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 therecommended 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

(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 sideGND 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 ADJUSTMENT

OF B1 POWER SUPPLY).

(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 10k 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. 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 isolatio

check on the exposed metal parts of the cabinet (antenn

terminals, video/audio input and output terminals, Control knob

metal cabinet, screw heads, earphone jack, control shafts, etc.)

be sure the product is safe to operate without danger of electric

shock.

a) Dielectric Strength Test

The isolation between the AC primary circuit and all metal par

exposed to the user, particularly any exposed metal part having

return path to the chassis should withstand a voltage of 3000V A

(r.m.s.) for a period of one second. (. . . . Withstand a voltage

1100V AC (r.m.s.) to an appliance rated up to 120V, and 3000

AC (r.m.s.) to an appliance rated 200V or more, for a period of on

second.)

This method of test requires a test equipment not generally foun

in the service trade.

b) Leakage Current Check

Plug the AC line cord directly into the AC outlet (do not use a lin

isolation transformer during this check.). Using a "Leakag

Current Tester", measure the leakage current from each exposemetal part of the cabinet, particularly any exposed metal pa

having a return path to the chassis, to a known good earth grou

(water pipe, etc.). Any leakage current must not exceed 0.5mA A

(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

line isolation transformer during this check.). Use an A

voltmeter having 1000 per volt or more sensitivity in th

following manner. Connect a 1500 10W resistor paralleled b

a 0.15F AC-type capacitor between an exposed metal part an

a known good earth ground (water pipe, etc.). Measure the A

voltage across the resistor with the AC voltmeter. Move th

resistor connection to each exposed metal part, particularly a

exposed metal part having a return path to the chassis, anmeasure the AC voltage across the resistor. Now, reverse th

plug in the AC outlet and repeat each measurement. An

voltage measured must not exceed 0.75V AC (r.m.s.). Th

corresponds to 0.5mA AC (r.m.s.).

However, in tropical area, this must not exceed 0.3V A

(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 sh

be checked to operate correctly.See item "How to check the hig

voltage hold down circuit".
