The power supply board is shot.....same thing happened to mine which was only 18 months old. I was not happy. Called sharp and they were no help since it was out of warranty. Ended up buying a Vizio to replace it. But the good news for you is you can buy a power supply board for $40-$60 offline and its a very easy fix. I did it just yesterday to keep the TV as a basement TV. Literally took me 10 minutes and most of that time was taking out/replacing all the screws for the back panel.
Sorry, there was a problem. Please try again later.Same thing happened to my TV after less than 2 years. Hisense/Sharp support was zero help but I fixed it with a new power supply board. It was about $50, part number RSAG7.820.7707/R0H (picture attached) and it took me about an hour to replace.
Sorry, there was a problem. Please try again later.Within just a few months my TV was shutting itself off. I called them and they said do a factory reset which in its own right was very difficult to do because it was hard to get it to stay on long enough. Eventually I unplugged it for a day and started it back up then did a factory reset and now whenever I’m done I unplug the TV until I use again
