    Samsung PN51F5300AF does not turn on

    We had a lightning strike very near the house and my 51" Samsung turned off. No other devices even blinked. Lights never flickered and cable modem stayed on.
    No Standby light, nothing. This was the only device in the house affected.
    Fuse tested good.
    I replaced the Power Supply board thinking that was it, but no change. No standby light, nothing.
    Then I replaced Main board. Now the standby light comes on, it goes off when TV is turned on but nothing else happens.
    The green LED on main will blink a few times then it goes off.
    Turned the TV off with switch and the standby light does not come back on.
    I have to unplug from power. When plugged back in the standby light comes on again.
    Replaced X-Y Board, and Buffer (see photos) No change.
    So every board except the X and Y Sustain boards have been replaced.
    Standby light until turned on, green LED blinks and then off, no sound nothing. Standby will not come on until unplugged and plugged back in.
    Zero volts on VS and VA test points.
    So I figure one of the replacement boards I got is no good (guaranteed used) But which one??

          Well....No responses here so I contacted the folks I got the boards from.

          Consensus was they had sent me a bad main board.

          They dropped another one in the mail to me, 2 day shipping, at no charge.

          I'll put all the other original boards back in and start with the new (guaranteed used) main.
          Hopefully I can send all the others back for a partial refund.

          I just want to fix my plasma screen TV, since you can't buy them anymore.

              OK... The main board was the problem all along, and the first replacement I got was also bad, leading to much consternation.

              Installed a good main and all my original other boards and life is good.

              Lesson learned, lighting strikes nearby will take out the main, and that's the first place to look.

              Interestingly, once the TV was fixed I found the HDMI output from the cable box was also affected by the lightning strike. The composite video output worked, but had to get a replacement cable box to go back to HDMI cable connection.

              OK. well, no help from here, but I sorted it anyway.
              Cheers

                  Good job. Luckily you were able to find replacements for all the boards and even get a working Main Bd from the Seller. Good JOB.

                      tvpartstoday.com took care of me.
                      Guarantee on the bad board and let me return all the others at no charge !!
                      They gave me really great service, so I will recommend them to anyone looking for tv parts.

                          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....
