'86 zenith

[zeno]

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.
