I forgot to state that I'm using an xfinity comcast digital/analog cable box, it works fine on the 1964 Zenith b&w 19" in my living room. So this should be providing a good signal to this little tv.
Though just for "I'm gonna try everything" I'll attempt to use a vcr to provide a signal to this tv.
Here's a better photo.
