    Samsung TV with black screen

    Hello, good morning, I have a Samsung TV,
    Model: UE32F5700AW, when I turn it on
    it has sound and the led of the panel light up but the image
    is absent, I have been told that it may be the
    T-con. In the input and output of the fuse of this card I have
    12 v., But I do not know where to measure more tensions in the T-con.
    The code of the T-con is RUNTK 5351TP 0055FV ZZ.
    Please can someone tell me the steps to follow for
    find the problem
    Greetings and thank you.
    P.S. Sorry for my English.

    Please upload good clear straight shot pictures of the whole T-CON board and also the whole back side of the TV showing all the boards.

        Looks like F100 was bridged and was open circuited again. If you do have 12V on both sides of F100 then measure the voltages on VGL, VGH, HVDD and VCOM and report your findings.

          Hello, indeed the fuse is bypassed because it was fused and as I said in my first post
          I have 12.4 v. At the entrance and exit and in the points you mention I have no tension.
          A greeting.

              If the Flat ribbon cable to the Panel Bd. is disconnected, do these voltages come up? If yes then the Panel is defective, if no then a new T-CON Bd. should solve your problem.

                Mainboard there, need to check white sticker numbers to see if its a match, 60 euros for a 32 inch tv seems a bit high tho. https://www.ebay.es/itm/PLACA-PRINCI...13WS:rk:3:pf:0 Oops, thought you were looking for a mainboard.

                  Disconnecting the flat cable that goes to the
                  Main-boar, the voltages remain the same, absent.
                  I understand that it is necessary to change the T-con, I can replace it
                  for a Runtk 5246TP instead of the Runtk 5351TP.

                    I read on the network that the Runtk 5246TP card gives less
                    problems that the Runtk 5351TP.

                      Yes a new T-CON will fix your problem.

                        Thanks, I'm going to order the T-con, runtk 5264TP and when the
                        receive information about the results.

                            What we need are the Voltages of VGH, VGL, etc. on the T-CON board test point when the ribbon able between the T-CON and the LCD panel are not connected and connected, not the cables to the Main board. There are many Voltage test points on the T-CON board that need to checked and reported.

                                What we need is the OP (gua45) to provide the Voltages from HIS T-CON board suggested in my post #14.

                                          Hello,

                                          YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

                                          I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

                                          On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

                                          I also changed the screen because the PC fell and the screen was broken.

                                          I changed the battery with a new and original battery.

                                          I also had corrosion/oxidation on the...

                                          Hello,
                                          I have my TV model UE50KU6070 which I am trying to repair.
                                          BN41-02528A / BN94-10800C motherboard.
                                          If I disconnect the motherboard from the power board, the backlight works. When the motherboard is connected the backlight works but the screen remains black.
                                          When I plug the TV into the electrical outlet, the standby LED lights up but no reaction to an attempt to start it with the remote control for about 1 minute. During this minute the TV consumes about 20W.
                                          After one minute the consumption drops to 0W and the TV can turn on with the remote control but...

                                          Hello everyone !

                                          My name is Chris, I am a 30 years old embedded software developer working in the automotive industry. I am really passionate about learning new skills and repairing/crafting stuff. I came around this forum last week with the goal of repairing my faulty gaming laptop, indeed, I was video editing on it when suddenly a black screen popped and never disappeared I bought some stuff to try to repair it and learn as many things as possible about computer repairs but nothing worked so far. When the black screen appeared, my legion 5 pro was connected to my external monitor...

                                          LG 82UN8570AUD ~ TCON or PANEL?
                                          by kca
                                          Hello all ~

                                          Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.

                                          When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.

                                          I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped...

                                          Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
                                          I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...
