    Samasung Plasma - PN50B550T2FXZA Horizontal Black Lines Forming

    Hi,
    I started getting these (1 pixle thick, I think) lines appearing on the screen of my plasma TV. It started with one and they have been multiplying since the first one appeared. I've gone online an searched for fixes. I've already switched out the following boards and the problem still remains:

    Y-Main board (LJ92-01611A)
    Y-Buffer board (BN96-09745A)

    Any ideas what the try next? Should I replace the main board (BN96-12139A)?
    We had a power surge a while back and these lines started occurring shortly after. Also I've noticed on the main board not all the HDMI ports work correctly anymore. Any suggestions would be greatly appreciated. Thanks in advance.

      550's are known for this failure. either you got a bad Ybuffer or your panel has failed.

      Mainboard will not fix this unfortunately.

          Well I already replaced the Y Buffer and that did not resolve the problem. Is there another name for the panel? Is this a part I can buy online?

              Nope. The panel is the screen itself and attempting to replace that will set you back more than if you strolled into a store and bought a whole new tv.

              Unfortunate but that is where you're at.

                  Well I guess it's time for a new TV. I thought I could salvage it but that's just not cost effective. Thanks

                      TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board

                      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

                      by xNOTx
                      Hello 👋 I have a tv with these red lines. I've tried cleaning and re-seating the ribbon cables but no luck! Tried all 4 on the LJ92-01485 board and on the bottom of the panel. Do you guys think it's the board?|

                      Samsung Plasma TV with vertical lines (model PN50B430P2D)
                      by afex
                      This is my 2nd broken TV I'm trying to fix and haven't been able to figure out... currently going without any working TVs so am hoping to be able to fix one..

                      This Samsung PN50B430P2D Plasma has this big block of vertical lines which will fade in shortly after turning the TV on. The lines will sometimes flicker a bit or fade in/out and sometimes it just stays present. The length of time it takes them to appear varies, sometimes its a few minutes and other times it appears immediately after powering on.

                      I have attached an image of the TV with these bars displaying....

                      Friend of mine has a Samsung Plasma panel with some vertical lines that are starting to form on the screen.....Ive never worked on a plasma panel, so Im not sure what to look for, would this typically be a main board issue, or something else?

                      Any help would be appreciated.....Please let me know.......

                      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...
