CONVERGENCE ADJUSTMENTS
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. 4) and turn them to magenta (red/blue).
3. Using 6-pole convergence magnets, overlap the magenta(red/blue)
and green lines in the centre of the screen and turn them to white.
4. Repeat 2 and 3 above, and make best convergence.
DYNAMIC CONVERGENCE ADJUSTMENT
1. Using the Y VR on the deflection yoke, match the Y
H
5 and 8)
2. Using the Y VR on the deflection yoke, match the Y
V
3. Repeat the steps 1 and 2, obtain an optimum convergence.
4. Differential 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. 7, adjust the X
ence by using the differential coil on the top of the deflection yoke
(Fig. 8) so as to minimize the X
•
After adjustment, fix the wedge at the original position.
Fasten the retainer screw of the deflection yoke.
Fix the P/C magnet with glue.
