SAFETY PRECAUTIONS

C-13310
C-13311

1. The design of this pr oduct contains special hardware, many
circuits and components specially for safety purposes. For
continued protection, no changes should be made to the
original design unless authorized in writing by the manuf acturer.
Replacement parts must be identic al to those used in the
original circuits. Service should be perf ormed by qualified
personnel only.

2. Alterations of the design or circuitry of the products should not
be made. Any design alt erations or additions will void the
manufacturer's warranty and will further relieve the
manufacturer of responsibility for personal injury or property
damage resulting therefrom.

3. Many electr ical and mechanic al parts in the products have
special safety-related characteristics. These characteristics are
often not evident from visual inspection nor can the protection
afforded by them necessarily be obtained by using
replacement components rated for higher voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in the parts list of Service manual.

Electrical components having such features are identified
by shading on the schematics and by (
in Service manual.

does not have the same safety characteristics as the
recommended replacement part shown in the parts list of
Ser vice manual may cause s hoc k, fir e, or ot her haz ar ds.

4.

Use isolation transformer when hot chassis.

The chassis and any sub-chassis contained in s ome products
are con nec ted to one side of the AC power line. An is olati on
transformer of adequate capacity should be inserted between
the product and the AC power supply point while performing
any service on s ome products when the HOT chassis is
exposed.

5.

Don't short between the LIVE side ground and ISOLATED
(NEUTRAL) side ground or EARTH side ground when
repairing.

Some model's power circuit is partly different in the GND. The
differenc e of the GND is shown by the LIVE : () side GND,
the ISOLATED(NEUTRAL) : () side GND and EARTH : ()
side GND. Don't short between the LIVE side GND and
ISOLATED(NEUTRAL) side GND or EARTH side GND and
never measure with a measuring apparatus (oscilloscope etc.)
the LIVE side GND and ISOLATED(NEUTRAL) side GND or
EARTH side GND at the same time.
If above note will not be kept, a fus e or any parts will be broken.

6. If any repair has been made to the chassis, it is recommended
that the B1 setting should be checked or adjusted (See
ADJUSTMENT OF B1 POWER SUPPLY).

7. The high voltage applied to the picture tube must conform with
that specified in Servic e manual. Excessive high voltage can
cause an increase in X-Ray emission, arcing and possible
component damage, therefore operation under excessive high
voltage conditions should be kept to a minimum, or should be
prevented. If s evere arcing occurs, remove the AC power
immediately and determine the cause by visual inspection
(incorrect installation, cracked or melted high voltage harness,
poor soldering, etc.). To maintain the proper minimum level of
soft X-Ray emission, components in the high voltage circuitry
including the picture tube must be the exact replacements or
alternatives approved by the manufacturer of the complete
product.

8. Do not check high voltage by dr awing an arc. Use a high
voltage meter or a high voltage probe with a VTVM. Discharge
the picture tube before attempting meter c onnection, by
connecting a clip lead to the ground frame and connecting the
other end of the lead through a 10kΩ 2W resistor to the anode
button.

9. When service is required, observe the original lead dress.
Extra precaution should be given to assure correct lead dress
in the high voltage circuit area. W here a short circuit has
occurred, those c omponents that indicate evidence of
overheating should be replaced. Always use the
manufacturer's replacement components.

The use of a substitute replacement which

Isolation Check

(Safety for Electrical Shock Hazard)

After re-assembling the product, always perform an isolation
check on the expos ed metal parts of the cabinet (antenna
terminals, video/audio input and output terminals, Contr ol
knobs, metal cabinet, screwheads, earphone jack, control
shafts, etc.) to be sure the product is safe to operate without
danger of electrical shock.

(1)

Dielectric Strength Test

The isolation between the AC primary circuit and all metal parts
exposed to the user, particularly any exposed metal part having
a return path to the chassis should withstand a voltage of
1100V AC (r.m.s.) for a period of one second.

(. . . . W ithstand a voltage of 1100V AC (r.m.s.) to an appliance

rated up to 120V, and 3000V AC (r.m.s.) to an appliance rated
200V or more, for a period of one second.)
This method of test requires a test equipment not gener ally
fou nd in t he service trade.

