If your TV is "smart" and will eventually be connected to the internet it's possible that the maker might be able to provide an IP address when and if that happens. Don't know if they could or would do that though.
Not sure what country you live in, but in the US, most stolen TVs wind up in pawn shops for quick cash. If you are in the US, you need to advise all local pawn shops of the theft. I'm assuming you already notified the police as the guy above said. We can't track anything not knowing what area you are in and keep an eye on things like Craig's List ads.
