STATIC CONVERGENCE ADJUSTMENT
1. Input a crosshatch signal.
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.
●
After adjustment, fix the wedge at the original position.
Fasten the retainer screw of the deflection yoke.
Fix the 6 magnets with glue.
DYNAMIC (periphery) CONVERGENCE
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)
2. Move the deflection yoke left to right to overlap the lines in the
periphery, and match the Yv(VR1).(As s hown in Fig. 4)
3. Using the VR1 on the deflection yok e, match the Y
H
(CROSS).
(See Fig. 3 and 6)
4. Using the VR2 on the deflection yok e, match the YH (BOW).
(See Fig. 3 and 6)
5. Repeat the steps 1 and 4 and obtain an optimum convergence.
6. Differential(XV) coil ADJUSTMENT.
In case where the horizontal lines of red and blue around the
center of both sides of the picture as shown in Fig. 5, adjust the
XV difference by using the differential coil(XV coil) on the top of
the
deflection yoke (Fig. 6) so as to minimize the XV difference.
