SAFETY

PRECAUTION

1.

The

of

this

product

contains

special

hardware,

8.

ISOLATION

CHECK

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.

.

Alterations

of

the

design

or

circuitry

of

receiver

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.

.

Many

electrical

and

mechanical

parts

in

television

sets

have

special

safety-related

characteristics.

These

char-

acteristics

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

recom-

mended

replacement

part

shown

in

the

parts

list

in

Service

manual

may

create

shock,

fire,

or

other

hazards.

.

If

any

repair

has

been

made

to

the

chassis,

it is

recom-

mended

that

the

B,

setting

should

be

checked

or

ad-

justed.

(See

ADJUSTMENT

OF

POWER

SUPPLY).

.

The

high

voltage

applied

to

the

picture

tube

must

con-

form

with

that

specified

in

Service

manual.

Excessive

high

voltage

can

cause

an

increase

in

X-Ray

emission,

arcing

and

possible

component

damage,

therefore

opera-

tion

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

approvided

by

the

manu-

facturer

of

the

complete

product.

.

Do

not

check

high

voltage

by

drawing

an

arc.

Use

a

high

voltage

meter

or

a

high

voltage

probe

with

a

VT

VM.

Dis-

charge

the

picture

tube

before

attempting

meter

connec-

tion,

by

connecting

a

clip

Jead

to

the

ground

frame

and

connecting

the

other

end

of

the

lead

through

a

10kQ2

2W

resistor

to

the

anode

button.

.

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.

(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,

channel

selector

knobs,

metal

cabinet,

screwheads,

earphone

jack,

etc.)

to

be

the

product

is

to

operate

without

danger

of

electrical

shock.

having

a

CHECK

Plug

the

directly

into

the

AC

outlet

(do

not

use

transformer

during

this

check.)

Using

a

‘Leakage

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

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

transformer

during

this

check.).

Use

an

AC

voltmeter

having

1,000

ohms

per

volt

or

more

sensitivity

in

the

following

manner.

Connect

a

150022

10W

resistor

paralleled

by

a

0.15uF

AC-type:

capacitor

between

an

exposed

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

measured

must

not

exceed

0.35V
