IMPORTANT

SAFETY

NOTICE

There

are

special

components

used

in

Panasonic

Monitor

sets

which

are

important

for

safety.

These

parts

are

shaded

on

the

schematic

diagram.

|t is

essential

that

these

critical

parts

should

be

replaced

with

manufacturer's

specified

parts

to

prevent

X-RADIATION,

shock,

fire,

or

other

hazards.

Do

not

modify

the

original

design

without

permission

of

PANASONIC

BROADCAST

&

TELEVISION

SYSTEMS

COMPANY.

Safety

Precaution

GENERAL

GUIDELINES

1.

It

is

advisable

to

insert

an

isolation

transformer

in

the

AC

supply

before

servicing

a

hot

chassis.

2.

When

servicing,

observe

the

original

lead

dress,

especially

the

lead

dress

in

the

high

voltage

circuits.

If

a

short

circuit

is

found,

replace

all

parts

which

have

been

overheated

or

damaged

by

the

short

circuit.

3.

After

servicing,

see

to

it

that

all

the

protective

devices

such

as

insulation

barriers,

insulation

papers,

shields,

and

isolation

R-C

combinations,

are

properly

installed.

4.

Before

turning

the

monitor

on,

measure

the

resistance

between

130V

line

and

hot

side

ground

(TP92),

between

B+

line

and

cold

side

ground

(TPA5).

Connect

the

O

side

of

an

ohmmeter

to

the

B+

lines,

and

the

@

side

to

ground

(ТРА5).

Each

line

should

have

more

resistance

than

specified,

as

follows:

150У

(ТР9Г

11.1V

(TPA6)

5000

17.3V

(TPA7)

24.5V

(TPA8)

186V

(TPA10)

5000

100kQ

5.

When

the

monitor

is

not

used

for

a

long

period

of

time,

unplug

the

power

cord

from

the

AC

outlet.

6.

Potentials,

as

high

as

24.5kV+1.5kV

are

present

when

this

monitor

is

in

operation.

Operation

of

the

monitor

without

the

rear

cover

involves.

the

danger

of

a

shock

hazard

from

the

monitor

power

supply.

Servicing

should

not

be

attempted

by

anyone

who

is

not

thoroughly

familiar

with

the

precautions

necessary

when

working

on

high

voltage

equipment.

Always

discharge

the

anode

of

the

picture

tube

to

chassis

ground

before

handling

the

tube.

7.

After

servicing,

make

the

following

leakage

current

checks

to

prevent

the

customer

from

being

exposed

to

shock

hazards.

LEAKAGE

CURRENT

COLD

CHECK

1.

Unplug

the

AC

cord

and

connect

a

jumper

between

the

two

prongs

on

the

plug.

2.

Turn

on

the

monitor's

power

switch.

3.

Measure

the

resistance

value,

with

an

ohmmeter,

between

the

jumpered

AC

plug

and

each

exposed

metallic

cabinet

part

on

the

monitor,

such

as

screwheads,

connectors,

control

shafts,

etc.

When

the

exposed

metallic

part

has

a

return

path

to

the

chassis,

the

reading

should

be

more

than

1MQ.

When

the

exposed

metal

does

not

have

a

return

path

to

the

chassis,

the

reading

must

be

oo.

LEAKAGE

CURRENT

HOT

CHECK

(See

Fig.

1)

1.

Plug

the

AC

cord

directly

into

the

AC

outlet.

Do

not

use

an

isolation

transformer

for

this

check.

2.

Connect

a

1.5

kQ,

10

watt

resistor,

in

parallel

with

a

0.15

uF

capacitor,

between

each

exposed

metallic

part

on

the

set

and

a

good

earth

ground

such

as

a

water

pipe,

as

shown

in

Fig.

1.

3.

Use

a

high

impedance

AC

voltage

meter

to

measure

the

potential

across

the

resistor.

4.

Check

each

exposed

metallic

part,

and

measure

the

voltage

at

each

point.

5.

The

potential

at

any

point

should

not

exceed

0.75

volts

RMS.

A

leakage

current

tester

(Simpson

Model

229

or

equivalent)

may

be

used

to

make

the

hot

checks,

leakage

current

must

not

exceed

500uA.

In

case

a

measurement

is

outside

of

the

limits

specified,

there

is

a

possibility

of

a

shock

hazard,

and

the

monitor

should

be

repaired

and

rechecked

before

it

is

returned

to

the

customer.

Circuit

Explanation

HORIZONTAL

OSCILATOR

DISABLE

CIRCUIT

To

monitor

the

high

voltage,

the

positive

DC

voltage

from

the

cathode

of

D531

is

applied

through

zener

diode

D571

and

D572

and

divided

by

R532

and

R533

to

49

of

IC301,

which

is

the

input

terminal

of

the

X-Ray

Protection

Circuit.

Under

normal

conditions,

this

voltage

is

insufficient

to

activate

the

X-Ray

Protection

Circuit.

If

the

high

voltage

increase

over

the

specified

voltage,

the

voltage

at

the

49

of

IC301

increases

and

causes

the

X-Ray

Protection

Circuit

to

activate.

Then

it

causes

the

horizontal

oscillator

frequency

to

increase,

loss

of

holizontal

synchronization

and

lowering

of

the

high

voltage.

In

the

process

described

above,

the

voltage

at

the

49

of

IC301

is

compared

with

the

voltage

at

51

of

IC301

which

is

basically

a

constant

voltage

fed

from

the

zener

diode

D532,

divided

by

R539

and

R535.

If

excessive

beam

current

is

drawn,

the

lowered

voltage

is

fed

to

51

of

(301

through

zener

diode

D570

and

R534

to

aid

operation

of

the

X-Radiation

Protection

Circuit.
