SAFETY

PRECAUTIONS

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

manufactur-

er.

Replacement

parts

must

be

identical

to

those

used

in

the

original

circuits.

Service

should

be

performed

by

qualified

per-

sonnel

only.

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

manufac-

turer

of

responsibility

for

personal

injury

or

property

damage

resulting

therefrom.

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

replace-

ment

components

rated

for

higher

voltage,

wattage,

etc.

Re-

placement

parts

which

have

these

special

safety

characteris-

tics

are

identified

in

the

parts

list

of

Service

manual.

Electri-

cal

components

having

such

features

are

identified

by

shading

on

the

schematics

and

by

(

4\)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

Ser-

vice

manual

many

create

shock,

fire,

or

other

hazards.

Don’t

short

between

the

LIVE

side

ground

and

NEU-

TRAL

side

grounding

or

EARTH

side

ground

when

re-

pairing.

Some

model’s

power

Circuit

is

partly

different

in

the

GND.

The

difference

of

the

GND

is

shown

by

the

LIVE

(1)

side

GND,

the

NEUTRAL(

»-)

side

GND

and

EARTH

(

®)

side

GND.

Don’t

short

between

the

LIVE

side

GND

and

NEUTRAL

side

GND

or

EARTH

side

GND

and

never

measure

with

a

mea-

suring

apparatus

(oscilloscope

etc.)

the

LIVE

side

GND

and

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.

lf

any

repair

has

been

made

to

the

chassis,

it

is

recommended

that

the

B1

setting

should

be

checked

or

adjusted

(See

AD-

JUSTMENT

OF

B,

POWER

SUPPLY).

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

im-

mediately

and

determine

the

cause

by

visual

inspection

(incor-

rect

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

in-

cluding

the

picture

tube

must

be

the

exact

replacements

or

al-

ternatives

approvided

by

the

manufacturer

of

the

complete

product.

Do

not

check

high

voltage

by

drawing

an

arc.

Use

a

high

volt-

age

meter

or

a

high

voltage

probe

with

a

VTVM.

Discharge

the

picture

tube

before

attempting

meter

connection,

by

con-

necting

a

clip

lead

to

the

ground

frame

and

connecting

the

other

end

of

the

lead

through

a

10kQ

2W

resistor

to

the

an-

ode

button.

When

service

is

required,

observe

the

original

lead

dress.

Ex-

tra

precaution

should

be

given

to

assure

correct

lead

dress

in

the

high

voltage

circuit

area.

Where

a

short

circuit

has

oc-

curred,

those

components

that

indicate

evidence

of

overheat-

ing

should

be

replaced.

Always

use

the

manufacturer's

re-

placement

components.

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

ter-

minals,

video/audio

input

and

output

terminals,

Control

knobs,

metal

cabinet,

screwheads,

earphone

jack,

control

shafts,

etc.)

to

be

sure

the

product

is

safe

to

operate

without

danger

of

electrical

shock.

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

appli-

ance

rated

up

to

120V,

and

3000V

AC

(r.m.s.)

to

an

appli-

ance

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.

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

ex-

posed

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.).

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

volt-

meter

having

1,000

ohms

per

volt

or

more

sensitivity

in

the

following

manner.

Connect

a

1,5002

10W

resistor

paralleled

by

a

0.15pF

AC-type

capacitor

between

an

exposed

metal

part

and

a

known

good

earth

ground

(water

pipe,

etc.).

Mea-

sure

the

AC

voltage

across

the

resistor

with

the

AC

voltmeter.

Move

the

resistor

connection

to

each

exposed

metal

part,

par-

ticularly

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

mea-

surement,

Any

voltage

measured

must

not

exceed

0.35V

AC

(r.m.s.).

This

corresponds

to

0.5MA
