    KDL52w4100 Broken - No power or standby light

    I have a KDL52w4100 with no blinking lights or any signs of life, however i have 3V at the connector going to the logic board but no power on any of the other wires at this connector. (e.g. 12v UNREG, 12VREG...etc) thoughts? Logic board? Power supply?

    I tried a replacement power supply but i dont even get 3V on the standby wire connector going to the logic board. Maybe the replacement power supply is broken.

    Replaced the main board using my orignal power supply, power came on, then showed 14 red blinks. I unplugged the TV now it just shows green light for a second then nothing again. Maybe the main board is not the correct version, it looks slightly diff and has diff numbers?

    Thanks

    Last pic is the main board i recieved (it does NOT have a tin cover around the HDMI)

    If the Main Bd. you tried looks different and have different numbers then it will not work. So you are getting the 3.3V StandBy on the PSU, correct?

      Yes I have 3.3
      It does look slightly diff. I am confused about the numbers. The board and part numbers are the same but the little white sticker has some diff. Numbers. The seller indicated my serial number range but the most apparent diff is my hdmi ports have a ton cover and a lot of the ones I found including this one do not.

      The tv did show some life but not fixed. Now it's kust green light when I plug it in and then nothing. The other main board nothing all together. At first the screen did turn on but all weird and then it went off with 14 blinks over and over. As soon as I unplugged it never blinked again

        LED TV Samsung The Frame 55 inch QE55LS03RAU Standby Light only
        by ChristianBr01
        Hello everyone,
        I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
        The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
        What I already found is that the 12.8V are not an the connector to the main board connector to the power...

        LG 55EG910V - no power and no standby light
        by AleMonti
        Hi everyone,
        I'm trying to troubleshoot and repair this old LG OLED curved TV, model 55EG910V.
        I did some basic troubleshooting and reviewed most related posts here, but I wasn't able to isolate the issue.

        The TV shut itself off during playback and never came back to life - the standby light remains off. My dad claims that it has happened a few times in the past but the issue resolved itself after some time. Not this one.

        After checking the basics I did the following:
        • I measured all voltages and as expected the only active supply is the 3.5V standby. It

        Samsung QLED QE65Q7FNAT only standby light
        by Kaar3l
        TV: Samsung QLED QE65Q7FNAT
        PSU: BN4400940A
        MB: BN94-12832K

        I got the tv in spring 2024. At that time it started, then ran 60 sec and poweroff. Seemed like reboot issue. I didn't have time and room to check it in summer so I plugged it in and now the standby light is on. I press button on remote, standby light goes off and tries to start?. No picture or backlight on LCD. I thought about removing diodes like in this thread: https://www.badcaps.net/forum/troubl...sung-qled-q60r...

        Philips 37HFL5682L/F7 no standby light, incomplete service manual?
        by jasonbay13
        picked up a tv and when the power is plugged, the standby light flashes real quick then goes off. of 3.3, 12, 24v is all there but i couldnt find any 5v on the back-end board. ON/OFF is low, which it seems is what turns on the backlight so i removed the wire at the back-end board and put a 10k resistor to the 3.3v, which when plugged in brings on the backlight for a split second and also a blue light "LED1" on the inverter board, which goes off after a short time.
        am i missing something to bring on the backlight or is the inverter/ccfl gone bad? would that cause the inverter board...

        Samsung UN70NU6070F Standby Light flashes twice
        by Nicktronic
        Hey Everyone,

        So I've got this Samsung and the reported issue is that when powered on the backlight comes on, but no picture, no sound, it will flicker, the standby light will flash red twice and repeat the whole process...each loop lasts about 15 seconds.

        I've googled the issue and understand it is likely a panel/driver board issue, but was hoping the "tape method" could be successful. Before I did that though, I disconnected the left LVDS cable and powered the TV on. This time I got sound, no picture and the two blink standby light stopped. Did the same...
