Give complete “SERVICE REF. NO.” for
parts order or servicing. It is shown on the
rating plate at the cabinet back of the unit.
This T.V. receiver will not work properly in
foreign countries where the television
transmission system and power source differ from the design specifications. Refer to
the specification table.
1: An isolation transformer should be connected in the
power line between the receiver and the AC line
when a service is performed on the primary of the
converter transformer of the set.
2: Comply with all caution and safety-related notes pro-
vided on the cabinet back, inside the cabinet, on the
chassis or the picture tube.
3: When replacing a chassis in the cabinet, always be
certain that all the protective devices are installed
properly, such as, control knobs, adjustment covers
or shields, barriers, isolation resistor-capacitor networks etc.. Before returning any television to the
customer, the service technician must be sure that
it is completely safe to operate without danger of
electrical shock.
X-RADIATION PRECAUTION
The primary source of X-RADIATION in television receiver is the picture tube. The picture tube is specially constructed to limit X-RADIATION emissions. For continued X-RADIATION protection, the replacement tube must be
the same type as the original including suffix letter. Excessive high voltage may produce potentially hazardous X
- RADIATION. To avoid such hazards, the high voltage must be maintained within specified limit. Refer to this
service manual, high voltage adjustment for specific high voltage limit. If high voltage exceeds specified limits,
take necessary corrective action. Carefully follow the instructions for + B1 volt power supply adjustment, and high
voltage check to maintain the high voltage within the specified limits.
PRODUCT SAFETY NOTICE
Product safety should be considered when a component replacement is made in any area of a receiver.
Components indicated by mark in the parts list and the schematic diagram designate components in which
safety can be of special significance. It is particularly recommended that only parts designated on the parts list
in this manual be used for component replacement designated by mark . No deviations from resistance
wattage or voltage ratings may be made for replacement items designated by mark .

Service Information
Protection Circuit
This TV set has a built-in power supply protection circuit.
It is provided to protect the TV set in case of a power supply circuit malfunctions. When something abnormality
occurs during TV reception, the TV set goes to the stand-by mode.
When an abnormality occurs during TV reception, it causes pin 23 of the CPU to go continually Low for about
one second. The CPU detects that this has occurred and outputs the signal from pin 36 to switch off the power
supply lines.
Releasing the protective circuit and restoring power supply
To release the protective circuit and restore power supply, turn the power to the TV set OFF and then ON again
via either the main power switch or the ON-OFF button on the remote control. This will work only if the power
supply trouble was temporary. If there is permanent trouble such as a damaged circuit, power cannot be
restored and the circuit will have to be repaired.

Purity and Convergence Adjustment
CAUTION: The Convergence and Purity adjustments have been made at the factory. Readjustment
should be made only after picture tube or deflection yoke replacement, following the steps below:
Signals: Use a pattern generator which can output red,
green, blue and white raster and crosshatch
pattern signals.
Procedure: Carry out purity adjustment first, and then carry
out convergence adjustment.
Preparation: The deflection yoke may have several
correction magnets attached to its outer
edge. If replacing the picture tube, the
positions of the magnets can be changed and
they can be re-used, so remove these
magnets and keep them safely so that they
do not get lost.
PURITY ADJUSTMENTS
1. Place the picture so that its front faces west.
2. Insert the power plug into a wall outlet, and then turn on
the power for the TV and de-magnetize the TV using its
own degaussing circuit.
3. Loosen the screw which is holding the deflection yoke
(with integrated purity magnets), and then move the
deflection yoke forward as far as it will go. Remove the
rubber wedge at this time.
4. Turn off the red and blue raster so that only the green
raster is on.
5. Adjust the angle between the tabs (wings) on purity
magnets to center the vertical green belt in the picture
tube screen. (See Figures 2 and 3.)
NOTE: This adjustment can only be carried out by
changing the angle, not by rotating the tabs up and
down.
6. Gently move the deflection yoke back to the position
where the green band fills the whole of the picture tube
screen, and then tighten the screw to secure the
deflection yoke in place.
7. If there is any color distortion around the edges, correct
it by attaching magnets to the outer edge of the
deflection yoke. The magnets should be attached so
that the line running from the position of the distortion to
the center of the picture tube intersects the deflection
yoke. The colors on the magnets indicate the north and
south poles of the magnets. Attach the magnets in
whichever direction causes the distortion to
disappear.(See Figures 1 and 4. The south and north
pole positions are shown as a guide.)
8. Switch the screen to red and blue rasters and check that
there is no color distortion. If there is any distortion,
adjust the angles of purity magnets tabs or the forwardback position of the deflection yoke, or change the
attachment positions of the
correction magnets.

Purity and Convergence Adjustment
CONVERGENCE ADJUSTMENT
Preparation: After carrying out purity adjustment and
before proceeding to convergence
adjustment, provisionally insert the rubber
wedge so that there is no vertical or
sideways play in the deflection yoke.
Signals: Display a crosshatch pattern.
1. Red/blue center adjustment
Adjust the angle between the tabs (1) and (2) in Figure
5 and rotate them together until the lines of the red and
blue crosshatch patterns (vertical and horizontal lines)
are superimposed in the center of the screen.
2. Green and red/blue center adjustment
Adjust the angle between the tabs (3) and (4) in Figure
5 and rotate them together until the lines of the green
crosshatch pattern are superimposed with the red/blue
crosshatch pattern (vertical and horizontal lines) which
were superimposed in step 1).
3. Vertical lines at screen center (Red and Blue)
Use the VR2 control (see Figure 8) at the top of the
deflection yoke to correct the vertical line convergence
at the center of the screen.(See Figure 9.)

4. Vertical lines at screen top and bottom
Use the VR1 control (see Figure 8) at the top of the
deflection yoke to correct the vertical line convergence
at the top and bottom of the screen. (See Figure 10.)
5. Horizontal lines at screen top and bottom
Rotate the Deflection yoke to the left or right to correct
the horizontal line convergence at the top and bottom of
the screen. (See Figure 11.)
If vertical lines are intersecting at the top and bottom,
use a screwdriver to adjust the Balance coil at the top of
the deflection yoke. (See Figure 12.)
