    Sony KDL-32L4000 bad t-con or panel?

    I've got a KDL-32L4000 that displays this weird image (see photo). Sorry about the picture quality, was holding the TV with one hand and taking a photo with my smartphone in the other.

    About the third of the screen is sharp and static, the rest is moving like it's being refreshed constantly one over the other sort of like a ghost.

    Is there a way to find the culprit without actually replacing the t-con as I'd have to order one.

      Looks like maybe panel problem. May try flexing panel and see if any change
      I assume no responsibility for any stupid suggestions I might post.

          To flex it properly, I'd have to remove it from the bezel. Tried flexing it while still inside the TV frame with no results.

          I'll see, if I can make a video of the problem and post it on YT.

              +1 for panel.

              you can confirm by opening the back, disconnecting one side of the t-con that connects to the panel. powering the set up and checking picture, then repeat for the opposing side.

                  If I remove the flat cable, there's no picture, only the backlight is on.

                      the ribbon that goes to the panel? not the lvds that goes from the main board to the t-con.

                      is there 1 or 2 cables?

                          There's just one flat cable that goes from the t-con to the LCD so I can't really do what you suggested.

                              well, that ruined that idea.

                              i'm still looking at panel. if you want to pull it down to the panel and apply pressure to the tab bonds to see if it is causing the fault, then it is your call. nothing to lose in my opinion though.

                                      Ah well, it's not very likely that I'll be finding a compatible panel any time soon. I'll just use it for parts. Cheers guys.

                                          Hard to tell by the pic., you could try a firmware update, might work, sometimes the firmware gets buggered up. Tcon boards are readily available and usually pretty reasonable in price.

                                              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...

                                              Hello all ~

                                              Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.

                                              When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.

                                              I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped...

                                              Hi, hoping for some views on this one which I've not come across before. The TV generates an image that has 12 noticeable bands across it. The image is still there and accurate, but the colour (or perhaps the brightness) changes gradually across each band which creates a noticeable 'step change' at the edge of each band. Given it's a 4K TV with 2160 rows of pixels, I'm guessing the 12 bands correspond to 12 gate drivers of 180 rows each. If this guess is right, then perhaps:
                                              a) all the gate drivers are malfunctioning the same way (which seems unlikely), or
                                              b) the Tcon board is malfunctioning,...

                                              Sony KD-65A1 Repair – 4 Red Blinks Error
                                              by AK_777
                                              Hi everyone!
                                              I have a Sony KD-65A1 TV with a fault – 4 red LED blinks. After disassembly and visual inspection, I found that the G76 power board and DKA board had been replaced. It is also possible that TCON was replaced, but I am not sure – there are a few marker marks that could be factory-made.

                                              Based on assumptions, the previous service attempted to solve the issue by replacing potentially faulty components. I decided to investigate further, found a service manual, and figured out a way to power up the power supply unit autonomously and put the OLED panel and...

                                              Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...
