NOTE ON USING CIRCUIT DIAGRAMS

1. SAFETY

The components identified by the symbol and shading are

critical for safety. For continued safety replace safety critical

components only with manufactures recommended parts.

2. SPECIFIED VOLTAGE AND WAVEFORM VALUES

The voltage and waveform values have been measured under the

following conditions.

(1) Input signal : Colour bar signal

(2)

Setting positions of each knob/button and variable resistor

:Original setting position when

shipped

(3) Internal resistance of tester : DC 20kØ/V

(4) Oscilloscope sweeping time : H ⇒20µS/div

:V ⇒5mS/div

:Others ⇒Sweeping time is

specified.

(5) Voltage values : All DC voltage values

9Since the voltage values of signal circuit vary to some extent ac-

cording to adjustments, use them as reference values.

3. INDICATION OF PARTS SYMBOL [EXAMPLE]

•In the PW board : R1209 →R209

4. INDICATIONS ON THE CIRCUIT DIAGRAM

(1) Resistors

•Resistance value

No unit : [Ø]

k:[kØ]

M:[MØ]

•Rated allowable power

No indication : 1/16 [W]

Others : As specified

•Type

No indication : Carbon resistor

OMR : Oxide metal film resistor

MFR : Metal film resistor

MPR : Metal plate resistor

UNFR : Non-Flammable resistor

FR : Fusible resistor

9Composition resistor 1/2 [W] is specified as 1/2S or Comp.

(2) Capacitors

•Capacitance value

1 or higher : [pF]

less than 1 : [µF]

•Withstand voltage

No indication : DC50[V]

AC indicated : AC withstand voltage [V]

Others : DC withstand voltage [V]

9 Electrolytic Capacitors

47/50[Example] : Capacitance value [µF]/withstand voltage[V]

•Type

(3) Coils

No unit : [µH]

Others : As specified

(4) Power Supply

:B1

:B2(12V)

:9V

:5V

9Respective voltage values are indicated

(5) Test point

:Test point

: Only test point display

(6) Connecting method

: Connector

:Wrapping or soldering

:Receptacle

(7) Ground symbol

:LIVE side ground

:ISOLATED(NEUTRAL) side ground

:EARTH ground

:DIGITAL ground

5. NOTE FOR REPAIRING SERVICE

This model’s power circuit is partly different in the GND. The difference

of the GND is shown by the LIVE : ( ) side GND and the

ISOLATED(NEUTRAL) : ( ) side GND.Therefore, care must be taken

for the following points.

(1) Do not touch the LIVE side GND or the LIVE side GND and the

ISOLATED(NEUTRAL) side GND simultaneously. If the above cau-

tion is not respected, an electric shock may be caused. Therefore,

make sure that the power cord is surely removed from the recepta-

cle when, for example, the chassis is pulled out.

(2) Do not short between the LIVE side GND and ISOLATED(NEUTRAL)

side GND or never measure the LIVE side GND and

ISOLATED(NEUTRAL) side GND at the same time with a measur-

ing apparatus ( oscilloscope, etc.). If the above precaution is not

respected , a fuse or any parts will be broken.

•Since the circuit diagram is a standard one, the circuit and cir-

cuit constants may be subject to change for improvement with-

out any notice.

SAFETY PRECAUTIONS

1. The design of this product contains special hardware, many circuits

and components specially for safety purposes. For continued pro-

tection, 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 manufactur-

er's warranty and will further relieve the manufacturer of responsi-

bility 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 (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 ISO-

LATED (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 dam-

age, 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 10kØ2W 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 com-

ponents 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.

(1) 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.

(2) 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 hav-

ing 1000 ohms per volt or more sensitivity in the following manner.

Connect a 1500Ø10W resistor paralleled by a 0.15µF AC-type ca-

pacitor between an exposed metal part and a known good earth

ground (water pipe, etc.). Measure the AC voltage across the resis-

tor with the AC voltmeter. Move the resistor connection to each ex-

posed metal part, particularly any exposed metal part having a re-

turn 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.).
