HV- 29LPZ

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 shown in Fig. 4)

3.Using the VR1 on the deflection yoke, match the YH (CROSS). (See Fig. 3 and 6)

4.Using the VR2 on the deflection yoke, 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.
