    Sharp LC-70LE755U

    Just received a sharp 70 that has a weird bar across the screen, i have attached a photo sent to me before i got it, i have searched the forum for an hour but dont see any problems that seem to match it.

    thanks for any help in advance!

    Try reseating LVDS cable first.. Although it could be a panel fault I would me more susceptive that it could be a tcon board
    Did I leave the soldering iron on?

        The lines to the right of the sharp logo are panel failure. The left side bar may be panel failure as well, may be tcon related but I'm pretty confident it's the panel as well. You could.try reseating the flat white ribbon cable to that side if the LCD panel and see if it helps.

          It now shutoff while testing it and the power light is doing two (2) long blinks then three (3) short, is that error code 23?

            That's what I figured would happen eventually.

            Facing the back of the TV remove the right bottom ribbon going from the right side of the tcon to the panel is a flat white ribbon. If there's two of them one one side, disconnect both. Power up tv.

                What I would do now is strip the panel down so you can see the circuit boards that those ribbons connect to at the panel. Looking for a shorted SMD style MLCC capacitor. Most likely on the source driver that ran that side where that darker vertical bar was. You may find a problem on the circuit board in that specific area

                  Did you ever figure out what the problem was I have one that’s doing the same thing?

                    No I never stripped it down it does still work every day though and has not gotten worse.
