    Testing LCD Tcon Pinouts

    Hi Guys,
    What is the best test for LCD TV Tcons other than replacing them with a good spare? I understand that the newer Tcons are able to be jumped with wireto display a test pattern. Not as easily as the the Plasma Tcons though.
    I have got Ebooks from several of the well known TV repair sites and its not there either. I tried Google got every thing except what I am looking for.
    Does anyone know what pin #44 of the LVDS wire cable is? What about pinouts to the TCON with the Dual Flat Ribbon Cablles?
    Thanks

      When you get the spec sheet of the LCD panel, it will give you the pin out and the requirement to run the T-CON, INVERTER, etc. There is no standard pin out for the LVDS connector.
      As you can see, the panel from the same manufacturer does not have the same pin out.

          Its a Shame the TV manufacturing companies can't agree on a standard. The Computer companies standardized the power supplies, USB, Serial ATA, main board card slot expansion slots. At least HDMI and Fiber connections are standard. Wouldn't our lives be a lot easier if it was standardized? You could build a TV as easily as a Computer! They almost stopped giving Schematics in Service Manuals because they want you to buy a new TV or replace the board instead of repairing it, in our Throw Away Society

              I agree, it is such a waste of earth resources.

                  At least they standardised on inverter pin out, more or less. LVDS might be standardised after the move to 4K or AMOLED

                      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...

                      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.

                      More Details

                      TV Model - LG OLED77G1PUA

                      Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

                      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...

                      Lg TCon test pins for screen test
                      by alltvrepairs
                      Hi,
                      i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.

                      Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.

                      Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?

                      Appreciate your help....
