STATIC CONVERGENCE ADJUSTMENT
1. Input a crosshatch signal.
(FRONT VIEW)
2. Using 4-pole convergence magnets, overlap the red and blue
lines in the center of the screen (Fig.1) and turn them to
magenta (red/blue).
3. Using 6-pole convergence magnets, overlap the magenta
(red/blue) and green lines in the center of the screen and turn
them to white.
4. Repeat 2 and 3 above, and make best convergence.
I After adjustment, fix the wedge at the original position.
Fasten the retainer screw of the deflection yoke.Fig.1
Fix the 6 magnets with glue.

ADJUSTMENT
After adjusting purity & static convergence.
1. Move the deflection yoke up and down to adjust the pin cushion
distortion in the screen top and bottom. (See Fig. 2)
BOTTOM
2. Move the deflection yoke left to right to overlap the lines in the

periphery, and match the Yv.(See Fig. 3)
3. Repeat the steps 1 and 3 and obtain an optimum convergence.
