SAFETY PRECAUTIONS
1. The design of this product cont ains 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 identic al 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 injur y or property damage resulting
theref rom.
3. Many electric al and mechanical parts in the products have
special safety-related characteristics. These characteristics are
often not evident from visual inspection nor c an 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 s ame 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
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(NEUT RAL)
side GND or EARTH side GND and never measure with a
measuring apparatus (oscillosc ope 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 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 incr ease 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 det ermine the caus e by visual inspection
(incorrect installation, cr acked 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 manuf acturer 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, obser ve 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 occurr ed,
those components that indicate evidenc e of overheating should
be replaced. Always us e the manufactur er's replacement
components.
9. Isolation Check
(Safety for Electrical Shock Hazard)
After re-assembling the product, always perf orm an isolation
check on the exposed metal parts of the cabinet (antenna
terminals, video/audio input and output terminals, Control knobs,
metal c abinet, screwheads, earphone jack, c ontrol shafts, etc.)
to be sure the product is safe to operate without danger of
electr ic al sh oc k.
(1) Dielectr ic Strength Test
The isolation between the AC primary circuit and all metal parts
exposed to the user, particularly any expos ed 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 applianc e
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 found
in the s ervice trade.
(2) Leakage Current Check
Plug the AC line cord directly into the AC outlet (do not use a line
isolation transformer dur ing this check.). Using a " Leakage
Current T ester", 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 c urrent must not exceed
0.5mA AC (r.m.s.).
However, in tr opical 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 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 expos ed 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 meas ured
must not exceed 0.75V AC (r.m.s.). This corresponds to 0.5mA
AC (r.m.s.).
However, in tr opical area, this must not exc eed 0.3V AC (r.m.s.).
This corresponds to 0.2mA AC (r.m.s.).
