    Sony KDL-40Z4100 3/4 of the panel is distorted and full of lines

    Sony KDL-40Z4100

    My buddy had this tv mounted on his wall. He told me it was ghosting and I thought it may be a t-con as15 chip.

    Then I got it home, turned it on with my Hisense Sero 7 pro tablet connected via mini hdmi and then I saw this mess. It turns on and lights up but about 3/4 of the screen is just lines and smeared. The top portion seems to work but very very slowly. It seems to bleed downward and the image is hazy and ghosts during movement. It looks like the tv is having an acid trip.

    When I press the input button on the side of the panel the TV is very slow to respond and require multiple button pushes. Volume and power work fine. The audio is clear and loud. I tried mulitple HDMI ports to try to see if one of them is bad but it is difficult to ascertain which input you are on since the letters seem to bleed into each other but on all the inputs it's the same.

    I was initially thinking it was the t-con but I kind of wonder if this is just a bad panel?

          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 KD-55XG9505 lines on screen problem
          by Chrissygizmo
          Hello again everyone,

          This is my latest mission, to try getting this Sony tv back to normal working order…

          I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried...

          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...

          Sony Panel Swap Experiment 65x900h with the panel from a 65x930d
          by r3vsEngIT
          65x900h with the panel from a 65x930d.

          900H: model yr 2020, Samsung panel
          930D: model yr 2016, Innolux panel

          spec wise the panels are the same. the drivers and tcons are obviously different but what made me want to give this a try is that the wiring diagrams for the data signals going into the tcon for each tv were nearly identical. there are only a couple pins that i am unsure about and that is what brings me here.

          the 930d has the DPS board where the 900h has none, however, if you follow the pins to the BM1 it would appear that the signals...

          Sony KDL55W800C Lines Across panel
          by Hwciua4i
          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!
