    Samsung PN50C6400

    I have a Samsung PN50C6400 which has at least two line issues (picture attached). There are horizontal black lines of different size (perhaps wider ones are just multiple lines appearing as one) banded across middle of screen (none on top or bottom 20%). These lines started some years back and have slowly increased in number/size. They can be annoying, but i guess i have gotten used to them and often don't even recognize them when watching, but would like to "fix" them if possible.

    There are also some vertical, colored lines right of center and near right side. They have appeared after the vertical lines and have not grown to the same extent as the vertical lines.

    What are the thoughts about this?

      Junk it. The vertical lines are the kiss of death for the plasma screen itself. Not repairable, sorry.

          Timmy,

          Thanks, I was suspecting this given what I had read on some other posts. Do you think the horizontal black lines are the plasma screen as well or the Y board(s)?

              It could be the buffer boards, but I suspect the screen.

                  Is there a way to test the boards other than replacing?

                  If it is the panel then the boards should be good to sell, but if it is one of the boards then it would be too risky to sell boards.

                      There are YouTube videos for that.

                          Screen Display Vertical Multicolor Lines
                          by Stanley1843
                          Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...

                          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...

                          Thin stable coloured vertical lines on Samsung UN65NU6900FXZC come and go
                          by polaro
                          Greetings,

                          I've bought a used Samsung UN65NU6900FXZC LED TV. It worked fine for some time and then developed, at first, a single very thin (1 pixel) vertical stable blue line, from top to bottom, close to the left edge of the screen. Now it's 3 lines on the left. When I connect HDMI sources the number of the thin lines grow. After disconnecting and cold discharging I am back to 2 lines. The lines disappear at a rate of 15-20 minutes per line. So it does not look like a damaged LED panel. Any advice? Thanks...

                          Samsung 55" UN55JS9000 - Pink vertical lines due to chipped LCD panel?
                          by Anonmis
                          Hello all, I was recently repairing my Samsung 55" UN55JS9000 tv from the common burnt backlight LED's and cracked light guide panel issue. After replacing the LED's and putting the TV back together, I tested the tv and all I was getting was sound but no image. Somewhere along the way (could be related to the next issue) the T-Con board became damaged and after replacing it I have made a little bit of progress but now have bright pink vertical lines and still no image.

                          The bigger issue .... I took the TV apart again and realized that I likely didn't sit the LCD panel correctly...
