SAFETY

CHECK-OUT

After

correcting

the

original

service

problem,

perform

the

following

safety

checks

before

releasing

the

set

to

the

customer:

1.

Check

the

area

of

your

repair

for

unsoldered

or

poorly-soldered

connections.

Check

the

entire

board

surface

for

solder

splashes

and

bridges.

2.

Check

the

interboard

wiring

to

ensure

that

no

wires

are

“pinched”

or

contact

high-wattage

resistors.

3.

Look

for

unauthorized

replacement

parts,

par-

ticularly

transistors,

that

were

installed

during

a

previous

repair.

Point

them

out

to

the

customer

and

recommend

their

replacement.

In

are

On

Beta

are

on

the

together

with

the

signals.

In

this

Beta

system,

audio

signals

are

recorded

first,

using

the

2

then

video

are

recorded

over

the

with

an

azi-

muth

offset,

using

the

2

heads.

Beta

hi-fi

audio

signals

are

frequency-modulated

and

recorded

on

so

you

can
