-02

          Red blinking standby light is on steady, press power button on remote and light flashes 7 times then stays steady, press power on remote again light flashes 10 times and then goes off.
          Checked all the voltages on the power board inc backlight circuit, they all read ok and are stable. Backlights tested with backlight tester and all work fine (2 strips x11LED on each).
          No picture, backlight or sound just blinking...

          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...

          Samsung UE46F6400AWXXC not powering on, standby LED off
          by UltimateNeutrino
          Hello, since yesterday our Samsung UE46F6400AWXXC no longer powers on, with the standby LED off. It turned off when someone attempted to clean it, not sure if related. A few days ago, there was a similar issue, but it was solved after unplugging and replugging the power. Additionally, another user of this TV reported issues of the screen turning off randomly, which were solved changing the channel.

          I originally suspected the PSU, but if the mainboard is unplugged the PSU relay closes and the backlight turns on. It's only when the mainboard is connected that the relay doesn't close...
