Viewsonic G810 Focus Problem
 

Installed new flyback to restore high voltage. Now can't get good focus.
When focus is good in center, it's poor on sides & corners.
When it's good on sides & corners, it's poor in center.
This is the first G810 I've ever repaired. CRT seems good & strong
with great grey scale.

Thanks in advance.

Sounds like you got the two focus leads swapped, check the wires that go
to the neck board, colors can be deceptive, try swapping the two focus
leads and see what happens. Make sure you don't swap the G2 with one of
the focus though.
