      Reseat the cables on the Y-buffer side. (If you need help locating the Y-buffer take some photos inside the chassis.)
      If that doesn't fix it, then the panel is bad. Not economically repaired unfortunately. These 2010 Samsungs seem to have a lot of issues with the panels going bad.

          Man that looks like a bad case of samsung panel failure. Did thus happen all the sudden or are more lines dropping out slowly? I have ran into this and re placed buffers, resoldered ribbon connections, tested and tested last year on one of these.
          Like Tom66 said. At least try to reseat the ribbon connections.
          Did I leave the soldering iron on?

              I agree that it doesn't look promising.

                  Samsung plasma 50" TV, model PN50C540G3F, has black horizontal lines
                  by CyberNinja
                  First, the black horizontal lines even overlay the TV's menu. Does this behavior indicate that it's the plasma panel that's defective? If not for the black lines, the TV works just fine. I've cleaned the 6 connectors between the panel and the Y-buffer board, causing no change in the black lines. Visually, the 12 ICs on the Y-buffer look brand new (no holes, etc.). I put my fluke meter in continuity mode and tried to perform the "short" test on the 6 panel ports and found many shorts. But I don't think I'm doing the "short" test correctly and I'm hoping someone can provide guidance....

                  Samsung QN70Q6DTA Ghost or horizontal lines after tape fix horizontal line
                  by Ihandyrepair
                  Hi guys

                  I just started fixing 4k TV few months ago. so I am still learning a lot
                  I got this tv from friend complaint is ghosting or horizontal lines on image.

                  never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
                  then it started to show the ghosting white image.
                  I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
                  it has 3 thin small boards at the bottom of the...

                  Samsung UN46C8000XFXZA vertical bars/horizontal lines
                  by x_orange90_x
                  I posted about this previously but didn't get any response, and I have some troubleshooted a bit so I have more info.

                  The screen is full of horizontal "gaps" or lines that distort the picture badly, and after about 10 seconds of powering it on the screen starts to fill with red vertical bars that take on the horizontal pattern. After the screen filled with the red bars, they instantly vanished and then slowly started to reappear. I initially thought it was tab bonding failure, but after getting down to them and pressing each one I find zero change in the picture. I went...
