My apple TV 4 does this all the time, drives me nuts, Samsung TV and Apple TV combo seems like it's an issue. I'm debating on buying an extension cord and this:https://www.amazon.com/Uninex-Outle...1521119738&sr=8-3&keywords=on+off+wall+switch problem solved,I don't know who is to blame, Samsung (TV) or Apple, but this is happening all the time with my current setup. I have CEC enabled as well, because why not? It's super convenient and should work!
Somtimes when I shut off the TV, the Apple TV will go into stand-by as expected. After a couple of seconds the Apple TV LED will turn on again and stay that way for hours.
Actually I think it's a software problem with the Apple TV.
