Hi fault as title above, thick vertical line in the centre of TV, I’ve changed the TCON board but it hasn’t fixed the problem, is there any point in changing the main board? Thanks.
either a ribbon cable came loose or it got damaged. you will need to check which.
@gibbsy what you have here is a disconnected ribbon that enters the LCD from the LCD driver board. Those ribbons are attached via a special process. Gently push on the ribbon cables that enter the LCD right where the fault is. If it changes the line you know the issue is the separation of the ribbon cable from the LCD. If it does not then it “could” be originating from LCD driver board. That is the board that connects to the LCD screen. WE would need to get the manufacturer number or any other identification on this, so we could try and check for some schematics. Let us know what exact panel your TV has. There is a label on the back of the panel that will have all the information on it. None of this will be easy to do and it will require a complete disassembly. If you want to give it a try, post some really good pictures of that board with your QUESTION so we can see what you see and hopefully help you further. If you feel it’s to much or to far out, replacing the LCD will be the only other option. Panels that size are not easy to come by and will most likely cost more than a new TV.

Hi old Turkey I’m going to upload some pics of the layout of the TV, just the boards on the chassis I’m not even sure if there is a board behind the panel, I seen someone strip down a TV, to get to the led backlights, is there a board even further behind than that, doesn’t seem there would be much room. So uploading the pics to let you see, I know the repair shop said it was those ribbons, but is there a possibility the main board could be causing the fault? The picture with all the boards isn’t great, but I’ve broke it down a bit, and you can see the yellow ribbons the repair shop was referring, they look like they just connect to the LCD so not so sure there’s another board in play, but hope you can see the long thin one I spoke about in previous posts, Thanks.
