        Did you take a look at the ribbon connectors to make sure that there's nothing burned?
        Did I leave the soldering iron on?

            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...

            LG 82UN8570AUD ~ TCON or PANEL?
            by kca
            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...

            Samsung UN65TU8000 - Panel Issue [ hole in ribbon cable ]
            by NWArkGuy
            Well, I will be the first to admit that I screwed up...

            In attempting to replace the backlight in a UN65TU8000, I made a hole through one of the ribbon cables between the board that runs along the bottom of the back of the TV and the panel. This lead to a between a 1/4 to 1/2 inch vertical stripe running the full height of the image.

            I don't have the experience; personally, to solder a bridging wire for the paths that were cut. So, I have been on the hunt for other Samsung TV's of similar size.

            I have 2 that I have found and have in my possession. ...

            Missing LCD Panel Voltages VGH, VGL, VCOM (TCL 55P6US Sound & Backlight but NO Picture)
            by maneatingmonkey
            I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.

            There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.

            TCL 43S423 TCON OR PANEL FAULTY???
            by netgearnetgear
            Good day, I have a TCL TV: Model 43s423. After turning ON the TV, the ROKU TV logo appears with fine lines over the whole screen, then after a while there are vertical bands in the middle of the screen top to bottom and the TV tries to update its firmware but I do not have the remote to connect it to my new network connection. Also the Power ON light blinks 2 times in quick succession. When I remove the ribbon on the right of the tcon board the left side of the screen shows but with fine lines. If I remove the left side ribbon and connect the right side ribbon the whole screen is blank with...
