circuits and components especially for safety purposes. For
continued prot ection, no changes should be made to t

original design unless authorized in writing by th
e
manufacturer. Replacem ent parts m ust be identical to thos
e
used in the original circuits. Service should be performed b
y
qualified personnel only.
2. Alterations of the design or circuitry of the products shoul
d
not be made. Any design alterations or additions will void th
e
manufacturer’s warranty and will further relieve th
e
manufacturer of responsibility for personal injury or proper
ty
damage resulting therefrom.

(Safety for Electrical Shock Hazard)
After re-assem bling the product, always perform an isolati
on
check on the exposed metal parts of the cabinet (ant enn
a
term inals, video/ audio input and output terminals, Contro
l
knobs, metal cabinet, screw heads, earphone jack, contro
l
shafts, etc.) to be sure the product is safe to operate withou
t
danger of electrical shock.
10. The surface of the TV screen is coated with a thin film which
can easily be damaged. Be very careful with it when handl
e
the TV. Should the TV screen becom e soiled, wipe it with
a
soft dry cloth. Never rub it forcefully. Never use any cleane
r
or detergent on it.

special safety-related characteristics. These characteristi
cs
are oft en not evident from visual inspection nor can t
he
protection afforded by them necessarily be obtained by usin
g
replacem ent components rated for higher voltage, wattage
,
etc. Replacem ent parts which have these special safet
y
characteristics are identified in the parts list of Servic
e
manual. Electrical com ponents having such features ar
e
identified by shading on the schem atics and by (  )
on
the parts list in Service manual. The use of a substitut
e
replacem ent which does not have the sam e safet
y
characteristics as the recommended replacem ent par
t
shown in the parts list of Service manual may cause shock
,
fire, or other hazards
4. Don’t short between the LIVE side ground an
d
ISOLATED (NEUTRAL) side ground or EARTH sid
e
ground when repairing . Some model’s power circuit i
s
partly different in the GND. The difference of the GND i
s
shown by the LIVE: ( ) side GND, 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 neve
r
measure with a m easuring apparat us (oscilloscope etc.) t
he
LIVE side GND and ISOLATED (NEUTRAL) side GND o
r
EARTH side GND at the sam e tim e. If above note will not
be
kept, a fuse or any parts will be broken.
5. If any repair has been m ade to the chassis, it i
s
recomm ended that the B1 setting should be checked o
r
adjusted (See ADJUSTMENT OF B1 POW ER SUPPLY).
6. The high voltage applied to the picture tube must conform t
o
that specified in Service manual. Excessive high voltage c
an
cause an increase in X-Ray em ission, arcing and possibl
e
component dam age, therefore operation under excessiv
e
high voltage conditions should be kept to a minim um, o
r
should be prevented. If severe arcing occurs, rem ove the A
C
power immediately and determine the cause by visua
l
inspection (incorrect installation, cracked or m elt ed hig
h
voltage harness, poor soldering, etc.). To maintain the prope
r
minimum level of soft X-Ray emission, com ponents in th
e
high voltage circuitry including the picture tube must be t
he
exact replacem ents or alternatives approved by t
he
manufacturer of the complete product.

The isolation between the AC prim ary circuit and all meta
l
parts exposed to the user, particularly any exposed meta
l
part having a return path to the chassis should withstand
a
voltage of 3000V AC (r.m.s.) for a period of one second.
(…W ithstand a voltage of 1100V AC (r.m.s.) to an applianc
e
rated up to 120V, and 3000V AC (r.m.s.) to an applianc
e
rated 200V or more, for a period of one second.)
This method of test requires test equipm ent not generall
y
found in the service trade.
(2) Leakage Current Check
Plug the AC line cord directly int o the AC outlet (do not use
line isolation transform ers during this check). Using a
“Leakage Current Test er”, m easure the leakage current fro
m
each exposed metal part of the cabinet, particularly an
y
exposed m etal part having a return path t o the chassis, to
a
known good earth ground (water pipe, etc.). Any leakag
e
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 A
C
voltmeter having 1000 ohm s per volt or more sensitivity i
n
the following manner. Connect a 1500Ω 10W resisto
r
paralleled by a 0.15µF AC-type capacit or between a
n
exposed m etal part and a known good earth ground (wate
r
pipe, etc.). Measure the AC voltage across the resistor wit
h
the AC voltmeter. Move the resistor connection to eac
h
exposed metal part, particularly any exposed metal par
t
having a return path to the chassis, and m easure the A
C
voltage across the resistor. Now, reverse the plug in the A
C
outlet and repeat each m easurem ent. Any voltage measur
ed
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 0.2m A AC (r.m.s.)