(2)

Leakage Current Check

Plug the AC line cord directly into the AC outlet (do not use a
line isolation transformer during this check.). Using a "Leakage
Current Tester", measure the leakage c urrent from each
exposed metal part of the cabinet, particularly any exposed
metal part having a return path to the chassis, to a known good
earth gr ound (water pipe, etc.) . Any leakage current must not
exceed 0.5mA AC (r.m.s.).
However, in tropic al area, this must not exc eed 0.2mA AC
(r.m.s.).

Alternate Check M ethod

zzzz

Plug the AC line cord directly into the AC outlet (do not use a
line isolation transf ormer during this check.). Use an AC
voltmeter having 1000 ohms per volt or more sensitivity in the
following manner. Connect a 1500Ω 10W resistor paralleled

by a 0.15μF AC-type capacitor between an exposed metal
part and a known good earth ground (water pipe, etc.).
Measure the AC voltage across the resistor with the AC
voltmeter. Move the resistor connection to each exposed metal
part, particularly any exposed metal part having a return path to
the chassis, and measure the AC voltage across the resistor.
Now, reverse the plug in the AC outlet and repeat each
measurement. Any voltage measured must not exc eed 0.75V
AC (r.m.s.). This corresponds to 0.5mA AC (r.m.s.).
However, in tropic al area, this must not exceed 0.3V AC
(r.m.s.). This corresponds to 0.2mA AC (r.m.s.).

ADJUSTMENT OF PURITY / CONVERGENCE

PURITY ADJUSTMENT

1. Demagnetize CRT with the demagnetizer.

2. Loosen the retainer screw of the deflection yoke.

3. Remove the wedges.

4. Input a green raster signal from the signal generator, and turn
the screen to gr een raster.

5. Move the deflection yoke backward.

6. Bring the long lug of the purity magnets on the short lug and
position them horizontally. (Fig.2)

7. Adjust the gap between two lugs so that the GREEN RASTER
will come into the center of the screen. (Fig.3)

8. Move the deflection yoke forward, and fix the position of the
deflection yoke s o that the whole screen will become green.

9. Ins ert the wedge to the top side of the deflection yoke so that it
will not move.

HOW TO CHECK THE HIGH VOLTAGE HOLD DOWN CIRCUIT

1. HIGH VOLTAGE HOLD DOWN CIRCUIT

After repairing the high voltage hold down circuit shown in Fig. 1.
This circuit shall be checked to operate correctly.

2. CHECKING OF THE HIGH VOLTAGE HOLD DOWN CIRCUIT

(1) Turn the POWER SW ON.

(2) As shown in Fig. 1, set the resistor (between X connector 1 & 3 ).

(3) Make sure that the screen picture dis appears.

(4) Temporarily unplug the power cord.

(5) Remove the resistor (between X connector 1 & 3 ).

(6) Again plug the power c ord, make sure that the normal picture is displayed on the scr een.

SELF CHECK FUNCTIONS

1. Outline

This model has self check functions given below. W hen a malfunction has been detected, the POWER is turned off and the LED flashes to

inform of the failure . The malfunction is detected by the signal input state of the control line connected to the microcomputer.

2. Self check items

Check item Details of detection Method of detection State of malfunction

C-13310
C-13311

CRT NECK protector

Also detected if the
power supply line output
from the HVT (High
voltage Transf ormer) has
shorted with the ground.

3. Self check indicating function

The self-check function begins detection about 5 seconds after
power is supplied.
In the event a malfunction is detected, the power is cut off
immediately.
At this time, the ON-TIMER LED flashes to inform of the
malfunction.

[ON-TIMER LED indication]

The ON-T IMER LED flashes at 0.5 s econds intervals.

When th e vertical circuit S­correction capacitor C 427
is shorted, detect the
potential drop of the C427,
and prevent the burn
damage to the CRT NECK.

(Grounding of shorting of
the power supply output
from the HVT to the vertic al
circuit, and the small signal
power supply is also
detected.)

The microcomputer detects at

1 second intervals.

If NG is detected for more than

1 ms, a malfunction is interpreted.
