Could a 12v deep cycle battery power a tv with a 20″ or larger screen?

I’m looking for a way to power a small to medium sized television in a place with no electricity. This is for a temporary outdoor art installation. So I was wondering if a 12v deep cycle battery would do the trick? Maybe if it was hooked up to a small solar panel? I don’t care if it only works on sunny days. Has anyone tried this? Or does anyone know of a better way?
