 Do not squeeze the rubber covering too hard to avoid damaging the

anode-cap. A material fitting called a shatter-hook terminal is built
into the rubber.

 Do not force turn the foot of the rubber cover. This may cause the

shatter-hook terminal to protrude and damage the rubber.

NOTE: Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield or carbon painted on the CRT, after

removing the anode.

H.V. remains in the CRT even after the power is disconnected. Discharge the CRT
before attempting to remove the anode cap to avoid electrical shock. Short between
the anode and CRT coating the earth ground strap.

   The following adjustments should be made when a complete
realignment is required or a new picture tube is installed. These
adjustments should be performed with rated power supply
voltage unless otherwise noted.

The controls and switch should be set as follows unless
otherwise noted:

PICTURE control ................. normal

BRIGHTNESS control ......... normal

• Feed in the white pattern signal.
• Before starting, degauss the entire screen.

1. Input a raster signal with the pattern generator.

2. Loosen the deflection yoke mounting screw, and set the purity

control to the center as shown in Fig.2.

3. Turn the raster signal of the pattern generator to green.

4. Move the deflection yoke backward, and adjust with the purity

control so that green is in the center and red and blue are at the
sides evenly. (Fig.3)

5. Move the deflection yoke forward, and adjust so that the entire

screen becomes green. (Fig.1)

6. Switch over the raster signal to red and blue and confirm the

condition.

7. When the position of the deflection yoke is determined, tighten

it with the deflection yoke mounting screw.

8. When landing at the corner is not right, adjust by using the disk

magnets. (Fig.4)

 Perform the adjustments in order as follows:

1.

Beam Landing

2.

Convergence

3.

Focus

4.

Screen (G2) and White Balance

Disk magnets or

magnets correct

these areas(a-d).

Deflection yoke positioning

corrects these areas.

If the blue dot does not converge with red and green dots, perform
the following steps:

• Move BMC magnet (a) to correct insufficient H. Static conver-
gence.

• Rotate BMC magnet (b) to correct insufficient V. Static conver-
gence.

In either case, repeat Beam Landing Adjustment.

• Before starting, perform Horizontal and Vertical Static

Convergence Adjustment.

1.

Slightly loosen deflection yoke screw.

2.

Remove deflection yoke spacers.

3.

Move the deflection yoke for best convergence as shown
below. ( Fig. 8)

4.

Tighten the deflection yoke screw.

5.

Install the deflection yoke spacers.

• Before starting, perform FOCUS, V. LIN and V. SIZE

adjustments.

• Set BRIGHTNESS control to minimum.
• Feed in dot pattern.

1.

Adjust V. STAT magnet to converge red, green and blue dots in

the center of the screen.  (Vertical movement)

Tilt the V. STAT magnet and adjust static convergence to open or
close the V. STAT magnet.

2.

When the V. STAT magnet is moved in the direction of arrow a

Affix a permalloy assembly corresponding to the misconverged
areas:

1.      Adjust FOCUS control for best picture.

1.

 Input a dots pattern.

2.

 Set the PICTURE and BRIGHT controls at minimum
 and COLOR control at normal.

3.

 Adjust SBRT, GCUT, BCUT in service mode with an

oscilloscope as shown in Fig. 11 so that voltages on the
red, green, and blue cathodes are 170Vdc.

4.

Observe the screen and adjust SCREEN (G2) VR
to obtain the faintly visible background of dot signal.
