(CAUTION)
SHORT CIRCUIT THE ANODE OF THE PICTURE TUBE AND THE
ANODE CAP TO THE METAL CHASSIS, CRT SHIELD, OR CARBON PAINTED ON THE CRT, AFTER REMOVING THE ANODE.
WARNING!!
AN ISOLATION TRANSFORMER SHOULD BE USED DURING
ANY SERVICE TO AVOID POSSIBLE SHOCK HAZARD, BECAUSE OF LIVE CHASSIS.
THE CHASSIS OF THIS RECElVER IS DIRECTLY CONNECTED
TO THE AC POWER LINE.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY SHADING AND MARK ! ON
THE SCHEMATIC DIAGRAMS, EXPLODED VIEWS AND IN THE
PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE
THESECOMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. CIRCUIT ADJUSTMENTS THAT
ARE CRITICAL TO SAFEOPERATION ARE IDENTIFIED IN THIS
MANUAL. FOLLOW THESE PROCEDURES WHENEVER CRITICAL COMPONENTS ARE REPLACED OR IMPROPER OPERATION IS SUSPECTED.

2-11. REMOVAL OF ANODE-CAP
NOTE : After removing the anode, short circuit the anode of the picture tube and
the anode cap to the metal chassis, CRT shield or carbon paint on the
CRT.
• REMOVING
PROCEDURES
1 Do not dama
ge the surface
of anode-caps with
sharp shaped objects.
2 Do not press
the rubber too hard
so as not to damage the inside of
anode-cap.
A metal fitting called
the shatter-hook terminal is built into
the rubber.
3 Do not turn
the foot of rubber over too hard.
The shatter-hook
terminal will stick out
or damage the rubber
.
• HOW TO HANDLE AN ANODE-CAP
3 When one side of the rubber cap is separated
from the anode b
utton, the anode-cap
can be removed by turning up the rubber cap and pulling it up in the direction of the
arrow
c.
2 Using a thumb pull up the rubber
cap firmly in the direction
indicated by the arrow b
.
1 Turn up one side of the rubber cap in the
direction indicated
by the arrow a.

SECTION 4
SET-UP ADJUSTMENTS
• The following adjustments should be made when 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.
Controls and switches should be set as follows unless otherwise
noted:
PICTURE control ........................................................... normal
BRIGHTNESS control................................................... normal
Perform the adjustments in the following order :
1. Beam Landing
2. Convergence
3. Focus
Note : Test Equipment Required.
1. Color-bar/Pattern Generator
2. Degausser
3. Oscilloscope
...................................................................................................................................................................
Preparation :
• In order to reduce the influence of geomagnetism on the set’s
picture tube, face it east or west.
• Switch on the set’s power and degauss with the degausser.
4-1. BEAM LANDING
1. Input a white signal with the pattern generator.
Contrast
Brightness
2. Position neck assy as shown in Fig4-1.
3. Set the pattern generator raster signal to a green raster.
4. Move the deflection yoke to the rear and adjust with the purity control so that the green is at the center and the blue and
the red take up equally sized areas on each side.
(See Figures 4-1 through 4-3.)
5. Move the deflection yoke forward and adjust so that the
entire screen is green. (See Figure 4-2.)
6. Switch the raster signal to blue, then to green and verify the
condition.
7. When the position of the deflection yoke has been decided,
fasten the deflection yoke with the screws and DY spacers.

4-2. CONVERGENCE ADJUSTMENT
Preparation :
• Before starting this adjustment, adjust the focus, horizontal
size and vertical size.
• Set the Picture Mode to “STANDARD”.
• Cross hatch / Dot pattern.
4-2-1. Horizontal and Vertical Static Convergence
1. (Moving horizontally), adjust the H.STAT control so that the
red, green and blue dots are on top of each other at the center
of the screen.
2. (Moving vertically), adjust the V.STAT magnet so that the
red, green and blue dots are on top of each other at the center
of the screen.
3. If the H.STAT variable resistor cannot bring the red, green
and blue dots together at the center of the screen, adjust the
horizontal convergence with the H.STAT variable resistor and
the V.STAT magnet in the manner given below.
(In this case, the H.STAT variable resistor and the V.STAT
magnet influence each other, so be sure to perform adjustments while tracking.)
