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.

Controls and switches should be set as follows unless otherwise noted:

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

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

Perform the adjustments in the following order :

1. Beam Landing

2. Convergence

3. Focus

4. White Balance

Note :  Test Equipment Required.

1. Color-bar/Pattern Generator

2. Degausser

3. Oscilloscope

In order to reduce the influence of geomagnetism on the set's

picture tube, face it east or west.

•

Switch on the set's power and degauss with the degausser.

1. Input a white signal with the pattern generator.

2. Position neck assy as shown in Fig3-2.

3. Set the pattern generator raster signal to a green raster.

4. Move the deflection yoke to the rear and adjust with the  purity

control so that the green is at the center and the blue and the red

take up equally sized areas on each side.

(See Figures 3-1 through 3-3.)

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

screen is green. (See Figure 3-1.)

6. Switch the raster signal to blue, then to red and verify the

condition.

7. When the position of the deflection yoke has been decided,

fasten the deflection yoke with the screws and DY spacers.

8. If the beam does not land correctly in all the corners, use a

magnet to adjust it.

(See Figure 3-4.)

Purity control
corrects this area.

Disk magnets or rotatable
disk magnets correct these
areas (a-d).

Deflection yoke positioning
corrects these areas.
