    Sony TV, KDL-55EX621, white/grey screen with lines

    I have this 55" Sony LCD with a video problem. The sound seems ok and the screen lights up but there is no picture data. The screen has large blocks of gray & white with darker horizontal bands scrolling upwards. See the photo below. If anyone has any suggestions, please let me know what other info is needed. Thank you in advance.

    looks like panel failure.

    Bright band looks like maybe liquid damage on the tab, from cleaning maybe

      Panel failure likely not fixable

        Would this mean that the boards are still likely to be good?

              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,

              Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed🙏
              by Daren87
              Hello everyone,

              I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

              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...
