A newby with a question

[suede]

So i just bought a 1957 zenith super royal with the swivel base in pristine exterior condition. When i turn it on it gets a "picture", well whatever you call the "snow".

So ive tried to hook its vhf hookup up to cable and to a dvd player (as there are no wires to connect to the uhf part, and it looks like none were ever there). Well the picture doesnt come in, just the snow with an occasional glimpse of a picture and no sound.

What should i try next? Opening up the back to see if there are uhf cables that have simply fallen into it or???

Sorry, im just getting into this. Any help would be appreciated. Id love to sit back and watch some old tv programs the way they were meant to be seen, on a tv of the era.
