6. SERVICE ADJUSTMENTS
PURITY
1. Display a monochrome pattern. ;
2. As viewed from the back (See Fig. 6-1), turn the magnet
lock counter-clockwise to loosen it.
3. Turn the green cutoff VR (R711) fully clockwise
and the red and blue cutoff VRs (R712, R710) fully
counter-clockwise. (Fig. 6-3)
Adjust the screen VR (Fig. 6-3) so that the vertical green
band becomes easy to see.
4. Loosen the deflection yoke securing screw and slide the
yoke fully rearward to obtain colour shading in the
green disk. (Fig. 6-2)
5, Overlap the two purity magnet tabs and set them to
12 o'clock position.
6. Open and close the two purity magnets (scissor fashion)
and adjust so that the green disk is positioned at the
center of the picture. (Fig. 6-2)
If green disk is not obtained, adjust for uniform overall
coloration.
7. Slide the deflection yoke forward and adjust its posi-
tion so that the green colour completely fills the picture
area.
8. Confirm that uniform overall rasters of both red and
blue single colour rasters can also be obtained in the
same manner.
9. Secure the deflection yoke retaining screw moderately
so that the deflection yoke does not move back and
forth.

STATIC CONVERGENCE (CENTER)
1. Employ a crosshatch pattern and adjust the brightness
so that the image is clear, but slightly darkened.
2. Turn the red and blue cutoff VRs fully clockwise and
the green cutoff VR fully counter-clockwise (Fig. 6-3).
Adjust the screen VR (Fig. 6-3) for an easily seen image.
3. Adjust convergence roughly in the corner by tilting
the deflection yoke vertically or horizontally, then
insert a wedge between the yoke and CRT on top.(Fig.6-7)
4. Turn the two 4 pole convergence magnets and adjust
so that red and blue become overlapped throughout
the picture area to yield magenta. (Fig. 6-5)
5. Turn the green cutoff VR fully clockwise and adjust the
two 6 pole convergence magnets so that the green and
magenta become overlapped throughout the picture
area to yield white. (Fig. 6-4)
6. Repeat steps 4 and 5.
