Re: Sharp LC-70LE757U Flashing 2-5 :-( can it be saved economically?
If someone can chime in and help out. Trying to fix a Sharp LC-70Le867U. Tv would not even turn on, 2 long 5 short code. Pulled it apart getting 120v in and 12v out with 5v of stand by on the power supply board. But still wouldn't start up. Started reading about the led side driver going bad, so started pulling ribbons from the t con board. Sorry I am an electrician but never messed with circuit boards or TVs, so if I'm calling something by the wrong name or misspeaking cut me some slack please. When I pulled ribbons for each half of tv, both had vertical lines on the dead side. But decided to reseat ribbons while tv was already on. To my amazement everything worked perfect, tv would turn off and on for awhile no prob but eventually after letting it sit started doing the same code. First question what did I temparily bypass? And second what do I need to fix?
