SET-UP ADJUSTMENTS
a complete realignment is required or a new
picture tube is installed.
@ These adjustments should be performed with
rated power supply voltage unless otherwise noted.
The controls and switch should be set as follows unless
otherwise noted :
PICTURE

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

LANDING
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 in
Fig.2
3. Turn the raster signal of the pattern generator
to green.
4. Move the deflection yoke backward, and adjust
with the purity control so that green is in the
center and red and blue are at the sides evenly.
(Fig.3)
"Move the deflection yoke forward, and adjust so
or
that the entire screen becomes green. (Fig.1)
o
Switch over the raster signal to red and blue and
confirm the condition.
