Apple TV won’t shut down and remote stopped controlling volume.
I’ve tried resetting both TV and remote, unplugging tv, recharging remote, and every other troubleshooting method online. Every time, it goes black and then displays either one of two screens, both indicating “no signal”. I’ve changed the output as well but only HDMI 4 works. Seems like everything else is working (except volume and shut down). Previously if we left the tv on for too long we’d get this message but could always shut down and restart. Nothing seems to work. Even after unplugging.
