Sounds like you need to get into home automation. A Smartthings hub and an smart outlet and your set. It would work by both a timer and Alexa voice for override, I love saying "computer"(yup they added it as a wake word) turn on TV and having my screen come down, projector turn on and sound system fire up. You can also pause and change channels with Alexa and a Harmony remote.
And the harmony remote will tie into ST and turn on/off the outlet automatically for you.
