This adjustment should be performed
after the purity magnet adjustment.
1. Receive “CROSSHATCH PATTERN” signal.
2. Set. the Brightness control and Contrast control
at MAX position.
STATIC CONVERGENCE
3. Adjust the opening degree of the 4-pole
magnet and rotate the magnet to converge
red and blue lines.
4. Adjust the opening degree of the 6-pole
magnet and rotate the magnet to converge
red, blue and green lines.
DYNAMIC CONVERGENCE
5. Dynamic convergence (convergence of the
three colour fields) at the edges of CRT screen
is accomplished in the following manner.
Convergence in Fig. a:
insert wedge”a” between the deflection yoke
and CRT, and tilt the deflection yoke upward
until the mis-convergence shown in Fig. a is
corrected.
Convergence in Fig. b:
Insert wedges “b” and “c” between the
deflection yoke and CRT, and tilt the
defllection yoke until the mis-convergence
shown in Fig. b is corrected.
Convergence in Fig. c:
Insert wedge “c”
deeply between the
deflection yoke and CRT, and tilt the
deflection yoke to right until the mis-
convergence shown in Fig. c is corrected.
Convergence in Fig. d:
Insert wedge
“b” deeply between the
deflection yoke and CRT, and tilt the
deflection yoke to left until the mis-
convergence shown in Fig. d is corrected.
6. Stick the three wedges onto the CRT, and
apply glass tapes thereon.
7. Apply lacquer to the deflection yoke screw,
magnet unit (made of purity, 4-pole and 6-
pole magnets) and magnet unit screw.
After the adjustment,
receive either the Red or
the Blue signal and check that there is no mixture
with the other colour signal.
