    Intermittent malfunction lg 47lg70

    Hello

    I have a question. Before ordering a new t-con and possibly destroying my tv by taking it apart to replace it I need to know one thing. Is it the t-con? Or maybe loose cables? Or anything else.

    This is what happens. One day it's working perfect. Then half way through the day or another day or even weeks later it goes nuts. The black color stops working. Anything black on the tv has purple lines. Then another day it's working fine again.

    Anyone know what it is? Or could be?

    Could be a loose lvds cable Or more famously one of LGs famous BGA soldering connections on the main processor on mainboard.
    Did I leave the soldering iron on?

        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...

        TCL 50S535 bad tcon or panel issue?
        by x_orange90_x
        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...

        Driving a Sharp TCON/panel with a universal main board
        by advant
        This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

        I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...

        LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
        by Hakuu
        Hi There,

        This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

        After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

        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...
