SAFETY PRECAUTIONS
1. PRODUCT SAFETY SERVICING GUIDELINES FOR CAMERA 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
ANY RESULTING 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.
WHILE SERVICING, USE AN ISOLATION TRANSFORMER FOR PROTEC-
TION FROM A.C. LINE SHOCK.
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 MODULES WHICH ARE
TRANSPORTED 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 REIN-
STALLED PER ORIGINAL DESIGN. BE SURE THAT THE SAFETY PUR-
POSE OF THE POLARIZED LINE PLUG HAS NOT BEEN DEFEATED.
3. SOLDERING MUST BE INSPECTED TO DISCOVER POSSIBLE COLD
SOLDER JOINTS, SOLDER SPLASHES OR SHARP SOLDER POINTS.
BE CERTAIN TO REMOVE ALL LOOSE FOREIGN PARTICLES.
4. CHECK FOR PHYSICAL EVIDENCE OF DAMAGE OR DETERIORATION
TO PARTS AND COMPONENTS. FOR FRAYED LEADS, DAMAGED IN-
SULATION (INCLUDING A.C. CORD). AND REPLACE IF NECESSARY
FOLLOW ORIGINAL LAYOUT, LEAD LENGTH AND DRESS.
5. NO LEAD OR COMPONENT SHOULD TOUCH A RECIVING TUBE OR
A RESISTOR RATED AT 1 WATT OR MORE. LEAD TENSION AROUND
PROTRUNING METAL SURFACES MUST BE AVOIDED.
6. ALL CRITICAL COMPONENTS SUCH AS FUSES, FLAMEPROOF RESIS-
TORS, CAPACITORS, ETC. MUST BE REPLACED WITH EXACT FAC-
TORY TYPES, DO NOT USE REPLACEMENT COMPONENTS OTHER
THAN THOSE SPECIFIED OR MAKE UNRECOMMENDED CIR- CUIT
MODIFICATIONS.
7. AFTER RE-ASSEMBLY OF THE SET ALWAYS PERFORM AN A.C. LEAK-
AGE TEST ON ALL EXPOSED METALLIC PARTS OF THE CABI- NET,
(THE CHANNEL SELECTOR KNOB, ANTENNA TERMINALS. HAN- DLE
AND SCREWS) TO BE SURE THE SET IS SAFE TO OPERATE WITH-
OUT DANGER OF ELECTRICAL SHOCK. DO NOT USE A LINE ISOLA-
TION TRANSFORMER DURING THIS TEST USE AN A.C. VOLT- ME-
TER, HAVING 5000 OHMS PER VOLT OR MORE SENSITIVITY, IN THE
FOLLOWING MANNER; CONNECT A 1500 OHM 10 WATT RESISTOR,
PARALLELED BY A .15 MFD. 150.V A.C TYPE CAPACITOR BETWEEN
AKNOWN GOOD EARTH GROUND (WATER PIPE, CON- DUIT, ETC.)
AND THE EXPOSED METALLIC PARTS, ONE AT A TIME. MEASURE THE
A.C. VOLTAGEACROSS 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 ANY VALUE EXCEEDING
THIS LIMIT CONSTITUTES A POTENTIAL SHOCK HAZARD AND MUST
BE CORRECTED IMMEDIATELY.
SUBJECT: GRAPHIC SYMBOLS
THE LIGHTNING FLASH WITH APROWHEAD SYMBOL. WITHIN
AN EQUILATERAL TRIANGLE, IS INTENDED TO ALERT THE
SERVICE PERSONNEL TO THE PRESENCE OF UNINSULATED
“DANGEROUS VOLTAGE” THAT MAY BE OF SUFFICIENT MAG-
NITUDE TO CONSTITUTE A RISK OF ELECTRIC SHOCK.
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.
SUBJECT : X-RADIATION
1. BE SURE PROCEDURES AND INSTRUCTIONS TO ALL SERVICE PER-
SONNEL COVER THE SUBJECT OF X-RADIATION. THE ONLY PO-
TEN- TIAL SOURCE OF X-RAYS IN CURRENT T.V. RECEIVERS IS THE
PIC- TURE 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. OP-
ERA- TION AT HIGHER VOLTAGES MAY CAUSE A FAILURE OF THE
PIC- TURE TUBE OR HIGH VOLTAGE SUPPLY AND, UNDER CERTAIN
CIR- CUMSTANCES, MAY PRODUCE RADIATION IN EXCESS OF DE-
SIRABLE 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 ESSNTIAL THAT SERVICE PERSONNEL HAVE AVAILABLE AN AC-
CURATE AND RELIABLE HIGH VOLTAGE METER. THE CALIBRA TION
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 ORGA-
NIZATION REVIEW TEST PROCEDURES SO THAT VOLTAGE REGU-
LATION IS ALWAYS CHECKED AS A STANDARD SERVICING PROCE-
DURE. AND THAT THE HIGH VOLTAGE READING BE RECORDER 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 LON-
GER THAN IS NECESSARY TO LOCATE THE CAUSE OF EXCES SIVE
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 INTE
GRAL IMPLOSION PROTECTION SYSTEM, BUT CARE SHOULD BE
TAKEN TO AVOID DAMAGE DURING INSTALLATION, AVOID SCRATCH-
ING THE TUBE. IF SCRATCHED REPLACE IT.
