    Scoping the LVDS Connector

    I am working on a Toshiba 32HL86 which has sound and backlight but no pic. The tcon is buried and looks to be a pita to get at.

    I was wondering if there was a way to reliably ascertain if the video signal was reaching the lvds connector. Seems like it might come in handy whether or not your tcon is readily accessible.

      You may have signal at pcg but that will not tell you if lvsd lead or tcon faulty.

          Good way to differentiate between a bad main or a bad tcon though.

              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...

              No LCD image after connector replacement – lifted components and damaged resistor (Nintendo Switch Lite HDH-CPU-02)
              by Tomylee
              Hi everyone,

              Sorry for the person who’s going to read all this !
              I'm on a Nintendo Switch Lite, motherboard HDH-CPU-02.

              While replacing the left joystick, I had to remove the motherboard to access the connector underneath. When I lifted the LCD connector latch, it broke (the plastic had become brittle over time), so I replaced the entire connector.

              During the desoldering of the LCD connector using hot air, three small components located just below the connector (likely 0402 capacitors) came off and remained stuck to the bottom of the...

              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...

              Best way to solder LVDS connector for beginner (and qfn) ?
              by corrize
              Hello, I'm a beginner for micro soldering. Right now I have some difficult to solder a qfn 20, I guess I put too much solder on the thermal-ground pad, the result is a corner of chip wich don't touch the board (last try).

              I use a wire solder with hot air, I tin the board and chip before with iron and I use good flux.

              I will have to solder a LVDS connector (40 pins, laptop pc), I saw a solder paste in seringe, good quality (it does not scatter).
              See the test :

              With hot air from bellow the board, that's...

              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...
