Amusingly, my AppleTV is currently the one thing that doesn't even though it used to - for some reason, with no changes, it just stopped turning on the TV. Switch 2 can happily turn on the TV though. Most peculiar.
(I've tried updating the AppleTV, replugging the HDMI cable, unplugging the HDMI cable for <period of time>, etc. Nothing has worked. TV does not have any network which means it can't have had any nefarious updates.)
Tried that without success. Also turned off Tailscale just in case that was keeping "alive" and the TV wasn't really getting a "I've turned on" signal - nothing doing. Investigations continue!
Might if I had an AV receiver. Apple TV is plugged directly into the TV. But the TV does have a weird junction box (consolidates all the connections into a single cable up to the TV, maybe it counts as an AV receiver) and it might be worth unplugging everything from that and that from the TV. Will give it a try.
