Some

video

modes

do

not

fill

the

screen

to

the

edge

of

the

monitor.

There

is

no

single

answer

to

solve

the

There

is

a

tendency

to

have

this

on

timings.

■•

Adjust

the

"CONTRAST"

and

"BRIGHTNESS"

on

the

OSD

(page

5).

We

have

come

across

several

brands

of

SVGA

boards

that

have

an

excessive

video

output

level

which

creates

a

fuzzy

picture

at

max

contrast.

•

Trip

the

power

cycle*.

Picture

bounces

or

wavy

oscillations

Isolate

and

eliminate

any

potential

sources

of

electric

or

magnetic

fields.

Common

causes

for

this

symptom

are

electric

fans,

fl

uorescent

lighting,

laser

printers,

and

so

on.

▪

If

you

have

another

monitor

close

to

this

monitor,

increase

the

distance

between

them

to

reduce

the

interference.

Try

plugging

the

monitor

into

a

different

AC

outlet,

preferably

on

a

different

circuit.

Try

the

monitor

on

a

completely

different

computer

in

a

differnt

room.

Picture

appears

to

be

ghosting

Eliminate

the

use

of

video

cable

extension

cables

and/or

video

switch

boxes

if

this

symptom

occurs.

Excessive

cable

length

or

weak

connections

can

produce

this

symptom.

A

fine

horizontal

line

(wire)

is

visible

••0

This

wire

stabilizes

the

vertically

striped

Aperture

Grille.

This

Aperture

Grille

allows

more

light

to

pass

through

to

the

screen

giving

the

Trinitron

CRT

more

color

and

brightness.

Wavy

or

elliptical

(moire)

pattern

is

visible

Due

to

the

relationship

between

resolution,

monitor

dot

pitch

and

the

pitch

of

some

image

patterns,

certain

screen

backgrounds,

especially

gray,

sometimes

show

moire.

This

can

only

be

eliminated

by

changing

your

desktop

pattern.

Just

after

turning

the

monitor

on,

a

"boon"

noise

is

heard

Just

after

turning

the

monitor

on,

a

noise

may

be

heard

for

about

3

seconds.

This

noise

is

not

failure,

it

is

caused

by

the

auto

-

degauss

cycle*.

*

The

Auto

-degauss

function

demagnetizes

the

metal

frame

of

the

CRT

to

obtain

a

neutral

field

for

uniform

color

reproduction.

If

a

second

degauss

cycle

is

needed,

allow

a

minimum

interval

of

20

minutes

for

the

best

result.

•

If

the

problem

persists,

call

your

authorized

Sony

dealer

from

a

location

near

your

monitor.

•

Note

the

model

name

and

the

serial

number

of

your

monitor.

Also

note

the

make

and

name

of

your

computer

and

video

board.
