PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO - VIDEO PRODUCTS

CAUTION : DO NOT ATTEMPT TO MODIFY THIS PRODUCT IN ANY WAY.

NEVER PERFORM CUSTOMIZED INSTALLATIONS WITHOUT MANUFAC-

TURER'S APPROVAL. UNAUTHORIZED MODIFICATIONS WILL NOT ONLY VOID

THE WARRANTY, BUT MAY LEAD TO YOUR BEING LIABLE FOR ANT RESULT-

ING PROPERTY DAMAGE OR USER INJURY.

SERVICE WORK SHOULD BE PERFORMED ONLY AFTER YOU ARE THOR-

OUGHLY 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.

SUBJECT : X-RADIATION

1. BE SURE PROCEDURES AND INSTRUCTIONS TO ALL SERVICE PERSON-

NEL COVER THE SUBJECT OF X-RADIATION. THE ONLY POTENTIAL

SOURCE OF X-RAYS IN CURRENT T.V. RECEIVERS IS THE PICTURE TUBE.

HOWEVER, THIS TUBE DOES NOT EMIT X-RAYS WHEN THE HIGH VOLT-

AGE IS AT THE FACTORY SPECIFIED LEVEL. THE PROPER VALUE IS

GIVEN IN THE APPLICABLE SCHEMATIC. OPERATION AT HIGHER VOLT-

AGES MAY CAUSE A FAILURE OF THE PICTURE TUBE OR HIGH VOLTAGE

SUPPLY AND UNDER CERTAIN CIRCUMSTANCES, AMY PRODUCE RADIA-

TION IN EXCESS OF DESIRABLE LEVELS.

WHILE SERVICING, USE AN ISOLATION TRANSFORMER FOR PROTECTION

FROM A.C. LINE SHOCK.

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.

SAFETY CHECKS

AFTER THE ORIGINAL SERVICE PROBLEM HAS BEEN CORRECTED, A CHECK

SHOULD BE MADE OF THE FOLLOWING:

3. IT IS ESSENTIAL THAT SERVICE PERSONNEL HAVE AVAILABLE AN ACCU-

RATE AND RELIABLE HIGH VOLTAGE METER. THE CALIBRATION OF THE

METER SHOULD BE CHECKED PERIODICALLY 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

PRODUCT WITH A PROBLEM OF EXCESSIVE HIGH VOLTAGE, AVOID

BEING UNNECESSARILY CLOSE TO THE PICTURE TUBE AND THE HIGH

VOLTAGE SUPPLY. DO NOT OPERATE THE PRODUCT 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: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 MODULES WHICH ARE TRANS-

PORTED TO AND FROM THE REPAIR SHOP.

2. NEVER RELEASE A REPAIR UNLESS ALL PROTECTIVE DEVICES SUCH AS

INSULATORS, BARRIERS, COVERS, SHIELDS, STRAIN RELIEFS, POWER

SUPPLY CORDS, AND OTHER HARDWARE HAVE BEEN REINSTALLED PER

ORIGINAL DESIGN. BE SURE, THAT THE SAFETY PURPOSE OF THE

POLARIZED LINE PLUG HAS NOT BEEN DEFEATED.

3. SOLDERING MUST BE INSPECTED TO DISCOVER POSSIBLE COLD SOL-

DER JOINTS, SOLDER SPLASHES OF SHARP SOLDER POINTS. BE CER-

TAIN TO REMOVE ALL LOOSE FOREIGN PARTICLES.

4. CHECK FOR PHYSICAL EVIDENCE OF DAMAGE OR DETERIORATION TO

PARTS AND COMPONENTS, FOR FRAYED LEADS, DAMAGED INSULATION

(INCLUDING A.C. CORD), AND REPLACE IF NECESSARY. FOLLOW ORIGI-

NAL LAYOUT, LEAD LENGTH AND DRESS.

5. NO LEAD OR COMPONENT SHOULD TOUCH A RECEIVING TUBE OR A

RESISTOR RATED AT 1 WATT OR MORE. LEAD TENSION AROUND PRO-

TRUDING METAL SURFACES MUST BE AVOIDED.

6. ALL CRITICAL COMPONENTS SUCH AS FUSES, FLAMEPROOF RESISTOR,

CAPACITORS, ETC. MUST BE REPLACED WITH EXACT FACTORY TYPES.

