SERVICE

INSTRUCTIONS

NOTE:

All monitors are equipped with automatic degaussing

coils

(L701) which demagnetize the picture tube

every

time

the monitorIs turned

on

after

being

off

for a minimum

of

5 minutes. Should any part

of

the chassis

become magnetized

It

will be necessary

to

degauss the affected area with a manual degaussing coil. Move

the coil

slowly

around the

CRT

face area and all surrounding metal parts. Then slowly withdraw for adistance

of

6 feet before turning off.

Horizontal vs. Vertical:

Some models have the picture tube mounted vertically rather than horizontally. That

Is,

the picture tube Is

mounted in the frame such that the long dimension

of

the tube Is up and down. Examples

of

this include(but

are not

limited

to) Models

K4951,

K4952,

K4956,

K4956R, and

K4961

as

In

the pictures on the bottom

of

the

front cover. Other than the physical orlentatlon

of

the picture tube, there Is

no

electrical difference between

these models and their horizontal counterparts. The same circuits, the vertical circuits, produce and control

deflection along the short dimension

of

the tube In all models.

The same circuits, the horizontal circuits, produce and control deflection along the long dimension

of

the

tube

In

all models.,Therefore, wherever "vertical" appears in this manual

or

on the monitor,

it

refers to the short

dimension

of

the picture tube; wherever "horizontal" appears,

lt

refers tothe long dimension

of

the picture tube.

1.0

BLACK

LEVEL CONTROL ADJUSTMENT

This control has been set at the factory and should not need further at-

tention. However, when the game is connected 3 slight adj1Jstment

of

VR201

may

be

necessary to obtain the proper black level (the black

portion

of

the picture just extinguished).

2.0 VERTICAL SIZE (HEIGHT)

Location

of

this control is shown in Fig.

1.

This control must

be

adjust-

ed

slowly,

If

necessary, until the picture or test pattern attains the cor-

rect vertical proportions.

NOTE:

This adjustment interactswith thevertical dampingadjustment

described in the paragraph below. Umay

be

necessary to readjust the

vertical size after the vertical damping control has been adjusted.

3.0 VERTICAL DAMPING

Adjustment

of

this control is required only if the monitoris being used

with a game in which the top several raster lines are visible

on

the

screen. Adjust the vertical damping control for uniform spacing

of

the

top raster lines.

4.0 CIRCUIT PROTECTION

A 4.0A ptgtall fuse, mounted on the Main Board has been provided to

protect the Power Output Circuit.

5.0 FOCUS

Adjust the Focus control, located on the

HV

unit(T352), for maximum

over-all definition and fine picture detall.

6.0 HORIZONTAL

HOLD

CONTROL ADJUSTMENT, VR351

(See

Fig.

1a

or

1b)

A warm-up period

of

at

least five minutes should

be

allowed before

alignment is carried out. With the monitor being driven from the

game signal, short

TP601

to

TP31.

Adjust

VR351

until the picture

stops sliding horizontally. Remove the short.

7.0

HORIZONTAL

VIDEO POSITION

If

the video is

off

center on the raster, some compensation can be

made by adjusting

this

control.

8.0 VERTICAL RASTER POSITION ADJUSTMENT

If

the video Is

off

center vertically, (short dimension

of

picture tube)

some compensation can be made by turning the vertical raster posl-

tlon control.

9.0 HORIZONTAL RASTER POSITION

ADJUSTMENT

If the video

Is

off

center horizontally (long dimension

of

the picture

tube), somecompensationcan be made by moving thehorizontal ras-

ter position adjustment jumper to either positions

"A"

or

"L".

NOTE:

This adjustment Is not provided on Model

K4903.

10.0 HORIZONTAL WIDTH ADJUSTMENT

The

horizontal width coll ls a hexagonal tuning tool adjustment. This

control must

be

adjusted slowly,

If

necessary, until the picture

or

test pattern attains the correct horizontal proportions.

INSTALLATION AND SERVICE INSTRUCTIONS

NOTE: All

of

the

followlng procedures have been performed

at

the

factory

and

should

require no further

attention.

If

the

monitor

is serviced for any reason, it should

be

observed afterward to determine whether

any

of

these procedures need

to

be performed again.

