PRODUCT SAFETY SERVICING GUIDELINES FOR COLOR TELEVISION RECEIVERS
CAUTION
: Do not attempt to modify this product in any way. Unauthorized modifications will not only void the warranty, but may lead to
your being liable for any resulting property damage or user injury.
Service work should be performed only after you are thoroughly
familiar with all of the following safety checks and servicing
guidelines. To do otherwise, increases the risk of potential hazards
and injury to the user.
SAFETY CHECKS
After the original service problem has been corrected, a check should
be made of the following:
SUBJECT : FIRE & SHOCK HAZARD
1. Be sure that all components are positioned in such a way as to
avoid possibility of adjacent component shorts. This is especially
important on those chassis which are transported to and from the
repair shop.
2. Never release a repair unless all protective devices such as insula-
tors, barriers, covers, shields, strain reliefs, and other hardware
have been reinstalled per original design.
3. Soldering must be inspected to discover possible cold solder
joints,frayed leads, damaged insulation (including A.C. cord),
solder splashes or sharp solder points. Be certain to remove all
loose foreign particals.
4. Check for physical evidence of damage or deterioration to parts
and components, and replace if necessary follow original layout,
lead length and dress.
5. No leads or components should touch a receiving tube or a resistor
rated at 1 watt or more. Lead tension around protruding metal surfaces must be avoided.
6. All critical components such as fuses, flameproof resistors, capaci-
tors, etc. must be replaced with exact factory types. Do not use
replacement components other than those specified or make
unrecommended circuit modifications.
7. After re-assembly of the set always perform an A.C. leakage test
on all exposed metallic parts of the cabinet, (the channel selector
knob, antenna terminals, handle and screws) to be sure the set is
safe to operate without danger of electrical shock. Do not use a
line isolation transformer during this test. Use an A.C. Voltmeter,
having 5000 ohms per volt or more sensitivity, in the following
manner : connect a 1500 ohm 10 watt resistor, paralleled by a 15
mfd. 150V A.C. type capacitor between a known good earth
ground (9water pipe, conduit, etc.) and the exposed metallic parts,
one at a time. Measure the A.C. voltage across the combination of
1500 ohm resistor and 0.15 MFD capacitor. Reverse the A.C. plug
and repeat A.C. voltage measurements for each exposed metallic
part. Voltage measured must not exceed 0.75 volts R.M.S. This
corresponds to 0.5 milliamp A.C. Any value exceeding this limit
constitutes a potential shock hazard and must be corrected immediately.
GRAPHIC SYMBOLS :
The lightning flash with arrowhead symbol,within
an equilateral triangle, is intended to alert the
service personnel to the presence of uninsulated “dangerous voltage” that may be of sufficienty magnitude to constitute a risk of electric
shock.
The exclamation point within an equilateral triangle is intended to alert the service personnelto
the presence of important safety informationin
service literature.
Fuse symbol is printed on pcb adjacent to the
fuse, with “RISK OF FIRE REPLACE FUSE AS
MARKED”. The symbol is explained in the service manual with the following wording or equivalent.
“CAUTION :
FOR CONTINUED PROTECTION AGAINST FIRE
HAZARD, REPLACE ONLY WITH SAME TYPE (5A, 125V)” and
“ATTENTION:
AFIN D’ASSU UNE PROTECTION PERMANENTE
CONTRE LES RISQUES D’INCENDIE, REMPLACER UNIQUEMENT PAR UN FUSIBLE DE MEME TYPE ET DE ”5A, 125V”.
SUBJECT : X-RADIATION
1. Be sure procedures and instructions to all service personnel cover
the subject of X-rays in current T.V. receivers is the picture tube.
However, this tube does not emit X-rays when the high voltage is
at the factory specified level. The proper value is given in the applicable schematic. Operation at higher voltages may cause a failure
of the picture tube or high voltage supply and, under certain circumstances, may produce radiation in excess of desirable levels.
2. Only factory specified C.R.T. anode connectors must be used.
Degaussing shields also serve as X-ray shield in color sets.
Always re-install them.
3. It is essential that the serviceman has available an accurate and
reliable high voltage meter. The calibration of the meter should be
checked perio - dically against a reference standard. Such as the
one available at your distributor.
4. When the high voltage circuitry is operating properly there is no
possibility of an X-radiation problem. Every time a color chassis is
serviced, the brightness should be run up and down while monitoring the high voltage with a meter to be certain that the high voltage
does not exceed the specified value and that it is regulating correctly. We suggest that you and your service organization review
test procedures so that voltage regulation is always checked as a
standard servicing procedure. And that the high voltage reading be
recorded on each customer’s invoice.
5. When troubleshooting and making test measurements in a receiver
with a problem of excessive high voltage, avoid being
unnecessarily
close to the picture tub eand the high voltage compartment.
Do not operate the chassis longer than is necessary to locate the
cause of excessive voltage.
6. Refer to HV, B+and Shutdown adjustment procedures described in
the appropriate schematic and diagrams(where used).

SUBJECT : IMPLOSION
1. All direct viewed picture tubes are equipped with an integral implosion protection system, but care should be taken to avoid damage
during installation. Avoid scratching the tube. If scratched, replace
it.
2. Use only recommended factory replacement tubes.
SUBJECT : TIPS ON PROPER INSTALLATION
1. Never install any receiver in closed-in recess, cubbyhole or closely
fitting shelf space over, or close to heat duct, or in the path of
heated air flow.
2. Avoid conditions of high humidity such as : Outdoor patio installations where dew is a factor. Near steam radiators where steam
leakage is a factor, etc.
3. Avoid placement where draperies may obstruct rear venting. The
customer should also avoid the use of decorative scarves or other
coverings which might obstruct ventilation.
4. Wall and shelf mounted installations using a commercial mounting
kit, must follow the factory approved mounting instructions. A
receiver mounted to a shelf or platform must retain its original
feet(or the equivalent thickness in spacers) to provide adequate
are flow across the bottom, bolts or screws used for fasteners
must not touch and parts or wiring. Perform leakage test on customized installations.
5. Caution customers against the mounting of a receiver on sloping
shelf or a tilted position, unless the receiver is properly secured.
6. A receiver on a roll-about cart should be stable on its mounting to
the cart. Caution the customer on the hazards of trying to roll a cart
with small casters across thresholds or deep pile carpets.
7. Caution customers against the use of a cart or stand which has not
been listed by underwriters laboratories, inc. For use with their
specific model of television receiver or generically approved for
use with T.V.’s of the same or larger screen size.