DO NOT USE REPLACEMENT COMPONENTS OTHER THAN THOSE SPECI-

FIED OR MAKE UNRECOMMENDED CIRCUIT MODIFICATIONS.

SUBJECT : IMPLOSION

1. ALL DIRECT VIEWED PICTURE TUBES ARE EQUIPPED WITH AN INTEGRA

IMPLOSION PROTECTION SYSTEM. BUT CARE SHOULD BE TAKEN TO

AVOID DAMAGE DURING INSTALLATION. AVOID SCRATCHING THE

TUBE. OF SCRATCHED REPLACE IT.

7. AFTER RE-ASSEMBLY OF THE STE ALWAYS PERFORM AN A.C. LEAKAGE

TEST ON ALL EXPOSED METALLIC PARTS OF THE CABINET. (THE CHAN-

NEL SELECTOR KNOB, ANTENNA TERMINALS, HANDLE AND SCREWS) TO

BE SURE THE SET IS SAFE TO OPERATE WITHOUT DANGER OF ELECTRI-

CAL 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 CAPACI-

TOR BETWEEN A KNOWN GOOD EARTH GROUND (WATER POPE, CON-

DUIT, ETC.) AND THE EXPOSED METALLIC PARTS, ONE AT A TIME.

MEASURE THE A.C. VOLTAGE ACROSS THE COMBINATION OF 1500 OHM

RESISTOR AND .15 MFD CAPACITOR. REVERSE THE A.C. PLUG AND

REPEAT A.C. VOLTAGE MEASUREMENTS FOR EACH EXPOSED METALLIC

PART. VOLTAGE MEASURED MUST NOT EXCEED .75 VOLTS R.M.S THIS

CORRESPONDS TO 0.5 MILLIAMP A.C. NAY VALUE EXCEEDING THIS LIMIT

CONSTITUTES A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED

IMMEDIATELY.

PRODUCT SAFETY SERVICING GUIDELINES FOR COLOR TELEVISION RECEIVERS

CAUTION : Do not attempt to modify this product in any way. Unau-

thorized 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 guide-

lines. To do otherwise, increases the risk of potential hazards and

injury to the user.

GRAPHIC SYMBOLS :

The lightning flash with arrowhead symbol,

within an equilateral triangle, is intended to alert

the service personnel to the presence of uninsu-

lated “dangerous voltage” that may be of suffi-

cienty magnitude to constitute a risk of electric

shock.

SAFETY CHECKS

The exclamation point within an equilateral tri-

angle is intended to alert the service personnel

to the presence of important safety information

in service literature.

After the original service problem has been corrected, a check should

be made of the following:

SUBJECT : FIRE & SHOCK HAZARD

Fuse symbol is printed on pcb adjacent to the

fuse, with “RISK OF FIRE REPLACE FUSE AS

MARKED”. The symbol is explained in the ser-

vice manual with the following wording or equiv-

alent.

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.

“CAUTION : FOR CONTINUED PROTECTION AGAINST FIRE

HAZARD, REPLACE ONLY WITH SAME TYPE (4A, 125V)” and

“

ATTENTION: AFIN D’ASSU UNE PROTECTION PERMANENTE

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 for-

eign particals.

MENT PAR UN FUSIBLE DE MEME TYPE ET DE ”4A, 125V”.

SUBJECT : X-RADIATION

4. Check for physical evidence of damage or deterioration to parts

and components, and replace if necessary follow original layout,

lead length and dress.

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 appli-

cable schematic. Operation at higher voltages may cause a failure

of the picture tube or high voltage supply and, under certain cir-

cumstances, 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.

5. No leads or components should touch a receiving tube or a resistor

rated at 1 watt or more. Lead tension around protruding metal sur-

faces 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 3. It is essential that the serviceman has available an accurate and

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

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.

manner : connect a 1500 ohm 10 watt resistor, paralleled by a 15 4. When the high voltage circuitry is operating properly there is no

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 imme-

diately.

possibility of an X-radiation problem. Every time a color chassis is

serviced, the brightness should be run up and down while monitor-

ing the high voltage with a meter to be certain that the high voltage

does not exceed the specified value and that it is regulating cor-

rectly. 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.

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 cus-

tomized installations.

SUBJECT : IMPLOSION

1. All direct viewed picture tubes are equipped with an integral implo-

sion 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.

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.

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 installa-

tions 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.
