    LG 60PA6500 no picture

    Hello;

    I have an LG 60PA6500 with no picture but it does have sound. I have read many posts here that helped me with some troubleshooting but now I am stuck.

    The voltages going to the Y-sus and Z-sus boards match what they should be.

    I had read that if you remove the top Y buffer and get a picture on the bottom half then the panel may be shot so I tried that.
    When I remove the top Y buffer I get colored lines on the bottom half of the screen.
    When I remove the bottom Y buffer I get colored lines on the top half of the screen. If I get lines there then the panel is not shot, is that right?
    If both buffer boards are in I get no video at all but there is sound if I am connected to my aerial.

    I have replaced the Y sus and Z sus boards. I also replaced the main board as it has had a bad HDMI port since shortly after our house was hit by lightning about a year ago.

    Any suggestions? I would really appreciate the help!

      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 UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
      by JJAAMM
      This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

      Problem
      TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

      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...

      TCL 49S405 double image
      by howardc64
      LCD displays a 2nd image slighty offset vertically. And multiple pairs of black lines along the bottom. Probably common as google "TCL 49S405 double image" pulls up this ifixit post ( link ) with identical ( nearly, but their fault seems to be on the other half of the panel than mine ) problem without solution.

      This one looks to be a more difficult to diagnose because most? of TCON seems integrated ( CSOT BGA on buffer baord) into the left panel edge board ( looking from rear of TV) There are 2 buffer boards for each 1/2 of the screen. Main connects to the left buffer board...

      LG 82UN8570AUD ~ TCON or PANEL?
      by kca
      Hello all ~

      Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.

      When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.

      I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped...
