    I think t-con problems cause vertical problems not horizontal
    I assume no responsibility for any stupid suggestions I might post.

      Those are horizontal lines.

        Ok, spoke to service guy, it is panel problem - he said he will tear panel apart and try to repair it, there's a small change he'll succeed.

        Thanks for answers

          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...

          Sony XBR-65X750D Horizontal lines bottom of screen
          by ggil44
          Hi, I have a Sony XBR-65X750D that has horizontal lines at the bottom 6 inches of the screen. These lines appear to be every other line because the picture is still quite visible behind those lines. The lines appear all the time with a few other lines above and below the 6 inch level blinking on and off at about 2 second intervals. I'm not sure if this is a panel issue or power supply/main board problem. I did replace the T-Con board without any change in the problem. Any suggestions you might have would be greatly appreciated. Thanks,

          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...

          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....

          Samsung QN50Q60t lines on screen
          by jeyoung12
          Hi all
          I have lines on the screen...which is an age old problem that can be remedied by watching Youtube videos and getting out the tape.
          My issue (after successfully fixing a different sammy tv with a separate tcon board and isolating the side of the panel...):

          This tv has an integrated tcon...so it is a bit more confusing when trying to isolate the clocks.
          It has a c ribbon and i have taken each end out to see if that will isolate the lines. instead, it makes it much worse ALL over the tv!

          So....i don't know what end of the C ribbon to work with...
