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) 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 difference 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 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.
(5) 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).
(6) 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.
(7) 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 10kΩ
2W resistor to the anode button.
(8) 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.
(9) 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 3000V AC (r.m.s.) for a period of one second.
(. . . . Withstand 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 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.).
Alternative 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 1000 ohms per 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.).

3.1 DISASSEMBLY PROCEDURE
3.1.1 REMOVING THE REAR COVER
•Unplug the power cord.
(1) Remove the 16 screws [A] as shown in Fig.1.
(2) Withdraw the REAR COVER toward you.
CAUTION:
When reinstalling the rear cover, carefully push it inward
after inserting the MAIN PWB into the REAR COVER groove.
3.1.2 REMOVING THE CHASSIS (CHASSIS BASE AND
CONTROL BASE)
•Remove the REAR COVER.
(1) Slightly raise the both sides of the CHASSIS by hand
and remove the 2 claws [B] under the CHASSIS from
the front cabinet as shown in Fig.1.
(2) Withdraw the CHASSIS backward.
(If necessary, take off the wire clamp, connectors etc.)
NOTE:
When conducting a check with power supplied, be sure to
confirm that the CRT earth wire is connected to the CRT
SOCKET PWB and the MAIN PWB.
3.1.3 REMOVING THE AV TERMINAL BOARD
•Remove the REAR COVER.
(1) Remove the 4 screws [C] as shown in Fig.1.
(2) When you pull out the AV TERMINAL BOARD in the
direction of arrow [D] as shown in Fig.1, it can be
removed.
3.1.4 REMOVING THE CONTROL BASE
•Remove the REAR COVER.
•Remove the CHASSIS.
(1) While pushing down the 2 claws [E] as shown in Fig.
2 and pull out the CONTROL BASE in the direction of
arrow [F] as shown in Fig. 2, the control base can be
removed.
(If necessary, take off the wire, connectors etc.)
3.1.5 REMOVING THE SPEAKER
•Remove the REAR COVER.
(1) Remove the 2 screws [G] as shown in Fig.1.
(2) Withdraw the SPEAKER backward.
(3) Follow the same steps when removing the other hand
SPEAKER.
3.1.6 CHECKING THE MAIN PW BOARD
•To check the back side of the MAIN PWB.
(1) Pull out the CHASSIS and CONTROL BASE. (Refer to
the procedure described in REMOVING THE
CHASSIS)
(2) Put the CHASSIS in upright position with the MAIN
PWB's solderside faced to the right. The FBT must be
positioned on top. (Viewed from the rear)
(3) Put the CONTROL PWBs in an appropriate position,
taking care not giving tension to the ribbon cables that
connect to the MAIN PWB.
CAUTIONS:
•Use insulating materials, if necessary, to avoid possible
electrical contacts between PWBs and expose terminals,
etc.
•Before turning on power, make sure that the CRT earth
wire and other connectors are properly connected.
•When repairing, connect the DEG. COIL to the DEG.
connector on the MAIN PWB.
3.1.7 WIRE CLAMPING AND CABLE TYING
(1) Be sure to clamp the wire.
(2) Never remove the cable tie used for tying the wires
together.
Should it be inadvertently removed, be sure to tie the
wires with a new cable tie.

3.2 REPLACEMENT OF MEMORY IC
3.2.1 MEMORY IC
This TV uses the following memory IC.
Memory IC: IC702 on MAIN PWB
The memory IC memorizes data for correctly operating the
video and deflection circuits. When replacing the memory
IC, be sure to use the same type IC written with the initial
values of data. In other words, use the specific IC listed in
