Proper

service

and

repair

is

important

to

the

sate,

reliable

operation

of

ail

PHILIPS

Consumer

Electronics

Company**

Equipment.

The

service

procedures

recommended

by

PHILIPS

and

described

in

this

service

manual

are

effective

methods

of

performing

service

operations.

Some

of

these

service

operations

require

the

use

of

tools

specially

designed

for

the

purpose.

The

special

tools

should

be

used

when

and

as

recommended.

It

is

important

to

note

that

this

manual

contains

various

CAUTIONS

and

NOTICES

which

should

be

carefully

read

in

order

to

minimize

the

risk

of

personal

injury

to

service

personnel.

The

possibility

exists

that

improper

service

methods

may

damage

the

equipment.

It

is

also

important

to

understand

that

these

CAUTIONS

and

NOTICES

ARE NOT

EXHAUSTIVE.

PHILIPS

could

not

possibly

know,

evaluate

and

advise

the

service

trade

of

all

conceivable

ways

in

which

service

might

be

done

or

of

the

possible

hazardous

consequences

of

each

way.

Consequently,

PHILIPS

has

not

undertaken

any

such

broad

evaluation.

Accordingly,

a

servicer

who

uses

a

service

procedure

or

tool

which

is

not

recommended

by

PHILIPS

must

first

satisfy

himself

thoroughly

that

neither

his

safety

nor

the

safe

operation

of

the

equipment

will

be

jeopardized

by

the

service

method

selected.

**

Hereatter

throughout

this

manual,

PHILIPS

Consumer

Electronics

Company

will

be

referred

to

as

PHILIPS.

(STFC)

Your

provides

a

self-test

feature

that

allows

you

to

check

whether

your

is

functioning

properly.

If

your

monitor

run

the

performing

the

following

steps:

1.

Turn

2.

Unplug

the

Use

Discharge

until

the

meter

reading

is

0

V

(after

approximately

30

seconds).

esp

&

All

ICs

and

many

other

semiconductors

are

sensitive

to

electrostatic

discharges

(ESD).

Careless

handling

during

repair

can

drastically

shorten

their

life.

Make

sure

that

during

repair

you

are

connected

by

a

pulse

band

with

resistance

to

the

same

potential

as

the

ground

of

the

unit.

Keep

components

and

tools

also

at

this

same

potential.

When

repairing

a

unit,

atways

connect

it

to

the

AC

Power

voltage

via

an

isolating

transformer.

Be

careful

when

taking

measurements

in

the

high-voltage

section

and

on

the

picture

tube

panel.

It

is

recommended

that

saferty

goggies

be

worn

when

replacing

the

picture

tube.

When

making

adjustments,use

piastic

rather

than

metal

tools.

This

will

prevent

any

short-circuit

or

the

danger

of

a

circuit

becoming

unstable.

Never

replace

modules

or

other

components

while

the

unit

is

switched

on.

Together

with

the

defleciton

unit,

the

picture

tube

is

used

as

an

integrated

unit.

Adjustment

of

this unit

during

repair

is

not

recommended.

After

repair,

the

wiring

should

be

fastened

in

place

with

the

cable

All

must

pass
