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 touching high-wattage resistors.
3. Check that all control knobs, shields, covers, ground
straps, and mounting hardware have been replaced.
Be absolutely certain that you have replaced all the
insulators.
4. Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair.
Point them out to the customer and recommend their
replacement.
5. Look for parts which, though functioning, show
obvious signs of deterioration. Point them out to the
customer and recommend their replacement.
6. Check the line cords for cracks and abrasion.
Recommend the replacement of any such line cord
to the customer.
7. Check the B+ and HV to see if they are specified
values. Make sure your instruments are accurate;
be suspicious of your HV meter if sets always have
low HV.
8. Check the antenna terminals, metal trim, "metallized"
knobs, screws, and all other exposed metal parts for
AC leakage. Check leakage as described below.
Leakage Test
The AC leakage from any exposed metal part to earth
ground and from all exposed metal parts to any exposed
metal part having a return to chassis, must not exceed 0.5
mA (500 microamperes). Leakage current can be measured
by any one of three methods.
1. A commercial leakage tester, such as the Simpson
229 or RCA WT-540A. Follow the manufacturers'
instructions to use these instructions.
2. A battery-operated AC milliammeter. The Data
Precision 245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by
means of a VOM or battery-operated AC voltmeter.
The "limit" indication is 0.75 V, so analog meters must
have an accurate low voltage scale. The Simpson's
250 and Sanwa SH-63Trd are examples of passive
VOMs that are suitable. Nearly all battery-operated
digital multimeters that have a 2 VAC range are
suitable (see Figure A).
How to Find a Good Earth Ground
A cold-water pipe is a guaranteed earth ground. The cover-
plate retaining screw on most AC outlet boxes is also at earth
ground. If the retaining screw is to be used as your earth
ground, verify that it is at ground by measuring the resistance
between it and a cold-water pipe with an ohmmeter. The
reading should be zero ohms. If a cold-water pipe is not
accessible, connect a 60- to 100-watt trouble- light (not a neon
lamp) between the hot side of the receptacle and the retaining
screw. Try both slots, if necessary, to locate the hot side on the
line; the lamp should light at normal brilliance if the screw is at
ground potential (see Figure B).

helps
you
to
correct
problems
you
may
encounter
with
your
TV.
Safety
·
Operate
the
TV
only
with
120
V
AC
.
·
The
plug
is
designed,
for
safety
purposes,
to
fit
in
the
wall
outlet
only
one
way.
If
you
are
unable
to
insert
the
plug
fully
into
the
outlet,
contact
your
dealer.
·
If
any
liquid
or
solid
object
should
fall
inside
the
cabinet,
unplug
the
TV
immediately
and
have
it
checked
by
qualified
personnel
before
operating
it
further.
Installing
·
To
prevent
internal
heat
build-up,
do
not
block
the
ventilation
openings.
·
Do
not
install
the
TV
in
a
hot
or
humid
place,
or
in
a
place
subject
to
excessive
dust
or
mechanical
vibration.
·
The
AC
power
cord
is
attached
to
the
rear
of
the
TV
with
hooks.
Do
not
attempt
to
remove
the
cord
from
these
hooks.
Doing
so
could
cause
damage
to
the
