How to fix tv connections?

Okay, about a month ago I rented my basement to some people I knew. Later, they thought we weren't gonna give them there money back, and they robbed us. They took my biggest flat screen and other little stuff. I don't really care about the tv in genroul, but my signal got cut off. They untagngled the wires neatly when they took it to. When I went to turn on my other TVs, they ALL said, "no signal" and that's it, I have direct tv by the way. (be specific when your describing things to me to please like, it's color, shape, and mass, stuff like that, thanks) please help me, I muss my tv. :(
