How to Wire a TV to behave like a real TV.

I wanna take a TV, put a Wire screen on it and give it a button to turn off and on. Simple, right? Nope! I want a plug to add to it as a ‘power source’. Thing is, my Wire knowledge is rusty and I’m too dumb to figure it out myself. Perhaps someone could give me a step-by-step thing for making one?

EDIT: Oh, and I don’t know which camera works for it, the regular or the Wire one, so please point that out for me?
