    Samsung UN55D7000LF Display issue

    Hi,
    Having an issue with the display. Is this a ribbon issue? Is the same in all inputs and menu.

    It's a bad panel.
    you'd need to take it down to the panel, press on the ribbons to see if the picture comes back.

        yep... that's is likely the ribbon that generates that side. Must be some story behind this one as I don't think it would have just disappeared... :-)

          History of this TV? Someone/shop else worked on this unit before?
          That black vertical line is due to bad panel.

            Most likely, if you put that ribbon cable back, it won't turn on at all.
            Do you see some damages at the T-Con board, panel's PCB/tabs?

              The history is I bought it from a guy who had a bunch of tvs that was moving. He told me the ribbon was the problem, I wanted to confirm before I bought it, which seems it may not be.

              The tcon board looks in good shape.

                  have you tried swopping the ribbon cable to the other side? if so what image do you get then.

                        Check for shoddy connections on some of the resistors and capacitors up on top of that FRP board that connect the ribbon cable to the panel on that side. I've seen a few instances where there is a bad connection or a bad solder joint on some of those SMD capacitors up on top of that board. If not your panels definitely bad
                        Did I leave the soldering iron on?

                          bad panel i guess then but atleast you can either keep or sell the boards and led strips out of it to get some money back etc

                            are these panels not repairable? Ive been told you can get the bonded tabs replaced?
