    PN51N450A2D horizontal lines

    The tv has a great picture. However, the bottom 8-10 inches of the screen has black horizontal lines. Have replaced the ysus and xsus.
    Any suggestions ?

      I'm afraid that panel is toast. This is an inherent samsung issue with the newer samsung plasma TV panels. Have seen it quite a bit lately.

      There is as far as I know no fix for this. Has something to do with the electrodes in the panel coming detached from the ribbons. You can try unplugging and reseating the lower ribbon cables but not sure if it will help here.
      I'm sorry
      Did I leave the soldering iron on?

                      TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                      by howardc64
                      All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                      • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                      • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                      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...

                      Sony XBR-85X950G Gray horizontal lines and vertical picture shift diagnosis?
                      by noisykid
                      5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...

                      Samsung UN46C8000XFXZA Horizontal lines
                      by x_orange90_x
                      I just acquired this 3D LED yesterday and it has horizontal lines on a little more than half of the screen. When I first turn it on it has thin black lines going across that makes the image look serrated, and then shortly after patterns of thicker red lines fade in. If I turn it off and right back on it will reset to just the black lines and the red will again fade onto the screen.

                      I initially thought tab bonds, but flexing the bezel makes no difference, and the fact the image sort of resets after cycling power is different. I haven't opened it up yet to actually test applying...