2. USE ONLY RECOMMENDED FACTORY REPLACEMENT TUBES.
SUBJECT : TIPS ON PROPER INSTALLATION
1. NEVER INSTALL ANY PRODUCT IN A CLOSED-IN RECESS, CUBBY-
HOLE 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 RADIA-
TORS WHERE STEAM LEAKAGE IS A FACTOR, ETC.
3. AVOID PALCEMENT WHERE DRAPERIES MAY OBSTRUCT REAR
VENTING. THE CUSTOMER SHOULD ALSO AVOID THE USE OF DEC-
ORATIVE SCARVES OR OTHER COVERINGS WHICH MIGHT OB-
STRUCT VENTILATION.
4. WALL AND SHELF MOUNTED INSTALLATIONS USING A COMMER-
CIAL MOUNTING KIT. MUST FOLLOW THE FACTORY APPROVED

2. SERVICING PRECAUTIONS
CAUTION : Before servicing the CAMERA covered by this
service data and its supplements and addends, read and
follow the
SAFETY PRECAUTIONS. NOTE :
if unforeseen
circumstances create conflict between the following servic-
ing precautions and any of the safety precautions in this
publications, always follow the safety precautions.
Remembers Safety First:
General Servicing Precautions
1. Always unplug the CAMERA AC power cord from the AC
power source before:
(1) Removing or reinstalling any component, circuit
board, module, or any other assembly.
(2) Disconnection or reconnecting any internal electrical
plug or other electrical connection.
(3) Connecting a test substitute in parallel with an electro-
lytic capacitor.
Caution : A wrong part substitution or incorrect polar-
ity installation of electrolytic capacitors may result in
an explosion hazard.
2. Do not spray chemicals on or near this CAMERA or any
of its assemblies.
3. Unless specified otherwise in this service data, clean
electrical contacts by applying an appropriate contact
cleaning solution to the contacts with a pipe cleaner, cot-
ton-tipped swab, or comparable soft applicator. Unless
specified otherwise in this service data, lubrication of
contacts is not required.
4. Do not defeat any plug/socket B+ voltage interlocks with
whitch instruments covered by this service manual might
be equipped.
5. Do not apply AC power to this CAMERA and/or any of its
electrical assemblies unless all solid-state device heat
sinks are cerrectly installed.
6. Always connect test instrument ground lead to the ap-
propriate ground before connection the test instrument
positive lead. Always remove the test instrument ground
lead last.
Insulation Checking Procedure
Disconnect the attachment plug from the AC outlet and turn
the power on. Connect an insulation resistance meter(500V)
to the blades of the attachment plug. The insulation re-
sistance between each blade of the attachment plug and
accessible conductive parts (Note 1) should be more than
1Mohm.
Note 1 : Accessible Conductive Parts including Metal pan-
els, Input terminals, Earphone jacks, etc.
Electrostatically Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged
easily by static electricity. Such components commonly are
called Electrostatically Sensitive (ES) Devices. Examples
of typical ES devices are integrated circuits and some field
effect transistors and semiconductor chip components.
The following techniques should be used to help reduce the
incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor compo-
nent or semiconductor-equipped assembly, drain off any
electrostatic charge on your body by touching a known
earth ground. Alternatively, obtain and wear a com-
mercially available discharging wrist strap device, which
should be removed for potential shock reasons prior to
applying power to the unit under test.
2. After removing an electrical assembly equipped with ES
devices, place the assembly on a conductive surface
such as aluminum foil, to prevent electrostatic charge
buildup or exposure of the assembly.
3. Use only a grouned-tip soldering iron to solder or unsol-
der ES devices.
4. Use only an anti-static solder removal device. Some sol-
der removal devices not classified a “anti-static” can gen-
erate electrical charges sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can gener-
ate electrical charge sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protec
tive package until immediately before you are ready to in-
stall it. (Most replacement ES devices are packaged with
leads electrically shorted together by conductive foam,
aluminum foil, or comparable conductive material).
7. Immediately before removing the protective material from
the leads of a replacement ES device, touch the protec-
tive material to the chassis or circuit assembly into which
the device will be installed.
Caution : Be sure no power is applied to the chassis or
circuit, and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged
replacement ES devices. (Normally harmless motion such
as the brushing together of your clothes fabric or the lift-
ing of your foot from a carpeted floor can generate static
electricity sufficient to damage an ES device.)
