    Toshiba 22AV500U horizontal lines on screen

    Horizontal lines 1/4 way down from top. When set is unplugged then plugged back in and powered on the screen below those lines freezes. With a gentle thump to top of set the picture comes back but lines are still present. Set ain't worth nothing but good for practice. Suspect t-con but on this set it looks as if its integrated to pannel. Ribbons to screen don't have a standard connector. Is this true?? The pics are bad but you can get the idea

      Almost certainly the panel, t-con wouldn't cause this even if removable.

              Hitachi 58HK6100U - Horizontal Lines (Bottom third of the screen)
              by kdaniel
              As stated by the person I collected the TV from, it just stopped working overnight. However, I still gave it a go to try and repair it.

              There is a thread on the same TV but with slightly different issues where they had to tape connection points on the ribbon cable, so I want to see if this is repairable by any chance.

              After bringing it home and plugging it in, the TV turned on with its backlight working but had no picture. After removing the back cover, the first thing I tried is to unplug one of the ribbon cables and the situation is as follows.

              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...

              I have seen many youtube videos with guys who put a tape in ribbon cable and TV fixed in a magic way (I have tried without success).

              My TV model is: LE46C750R2W

              Samsung QE50Q60TAU - Horizontal screen lines
              by Runlinc
              Hi everyone, the tv was in a continuous reboot cycle. To get the best screen image i can I taped the VGH and VSS pins on the left side buffer board joining ribbon.

              I am left with a good image apart from the black horizontal lines that I cannot get rid of.

              I cannot find anything on the buffer boards that has shorted.

              Do you think there is anything i can do to eliminate the lines, or are they caused by an internal panel short and the image cannot be impoved.

              Many thanks for your assistance
