Dress Lead Assy, Speaker to center position of Rotation coil Make sure Earth assy,
Coating wire is above Lead Assy, Speaker This is to keep Lead Assy, Speaker away from Deflection Yoke.

Keep wires away from

heatsinks A007, D604 and

conductive parts

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).

Caution: 1) Make sure the specified position is being followed.
 

2) Position the Cap Assy, High Voltage in the inner ring of the

 

  Holder, HV cable combi (see diagram).

Install AC cord holder to AC power cord at specified position as shown.

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 bracker and rear cover meet:10mm or more.

Caution:
-  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 for ming of HV cable is ok and no unnatlural curve occurs.

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.
