are

positioned

in

such

a

way

as

to

avoid

possibility

of

adjacent

component

shorts.

This

is

especially

important

on

those

chassis

which

are

transported

to

and

from

the

repair

shop.

2.

Never

release

point

and

on

all

exposed

metallic

parts

of

the

cabinet,

(the

are

equipped

with

an

integral

implosion

protection

system,

but

care.should

be

taken

to

avoid

damage

during

SUBJECT:

X-RADIATiON

1.

Be

sure

procedures

and

instructions

to

all

service

personnel

cover

the

subject

of

X-radiation.

The

orily

potential

source

of

X-rays

in

current

TV

receivers

is

the

picture

tube.

However,

this

tube

does

not

emit

X-rays

when

the

H.V.

is

at

the

factory

specified

level.

It

is

only

when

the

H.V.

is

excessive

that

X-radiation

may

be

generated.

Refer

to

the

X-ray

Precaution

Label

which

is

located

inside

each

television

receiver

for

the

correct

high

voltage.

The

proper

value

is

also

given

in

the

applicable

service

manual.

Operation

at

higher

I

voltages

may

cause

a

failure

of

the

picture

tube

or

high

voltag!l

supply

and,

under

certain

circumstances,

may

produce

radiation

in

excess

of

desirable

levels.

2.

Only

Zenith

specified

CRT

anode

connectors

must

be

used.

The

degaussing

shield

also

serves

as

an

X-ray

shield

in

color

sets,

do

not

defeat

its

purpose.

.

3.

It

is

essential

that

the

serviceman

has

available

an

accurate

and

reliable

high

voltage

meter.

The

calibration

of

the

meter

should

be

checked

periodically

against

a

reference

standard,

such

as

the

one

available

at

your

distributor.

4.

When

the

high

voltage

circuitry

is

operating

properly

there

is

no

possibility

of

an

X-radiation

problem.

Every

time

a

color

chessis

is

serviced,

the

brightness

should

be

run

up

and

down

while

monitoring

the

high

voltage

with

a

meter

to

be

certlin that

the

high

voltage

does

not

exceed

the

specified

value

and

that it

is

regulating

correctly.

We

suggest

that

you

and

your

service

organization

review

test

procedures

so

that

voltage

regulation

is

always

checked

as

a

standard

servicing

procedure,

and

that

the

high

voltage

reading

be

recorded

on

each

customer's

invorce.

5.

When

trouble

shooting

and

making

test

measurements

in

a

receiver

with

a

problem

of

excessive

high

voltage,

avoid

being

unnecessarily

close

to

the

picture

tube

and

the

high

voltage

compartment.

Do

not

operate

the

chassis

longer

than

is

necessary

to

locate

the

cause

of

excessive

voltage.

6.

Color

transistor

sets

manufactured

after

June,

1973

("E"

Line

and

later),

use

new

type

picture

tubes

specifically

designed

to

withstand

higher

operating

voltages

without

causing

excessive

X-radiation.

It

is

strongly

recommended

that

the

C.R.T.

shop

fixture

be

equipped

with

the

new

type

tube.

Addition

of

a

permanently

connected

H.V.

meter

to

the

H.V.

anode

of

the

shop

C.R.T.

fixture

is

advisable.

The

C.R.T.'s

in

these

sets

should

never

be

replaced

with

any

other

tube

types

as

that

may

result

in

exc_ive

X-radiation

and

possible

violation

of

the

law.

7.

Starting

with

late

production

"E"

line

color

sets,

a

special

four

lead

damper

capacitor

was

used.

Its

feature,

the

interlocking

four

leads,

should

not

be

defeated.

However,

each

time

one

of

these

sets

is

serviced,

for

whatever

reason,

the

part

number

of

the

capacitor

should

be

examined.

If

it

is

the

22-7233

type

(used

in

"E"

and

"F"

model

lines

only),

that

capacitor

must

be

replaced

with

an

improved

recommended

type

(22-7504.()1).

Please

refer

to

Zenith

Tech

Topics

(Issue

details.

Your

distributor

will

answer

any

questions,

or

you

may

write

to

Zenith

for

further

details.

DISASSEMBLY PROCEDURES

Disassembly of the

13"

receivers is simplified by using a

nominal amount

of

screws on the cabinet assembly and on

the frame assembly.

To remove the cabinet back proceed

as

follows:

1.

Remove two screws from top edge of cabinet back.

2.

Remove one screw located next to antenna terminal.

3.

Remove three screws from bottom edge of cabinet

back.

One screw located next

to

focus control fastens the Video

Module Access Door. This screw need

not

be

removed

when the cabinet back is being removed.

When removing individual boards, proceed with caution

while you disengage seated boards from the modular

frame assembly. Do

not

use an excessive force.

To remove

M10

board,

first

remove the key-lock holding ft'le

board down in place. To remove key-lock,

twist

it

90° and

pull

it

up. Removal of M10 board (if rest

of

module

assembly is in place) also requires unscrewing center

screw from bottom edge

of

cabinet. Disengaging edge con-

nectors from the boards occasionally requires removal

of

small holder tabs inserted

into

edge connector holes.

Removal

of

M5

board is more

difficult

on 13" receivers than

on previous models. New

M5

holding frame was designed

to

prevent shipment damage. Two tabs are restricting

disengagement of the board. It is advisable

to

remove the

M5

board from its frame when you service

it

the

first

time,

then you can break the tabs

off

for

easier removal in the

future.

RF INTERFERENCE MODIFICATION

PROCEDURE

Undercertain conditions a nearby television receiver tuned

to

channel 2 may be affected by the normal operation

of

the

DC

13

color monitor. The coridition can

be

eliminated

by the installation

of

a capacitor on one

of

the modules in

the color monitor. Detailed instructions are as follows:

1.

The capacitor to use is a

20

pf

capacitor part number

22-7639-15

or

-15C.

2.

Install the capacitor as indicated in figure

12.

NOTE: The capacitor should

be

connected in

parallel

to

resistor

R1203

(R1203

may

b.e

labeled

R203

on some modules). However,

easy access is available

to

the component

side and the fix requires only removal

of

the

cabinet back.
