Install Cap Assy, High Voltage as shown.

TVSR Requirement:
1. Keep HV cable away from conductive
 parts 

(distance 

of 

1mm/kV).

2. Keep spacing between edge of anode
  cap & conductive parts (distance of
 0.5mm/kV).
3. Keep spacing between edge of anode
  cap & non-conductive parts
  (distance of at least 5mm or more).    

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:
Production side please ensure that the 
portion of HV cable above the Holder, HV 
Cable Combi is kept away from CRT's 
carbon area.
Also, portion of HV cable below the Holder, 
HV Cable Combi needs to be kept away 
from conductive parts (DGC, rotation coil, 
CRT's carbon area, speaker wire,
etc).
Ensure forming of HV cable is OK and no 
unnatural curve occurs. Do not twist or 
loop the cable.

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

5. Oscilloscope

2. Degausser

6. Landing Checker

3. DC Power Supply

7. XCV Adjuster

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. Loose the deflection yoke(DY) mounting screw, and set

the purity control to the center as shown below:-

3. Position VM coil as shown below:-

4. Set the raster signal of the pattern generator to green.
5. Move the DY backward and adjust the purity control so

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

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

screen becomes green.

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

confirm the condition.

8. When the position of the DY is determined, tighten it with

the DY mounting screw.

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

the screen, use magnet disc to correct it.

Preparation:
• Before starting, perform FOCUS adjustment.
• Picture Mode "CUSTOM"
• Receive dot/cross hatch pattern.

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:-

b) Horizontal Static Convergence
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:-

1. Receive cross hatch signal.
2. Set Picture to "MINIMUM", Brightness to "STANDARD".
3. Adjust the Y separation axis correction magnet on

the Neck Assembly so that the horizontal lines at
the top and bottom of the screen are straight.
