    SAMSUNG UN46D6420UFXZA bad t-con

    i have narrowed down the problem to a bad tcon though i dont see any physical damage on the board it self(not sure if its really fried or not). what id like to know is where can i buy a replacement board? it has to be in the lower 48 states and it cant exceed $65 with shipping.
    this is the exact part i need

        That is expensive T-CON, you need to match the P/N as printed on the barcode sticker.

          How do you know, that is the T-con the problem?
          I'm just trying to warn you about these TVs, they suffer from bad panels.

              Hello,
              You will need to run the tv with one ribbon cable connected to the panel at a time( make sure to do both sides). If you get a good half picture it is likely a bad panel.

                The SMD fuse is on the T-CON board, it will be closed to the LVDS cable, please up load the pictures of the T-CON we can show you where the fuse is.

                    The fuse is the white rectangle with the gold ends above the bottom conector. You should read the same voltage to chassis ground at both ends, If there isn't any voltage it's either a bad mainbord or the cable.

                      The right side works but the left side is black, so is it the screen or the t-con board?

                          I had the same exact symptom on mine, shorted panel.
                          That is why I ask, to don't waset money on this TV.
                          D series has bad panel, that is a known fact.
                          I could pick up a 55D6050 which is (completely)dead, but I'm scared.
                          Bud, what do you think, I should go for it?

                                Hello guys.
                                I'm having the same problem. I try to remove one of the two ribbon cable between the tcnon and the panel. With a right cable removed the tv doesn't power on, but with the left cable remove I Can see a part of picture as in the pic. I still don't know if the problem is the tcon or the panel...

                                  For the heck of it check for shorted capacitors across the top panel boards
                                  Did I leave the soldering iron on?
