    LCD T-con board schematic

    I recently discovered a schematic for LCD panel T-con; AU Optronics T260XW02 with built in COF.

    From this, several assumptions I've previously made appear true:
    - The left-most tab is used to get the signals to the side tab bonds for controlling the panel rows. This may explain why the left most tab most often fails, as it is under more stress than the other tabs.
    - The side bonds use only VGH (+25V), VGL (-10V), data, clock and output enable (they are shift registers)
    - VGH appears to be modulated on this panel -- I'm not sure why!
    - The main chip on the T-con appears to most only handle translation and synchronisation of the signals, it doesn't appear to do any picture processing

      I found it while searching for pictures of a particular t-con board.

        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.

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

        Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
        by Tynan Dill
        I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

        Upon bringing it home and plugging it up, it showed a standby light.

        I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

        The screen seems to blackout and stay black, but with a flashlight I can see the display.

        With my Playstation 4 connected via HDMI, and running a game I can hear sound.

        Assuming...

        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...

        DELL Latitude 5430 Rugged CORE_D5K Rev.A00 Schematic and/or Board View
        by Garret Matt.
        Hello,

        I'm Working on replacing an Inductor on this Dell's board and I need to come up with a compatible replacement. As much as I would like to smash a comparable 2R2 in the same spot I'd like to confirm the specs before confirming a killed board. For my purposes I'd be happy with a second opinion on the replacement inductor or the actual schematics/board view. As this is a commonly used Dell Rugged in my local service area, schematics would greatly help in the future.

        Thank you in advance for any assistance you can render.

        looking for schematic for Acer SP313-51N board Yacht_TL 203022-1
        by johnbeton
        Hello,

        I'm looking for the schematic for a Acer board Yacht_TL 203022-1
        The board had some minor liquid damage.
        I have no shorts, have 3v, 5v, 3.3v, ... but no leds or power on.
        When touching certain parts of the board with my finger, the powerleds go on or start blinking.
