1953 Zenith - What to do now?

[mattcarranza]

Hey all, I just picked up what i believe is a 1953 Zenith. Powers on and was able to get someone what of a picture by running my cable box through it. Sound quality is perfect. Just wondering what could be causing the picture to not fully expand and clear up? Played with All the adjustments and this is the best i could get. Any input?

By the way, the film on the screen is from "To Kill a Mockingbird" in case anyone was wondering.

Thanks!
