1988 TOL Zenith Digital System 3

I collected this very low hour set yesterday, and aside from some annoying issues, it works well. The picture quality is greatly enhanced by the tinted front glass and is unusually good for a CRT set. This set needs some work to be perfect. It has jailbars, and whenever a high contrast scene comes on, the picture is ripped and torn horizontally.

The vert IC has been NLA for years so board should be recapped
& resoldered. Streaks & jailbars prob from the usual cap in the
200 V supply and or CRT.

You'll also probably find bad soldering and leaking caps on the main boards that's inside a metal shield.

Zeno , your reference of the Verticle IC being NLA. I'm assuming that to mean Not Locally Available. Is that correct?

Usually stands for "no longer available".