OUTLINE

OF

CONVERGENCE AND SET-UP

PROCEDURE

1.0 DEGAUSSING: Demagnetize the shadow mask and

all

surrounding metal parts

with

an external degaussing

coil.

2.0 PURITY:

Adjust

the

purity

magnets

aAd

the

yoke position.

3.0

STATIC

CONVERGENCE: Converge

Red

and Blue on

the screen.

4.0 DYNAMIC CONVERGENCE: Converge

Red

and Blue at

the edges

of

the screen.

5.0 WHITE BALANCE:

Set

Gray and

White

brightness track-

ing.

NOTE: Number 2.0 and 3.0

adjustments

interact.

1.0 DEGAUSSING

The

monitor

Is equipped

with

an automatic degaussing

circuit. However,

if

theCRT shadow mask has become ex-

cessively magnetized,

It

may be necessary to degauss

it

with a manual coll. Do not

switch

the coil OFF while the

raster shows any effect from the coil.

2.0 COLOR PURITY ADJUSTMENT

2.1

For best results,

it

Is recommended that the purity ad-

justment be made in the final monitor location.

If

the

monitor will be moved, perform this adjustment with It

facing west

or

east. The monitor

must

have been

operating

15

minutes prior

to

this

procedure.

2.2

Set the converger assembly on the CRT neck

with

the

center

line

(of the Purity Adjustment Magnet) over the

gap between grids no. 3 and

4.

(See Figures 2 and

6)

2.3

Make certain

that

themagnetic ring-pairs are intheircor-

rect positions before starting procedure.

This produces a zero-correctlon condition on the CRT

beam and helps

facilitate

adjustments.

2.4

Vertlcal raster position control must be at the center

of

its

rotation.

2.5

Remove the

R-G-B

signal from the monitor.

2.6

Turn the Green Cut

2.8 Pull the DeflectIon Yoke backward so

that

theGreen belt

wlll appear. (See Fig.

4)

2.9

Decrease

the

horizontal

width

of

the raster,

if

necessary,

in order

to

be

able

to

see the right and

left

edges

of

the

raster.

2.10

Move the

two

Purity Magnets

with

respect to each other

In

order

to

center the raster horizontally on the screen

and the Green belt on the raster horizontally.

2.11

Push the Deflectlon Yoke forward gradually and fix

It

at

the place where the Green screen becomes uniform

throughout.

2.12

Turn the Cut

off

and Drive Controls and confirm that

each

Is uniform.

2.13

If

the

color

Is

not

uniform, re-adjust It, moving the Purity

Magnets slightly.

3.0 STATIC CONVERGENCE ADJUSTMENT

4-Pole Magnets and 6-Pole Magnets are for static

convergence. "

3.1

A cross hatch signal should

be

connected

to

the

monitor.

3.2

A

pair

of

4-Pole Convergence Magnets

Is

provided

and adjusted to converge the blue and red beams

(See Fig.

6).

When the Pole opens to the left and

right

45

° symmetrically, the magnetic field maxi-

mizes.

Red

and blue beams move to the left and

right

(See

Fig.

5).

Variation

of

the angle between

the tabs adjusts the convergence

of

red

vertical lines.

3.3

When both 4-Pole Convergence Magnet Tabs are

rotated as a pair, the convergence

of

the red and

blue horizontal lines Is adjusted.

3.4

A

pair

of

6-Pole Convergence Magnets

ts

also pro•

vlded and adjusted to converge the magenta (red

+ blue) to green beams

(See

When the

Pole opens to the left and right 30" symmetrlcalty,

the magnetic fleld

Is

maximized.

Red

and blue

beams both move to the left and right

(See

Fig.

OSCILLOSCOPE WAVEFORM PATTERNS

The

waveforms

areas observed on the

wide

band

oscilloscope

with

the

monitor

turned

to

a reasonably

strong

signal and a normal picture. The voltages shown on each waveform are the approximate peak amplitudes.

If

the waveforms are observed on the oscllloscope

with

a poor high frequency response, the corner

of

the

pulses

will

tend

to

more

rounded

than

those

shown

and

the

amplitude

of

anyhlgh

frequency

pulsewill tend

to

be

less.
