    Element EUFT551 No Video

    Turns on with backlight and no video. Removing two ribbon cables one side at a time shows white on the disconnected side. Can't confirm if there is audio. Tcon fuse measures 12.9VDC on both sides of the fuse.

    Will be trying a new tcon board unless there are any other suggestions.

    Update: Ordered a new tcon since it was only $20 at electroparts ebay store. This 4K TV uses the same AUO panel as a Sony XBR-55X900A

    Start checking Voltage at the test points on the t-CON board, pictures are too blur to see the test points clearly.

      New tcon board fixed it. Checking the backlight settings on this model, with tv on, source-2-5-8-0. Backlight for Energy Saving mode (default on reset) is 34/100 and Standard mode is 58/100. Shouldn't get backlight issues unless you change it to Dynamic.

        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 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...
