TVSR Requirement :
1. Spacing between HV cable and other conductive part’s surface is
1mm/kV or more.
2. Spacing between HV cable's and enclosure with ventilation or the edge
where terminal bracket and rear cover meet: 10 mm or more.

CAUTION:
Do not overpull the wires during dressing --> avoid disconnection 
of wire.

The following adjustments should be made when a complete
realignment is required or a new picture tube is installed.

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

Picture control ......................................................... NORMAL
Brightness control ................................................... NORMAL

Perform the adjustments in order as follows:
1. Beam Landing
2. Convergence
3. Focus
4. G2 (SCREEN)
5. White Balance

Note: Test Equipment Required
1. Pattern Generator
2. Degausser
3. DC Power Supply
4. Digital Multimeter

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

degausser.

• In order to reduce the geomagnetism on the set's

picture tube, face it east or west.

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 below.

3. Set the raster signal of the pattern generator to green.
4. Move the deflection yoke (DY) backward and adjust the

purity control so that green is in the center and blue and
red are at the sides evenly.

5. Then move the DY forward and adjust so that the entire

screen becomes green.

6. Now switch over raster signal to red then blue and

confirm the condition.

7. When the position of the DY is determined, tighten it

with the DY mounting screw.

8. If the beam does not land correctly in all corners of the

screen, use magnet disc to correct it.

Preparation :
• Before starting, perform FOCUS adjustment.
• Picture mode STANDARD.
• Receive dot/cross hatch pattern.

Purity control
corrects this area.

Disc magnets or rotatable
disc magnets correct these
areas (a-d).

Deflection yoke positioning
corrects these areas.

1. (Moving vertically), adjust the 4 pole magnet to converge

red, green and blue dots in the center of the screen.

2. Tilt the 4 pole magnet and adjust static convergence to

open or close the 4 pole magnet.

3. When the 4 pole magnet is moved in the direction of

arrow A and B, the red, green and blue dots moves as
shown below:

If the blue dots does not converge with the red and green
dots, use the 6 pole magnet to adjust in the manner
described below.
