    Sharp Aquos LC-70LE660U single horizontal line

    Hi folks, hope someone can give me some insight before calling a repair shop. My 17 month old (read: out of warranty) 70" Sharp has a single thin horizontal line about 12" up from the bottom. Very faint at the left edge, gradually darkening to the darkest spot about 2/3 across then growing faint again at the right edge. Called Sharp and they tried the "hold volume up and channel down while plugging TV in" which did absolutely nothing. Sorry Sir, call a repair shop. At the same time and possibly related, the HDMI 3 input became intermittent and then stopped recognizing any signal at all. Really looking for a home fix if possible. Edit: Same line on all inputs.

    Thanks for any help you can provide.

    Take a look at what Budwich says and there's plenty of information on this site (Badcaps) as he says on removing side tabs if it comes to that.

      UPDATE...Now TV powers on, "No Signal" flashes momentarily on the screen and then black. Power light remains constant but no video, no menu. Tried reset using input and vol - while plugging in but nothing. Been through many threads but can't find anything definitive. Not even close to understanding most of the jargon on here just wondering if I should even take the set to a shop or recycling.

        i got lucky with my codes....with tv unplugged hold down -v +c and power for around 20 seconds, and without letting go,plug it in....could the flaky hdmi port be a cold solder joint?...im not an expert lol,im just throwing that out there, some suggestions are better than no suggestions lol

          Repair shop called...it's the panel. Over $2000 to fix a TV that cost $1999. And the battle with Sharp begins...

            For the line? For the line, I'm afraid it's probably a faulty panel, even more so if there's a blob on the screen... At the least it's a tab bond issue...

            The no-signal message is probably the HDMI port or the main board...

              well... hopefully you have good luck with the battle with sharp. IF NOT, the tv can still be saved. there are a number of threads on the forum on how to go about saving the set for "free". Its an undetaking that requires DIY effort as NO repair facility would do it as it removes "design aspects" of the TV BUT it does bring it back to "full operation" such that you will likely not notice any problems. Anyways, if you don't get satisfaction from sharp, search thru the forum and see if you want to do the DIY stuff.

                Before ripping out the Y-TABS on the side of the screen.
                Check these Vdc on the Source PCB or the X-TAB on the bottom of the screen.
                Voff, CPV1, Von, VSTV1, STV, CPV2.
                Check and see if these voltages appear on the Y-TAB on the side of the screen.
                If not then there is a circuit break in the screen.
                Solder a thin insulated wire from the point on the X-TAB to the missing point on the Y-TAB.
                You may have to repeat this process for more than one of the above named points. This will sort your problem out.
