    Sony KDL-40W4500 panel problem?

    Sony KDL-40W4500 with a picture problem. (see attached pictures)

    Left part of picture having the lines "mirrored" from top to bottom, while the right part is next to problemfree, except for some brighter lines.
    The normal question:
    Is this a panelfailure? Or a T-con, mainboard failure?

          So, a panel failure then? Not possible to repair?

          BTW, it can be good after 15 minutes of operation.

              Not impossible to fix, but the repair isn't always long lasting.

                  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...

                  Lenovo T580 - LCD Panel problem - error 0288
                  by perzyk23
                  Good morning,
                  I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise....

                  Sony KD-75XF9005 grey Picture but Sound. TCON or panel?
                  by iglitare
                  Hi,

                  i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
                  Backlight seems to work, Sound (Setup menu after reset) works.
                  If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
                  Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
                  With my small knowledge i would think at least the cables are good.

                  Can this happen because of a bad tcon board?
                  Or is it always a bad/shorted...

                  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...
