Zenith System 3.

That sounds like bad electrolytic capacitors in the vertical circuit, is a common TV fault, and is worth fixing (provided the TV otherwise has a decent picture).

I've seen some Zenith's with a non-remote pushbutton varactor tuner. A friend had one that I replaced the 9-153 module in back in the mid '90's. His was a 25" console with two speakers below the CRT.
