The Flyback Pots are Focus and Screen Controls you turn to adjust the Focus
and the G2 Level of the Picture.
They use to always be visible on the Back Cover with 2 Small holes, and you
place a small Screwdriver in there and adjust them, but your Zenith I
believe the Rear Cover has to be pulled to access these, and ideally it
ought to be done by a qualified Servicer.
The Focus on yours Is probably ok, so turning the G2/Screen control CCW a
little may get rid of the retrace lines. If not then it could mean the
Flyback itself is bad, or again the CRT. Sometimes also a component other
than the Flyback can cause it, so probably you need to find a Servicer in
your area who knows Zenith Brand Well
Not Sure where you are, but you can Try this Form online here and See what

I think it goes to the National Electronics Service Dealers Association in
N. America if your Zip code is 'other' and they try to recommend a
qualified Servicer based on what you write.

| Yes, it has 10 buttons grouped in pairs of 5. And, yes what you describe
as
