TIONAND PRODUCT SAFETY NOTICEON PAGE 3 OF THIS MANUAL.
SET-UP ADJUSTMENT (FOR 13”, 14”, 19”, 20”)
s The following adjustments should be made when a complete realignment is required or a new picture tube is installed.
Perform the adjustments in order as follows :
1. Color Purity
2. Convergence
3. White Balance
Note: The PURITY/CONVERGENCE MAGNET assembly and rubber wedges need mechanical positioning.
Refer to figure 1.
Mounting position of the purity magnet assembly should fit to same position as old one because slightly difference to
the position depen on a kind of tube.
* There are no adjustment of purity and convergence in some picture tube (Unified with purity magnet)
COLOR PURITY ADJUSTMENT
NOTE : Before attempting any purity adjustments, the receiver
should be operated for at least fifteen minutes.
1. Demagnetize the picture tube and cabinet using a degauss-
ing coil.
2. Set the brightness and contrast to maximum.
3. Use a green raster from among the built-in test signals.
4. Loosen the clamp screw holding the yoke and slide the
yoke backward or forward to provide vertical green belt
(zone) in the picture screen.
5. Remove the Rubber Wedges.
6. Rotate and spread the tabs of the purity magnet (See fig-
ure 2.) around the neck of the picture tube until the green
belt is in the center of the screen. At the same time, enter
the raster vertically.
7. Slowly move the yoke forward or backward until a uniform
green screen is obtained. Tighten the clamp screw of the
yoke temporarily.
8. Check the purity of the red and blue raster.

s CENTER CONVERGENCE ADJUSTMENT
1. Display built-in cross-dot pattern using the TEST SIG-
NAL SELECTION function.
2. Adjust the BRIGHTNESS and CONTRAST Controls
for well defined pattern.
3. Loosen the tightening ring and adjust two tabs of the
4-Pole Magnets to change the angle between them
(See figure 3.) and superimpose red and blue vertical
lines in the center area of the picture screen.
(See figure 4.)
4. Turn the both tabs at the same time keeping the con-
stant angle to superimpose red and blue horizontal
lines at the centre of the screen. (See figure 4.)
5. Adjust two tabs of 6-Pole Magnets to superimpose red/
blue line with green one. Adjusting the angle affects
the vertical lines and rotating both magnets affects the
horizontal lines.
6. Repeat adjustments 3, 4, 5 keeping in mind red, green
and blue movement, because 4-Pole Magnets and 6-
Pole magnets interact and make dot movement com-
plex.
7. After completing the CENTER CONVERGENCE AD-
JUSTMENTtighten the tightening ring to fix the mag-
nets.

s Xv COIL ADJUSTMENT
Adjust the Xv coil (on the deflection yoke) to correct
misconvergence at both sides on screen.
Use a hexagonal tip stick (plastic) to adjust the core of
coil.
s SCREEN-CORNER CONVERGENCE
When the misconvergence is still evident on corners even
though the above adjustment is done, use the ferrite sheet
(Part No. 23993622) to correct misconvergence.
1. Put ferrite sheets into the space under the yoke.
Decide such position that misconvergence becomes
minimum, watching picture screen. (See figure below.)
2. Remove cover paper of ferrite sheet to stick it in the
place on the tube. Put adhesive tapes on ferrite sheets
to fix.
