    Help with sharp 70le650u

    Hello all thanks so much in advance for any insight. This thing is getting the best of me. About a month ago tv won't power on. Order a new power board. No dice. Both boards function the same. I do some research into the tcon.

    With my original tcon I take left cable off, left side of screen works and functions perfect. Take off right cable,nothing.

    Order new tcon. Left cable off left side black, right side of screen white. Right cable off nothing.

    2nd tcon. Left cable off, right screen has crazy colored lines. Right cable off, right screen white.

    3rd tcon. Works identical to my original tcon.

    I did a bit more research and replaced the lvds cable. No luck. At this point I don't know what to try. Any suggestions would be great. Thanks again!

      Maybe a little more troubleshooting and a little less throwing boards at it and you might get somewhere. Need some pictures. Better description of problem and some voltages
      I assume no responsibility for any stupid suggestions I might post.

          actually, you probably just need to do more reading of threads associated with sharp 70 sets... :-) your likely problem appears to be a "bad panel" as in tab driver. Lots of people have had success saving the set as it is not "repairable" as the side with the bad tabs need to have them all removed... they can't be fixed. As suggested, do some additional reading and go carefully from there.

            Thanks so much for the kind response. I will look into the known tab driver issue.

                Agreed. Sounds like the classic side horizontal driver issue. Your 2nd and 3rd tcons you purchased were bunk.
                Did I leave the soldering iron on?
