    Samsung UN65TU8000 - Panel Issue [ hole in ribbon cable ]

    Well, I will be the first to admit that I screwed up...

    In attempting to replace the backlight in a UN65TU8000, I made a hole through one of the ribbon cables between the board that runs along the bottom of the back of the TV and the panel. This lead to a between a 1/4 to 1/2 inch vertical stripe running the full height of the image.

    I don't have the experience; personally, to solder a bridging wire for the paths that were cut. So, I have been on the hunt for other Samsung TV's of similar size.

    I have 2 that I have found and have in my possession.

    UN65RU730D - Bad Backlight / Good panel [ I've already attempted to replace the backlight and the replacement does not work on part of the TV ].

    UN65NU6900 - Non-working / Apparent bad main board

    I do have another 65" that has a panel that is shot [ spider web cracked / full black / no pic ] but cannot remember the model number.

    So, those here with more repair experience, can I use the one of the known or assumed good panels on the other TV's on the TU8000?

    They appear to be the same or very similar to each other. I have not been able to locate the service manual for the RU730D anywhere. I did find the service manuals for the TU8000 and NU6900. The manuals list the panel types as 65B6AU0GT and 65A6AUANN respectively.

    I dont want to toss good parts or screw up a good panel due to some incompatability that I dont know of. And I especially dont want to fork out for a replacement panel.

    If I can't swap the panels, then could the ribbon cable be salvaged on the original panel?

    I patiently await the wisdom of those who know better than I.

    Sorry about the bad edit job on the photo.

    List the panel numbers of each tv, label/sticker should be on the back chassis someplace, also list the full model version FA01, Fa02 etc, should be on the back cover.

      Don't any of the other ribbon cables match, count the pins.

        UN65RU730D mainboard might work in UN65NU6900, look both mainboards over very closely see how they match up and check those model versions on the back covers.

          I'm not talking about the mainboard; but the LCD panels on these.

          I have pics of the model stickers but not of the sticker on the metal chassis of the TV's.

                  I see, I thought you were trying to make one tv work from the various parts.

                    That is exactly what I am asking... Can the LCD.panel from one of these with a good LCD but other issues replace the one that has a broken LCD but otherwise working?

                      putting the numbers here for easy reference .. as i see the differences between these need to be found to see if somehow compatible . 65B6AU0GT and 65A6AUANN
                      are these the complete panel numbers ?

                        From the service manuals that I have been able to find. I have to reopen the backs of a couple of them to get the info off of the sticker on the chassis.

                        I did confirm matching info on the TU8000 of 65B6AUOGT from the chassis sticker.
