SECTION 1
PRECAUTION
1.1 SAFETY PRECAUTIONS
(1) The design of this product 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 manufacturer.
Replacement parts must be identical to those used in the original
circuits. Service should be performed by qualified personnel only.
(2) Alterations of the design or circuitry of the products should not be
made. Any design alterations 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 electrical and mechanical 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 ( ) on the
parts list in Service manual. The use of a substitute replacement
which does not have the same safety characteristics as the
recommended replacement part shown in the parts list of Service
manual may cause shock, fire, or other hazards.
(4) Use isolation transformer when hot chassis.
The chassis and any sub-chassis contained in some products are
connected to one side of the AC power line. An isolation
transformer of adequate capacity should be inserted between the
product and the AC power supply point while performing any
service on some products when the HOT chassis is exposed.
(5) Don't short between the LIVE side ground and ISOLATED (NEU-
TRAL) side ground or EARTH side ground when repairing.
Some model's power circuit is partly different in the GND. The differ-
ence of the GND is shown by the LIVE : ( ) side GND, the ISOLAT-
ED (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 the LIVE side
GND and ISOLATED (NEUTRAL) side GND or EARTH side GND at
the same time with a measuring apparatus (oscilloscope etc.). If
above note will not be kept, a fuse 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 B1 POWER
SUPPLY check).
(7) The high voltage applied to the picture tube must conform with that
specified in Service 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 severe 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 drawing an arc. Use a high voltage
meter or a high voltage probe with a VTVM. Discharge the picture
tube before attempting meter connection, by connecting a clip lead
to the ground frame and connecting the other end of the lead
through a 10kΩ2W 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. Where a short circuit has occurred, those
components that indicate evidence of overheating should be
replaced. Always use the manufacturer's replacement
components.
(10) Isolation Check (Safety for Electrical Shock Hazard)
After re-assembling the product, always perform an isolation
check on the exposed metal parts of the cabinet (antenna
terminals, video/audio input and output terminals, Control knobs,
metal cabinet, screw heads, earphone jack, control shafts, etc.) to
be sure the product is safe to operate without danger of electrical
shock.
a) 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.
(. . . . Withstand a voltage of 1100V AC (r.m.s.) to an appliance rat-
ed 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 generally found in the service trade.
b) 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 current 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 ground
(water pipe, etc.). Any leakage current must not exceed 0.5mA AC
(r.m.s.).
However, in tropical area, this must not exceed 0.2mA AC (r.m.s.).
Alternate Check Method
Plug the AC line cord directly into the AC outlet (do not use a
line isolation transformer during this check.). Use an AC
voltmeter having 1000Ωper volt or more sensitivity in the
following manner. Connect a 1500Ω10W 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 exceed 0.75V AC (r.m.s.). This
corresponds to 0.5mA AC (r.m.s.).
However, in tropical area, this must not exceed 0.3V AC
(r.m.s.). This corresponds to 0.2mA AC (r.m.s.).
(11) High voltage hold down circuit check.
After repair of the high voltage hold down circuit, this circuit shall
be checked to operate correctly.See item "How to check the high
voltage hold down circuit".

3.2.9 REMOVING THE CRT
NOTE:
• Replacement of the CRT should be performed by 2 or more
persons.
• After removing the REAR COVER, CHASSIS etc.,
(1) Putting the CRT change table on soft cloth, the CRT
change table should also be covered with such soft cloth
(shown in Fig. 3).
(2) While keeping the surface of CRT down, mount the TV set
on the CRT change table balanced will as shown in Fig. 3.
(3) Remove 4 screws marked by arrows with a box type
screwdriver as shown in Fig. 4.
NOTE:
Since the cabinet will drop when screws have been
removed, be sure to support the cabinet with hands.
(4) After 4 screws have been removed, put the cabinet slowly
on cloth (At this time, be carefully so as not to damage the
front surface of the cabinet) shown in Fig. 5.

COATING OF SILICON GREASE FOR ELECTRICAL INSULATION ON THE CRT ANODE CAP SECTION.
Subsequent to replacement of the CRT and HV transformer or repair of the anode cap, etc. by dismounting them, be sure to coat
silicon grease for electrical insulation as shown in Fig.6.Wipe around the anode button with clean and dry cloth. (Fig.6)Coat silicon
grease on the section around the anode button. At this time, take care so that any silicon greases dose not sticks to the anode
button. (Fig.7)
Silicon grease product No. KS - 650N
Fig.6 Fig.7
CAUTION FOR DEGAUSSING WORKS
Whenever degaussing works are required due to
distorted images and colors caused by the replacement
of the CRT or other external magnetic forces, self-
degaussing (internal degaussing) should be carried out
without fail instead of degaussing the monitor from the
outside.
Because of the characteristics of the CRT used in this
monitor , the distorted images and colors may worsen if
degaussing the monitor from the outside has been
performed.
Even if external degaussing works have been carried out,
self-degaussing should be performed by turning the
power on the monitor.
When you want to perform self-degaussing of the monitor
whose power is already turned on, turn of f the power and
wait for about 10 minutes before turning the power on the
monitor again for self-degaussing.
