    Sony KDL55W800C Lines Across panel

    Hi,

    I have a Sony KDL55W800C which suddenly started showing horizontal lines moving up and down the screen. Initially, it would return to normal after a while but then it stayed for a few days.

    I have now replaced the mainboard and the T-Con panel on the unit and the issue persists.

    Any help on troubleshooting and getting the TV back to regular working condition would be greatly appreciated.

    Thank you!

    Horizontal lines are bad panels. However, if you have a tcon board, you may be able to repair it with the tape cutoff method.

      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

      Sony KDL-50W685A horizontal black lines Pattern
      by Raulnn
      good morning! I have a problem with this Sony. The image has a pattern of black horizontal lines, I attach a photo of the lines. The power supply is external and emits a sound. I don't think it's because of that. Let's see if someone can help me.

      Sony XBR65X900H TV with Horizontal Lines right half of screen
      by dvu0627
      I have a Sony Smart TV XBR65X900H that started to have horizontal lines on the right side of the screen (see attached picture). When I played video on Youtube green horizontal line at regular intervals(1/4") across the screen.
      I replaced the T-Con board but the lines are still there.
      I believe this issue is from the Main Board. Before I replace the Main board, I wanted to seek advise if this is the problem from the Main board or something else?
      Thank you for the help....

      Sony KD-75XF9005 grey Picture but Sound. TCON or panel?
      by iglitare
      Hi,

      i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
      Backlight seems to work, Sound (Setup menu after reset) works.
      If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
      Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
      With my small knowledge i would think at least the cables are good.

      Can this happen because of a bad tcon board?
      Or is it always a bad/shorted...

      Samsung UE70TU7020K Which lines to tape on a bad panel
      by learnmore
      Hello Community,

      I'm working on a Samsung UE70TU7020K.

      It looks like a bad panel. There is only 1 FPC cable from the Tcon (built into mainboard) to the panel.

      I'm using a piece of tap a few mils (covers about 8-10 pins), at different locations and have had varying results but nothing that is remotely watchable (multiple lines across all the screen, half screen and total black out on screen). The buffer board is divided into 3 boards. I've disconnected the end board one at a time but each time the screen was totally black. I presume it's because the potential...
