SAFETY
CHECK-OUT
After
correcting
the
original
service
problem,
perform
the
following
safety
checks
before
releasing
the
set
to
the
customer.
Check
the
area
of
your
repair
for
unsoldered
or
poorly-soldered
connections.
Check
the
entire
board
surface
for
solder
splashes
and
bridges.
Check
the
interboard
wiring
to
ensure
that
no
wires
are
"pinched"
or
contact
high-wattage
resistors.
Look
for
unauthorized
replacement
parts,
particularly
transistors,
that
were
installed
during
a
previous
repair.
Point
them
out
to
the
customer
and
recommend
their
replacement.
