    Samsung UE55AU8072U no standby light

    Hello,
    i have here Samsung UE55AU8072U no standby light.
    Panel model : CY-SA055HGXY1V
    Motheboard model : bn41-02844A bn94-16868V
    When i press the power button,standby light turn on,after i release it immediately turns off.
    Unplugged main board from power supply - BACKLIGHTS COME ON.
    I think the motheboard is problem.
    I fixed two TV with same mistake,but they were 6000-series,there was a problem with the contents of the w25q40 chip.
    Here are all dumps : ic801(24c512),ic1603 and ic1604(25q40).

      Try disconnecting the screen FRC's from Main board, This will rule out a screen fault, look closely at the stand-by light when mains voltage applied, if it flashes twice then it is a screen fault.
      Hope this helps.

          Thank you for answer.
          The same thing happens, the standby light only lights up when I press the power button.

                  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...

                  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...

                  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...

                  Samsung UE60KS7000 No Standby Light
                  by marcinq
                  Hello,

                  I've got a problem with a Samsung UE60KS7000 that was given to me and said that there was a problem with the One Connect box but as I understand the TV should turn on even with the One Connect box disconnected (which it doesn't). There is no stand by light.

                  I've disconnected the Main Board from the PSU and when connecting to mains the backlight turns on which suggests the PSU might be ok. I've measured the voltages out of the PSU and they seem reasonable (like the labels say). The main board has no obvious burns, there are no shorts on the power rails anywhere....
