First off dont drive the brite & contrast hard. It can throw
things off. Especially while doing the CRT set up !
You can try some correction magnets. They are taped or
glued to the bell near the corners. You put up a pure
green only raster as best you can. You put it on the
bad area & move it in & out also turn it to get the best
correction. When you are happy tape it down.
Dont try it with a B&W raster, you will go nuts ! I
dont remember the style Zenith used but look inside to see
if any fell off.

Also, don't go near the back of the CRT with the degausing coil. The stick on magnets demagnetize real easy.
