5. After completing the red and blue center
convergence adjustment, locate the pair of
6-pole magnet rings.
6. Rotate the individual rings (change the
spacing between tabs) to converge the vertical
red and blue (magenta) and green lines.
7. Rotate the pair of rings (maintaining the
spacing between tabs) to converge the
horizontal red and blue (magenta) and green
lines. Don't rotate the 2-pole magnets as they
adjust for color purity.
8. Mark the correct position for the magnets and
apply a small line of glue to hold the magnets
in place. Lock the rings in place.
6-4-2 Dynamic (Edge) Convergence
Use the following procedure to correct minor
dynamic (edge) misconvergence. If, after using
this procedure, dynamic misconvergence around
the periphery of the display area is still greater
than the tolerance, contact the Regional After
Service Center for possible CRT replacement.

1. Make sure the display is not affected by
external magnetic fields.
2. Make sure the static convergence is properly
adjusted.
3. Strategically place small rubber magnets on
the back of the CRT to correct the
misconvergence. Be careful not to remove the
paper protecting the adhesive on the magnets
until you are satisfied with their placement
and the dynamic convergence.
4. When you are satisfied with the convergence
around the edge of the CRT, permanently glue
the magnets to the back of the CRT.
WARNING: Do not remove or change the
position of the factory installed
wedges. These wedges were
!
installed by the CRT manufacturer
and are properly placed for this
CRT; their removal may result in
damage to the CRT.
