If there TV, if they function of switching at a given time select this option (usually you can configure the remote control). Of course, not to forget also configure the current date-time and check the safety settings in case of power loss. The only thing - I don't know if this way to start a playlist.

1. To buy a cat a timer that will turn on / off the TV itself. Forbid to touch the plug nailed (suspended). But all the TVs, of course, if such inclusion will go to the mode you want depends on it.
2. To get a thing from Xiaomi - a kind of thing that can receive commands over the Internet, and pass them as a normal remote. There are probably other manufacturers.
