My TV has stopped responding to both my remote and onboard buttons.
My Sharp TV (LC55P6000U, G172055) suddenly stopped responding to remote commands with the exception of the power button. Now the onboard controls as well (except power). I did a hard reset on both the TV and the remote. It powers up, but if any button is pressed (whether remote or onboard) a spinning icon (waiting/busy/buffering) appears for a few minutes and then just disappears.
If I have my Xbox turned on, the TV will display it when powered up. But I can’t change volume or access menu etc… The remote has good batteries and the IR is working (checked through phone camera). I’m stumped! Is this a failing board? A known quirk?? Any help is greatly appreciated!
