SAFETY PRECAUTIONS
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in
the Schematic Diagram and Replacement Parts List.
It is essential that these special safety parts should be replaced ith the same components as recommended in this manual to
prevent X-RADIATION, Shock, Fire, or other Hazards.
Do not modify the original design ithout permission of manufacturer.
General Guidance
An isolation Transformer should always be used during
the servicing of a receiver hose chassis is not isolated from
the AC po er line. Use a transformer of adequate po er rating
as this protects the technician from accidents resulting in
personal injury from electrical shocks.
It ill also protect the receiver and it's components from being
damaged by accidental shorts of the circuitry that may be
inadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this TV receiver is blo n,
replace it ith the specified.
When replacing a high attage resistor (Oxide Metal Film
Resistor, over 1W), keep the resistor 10mm a ay from PCB.
Keep ires a ay from high voltage or high temperature parts.
Due to high vacuum and large surface area of picture tube,
extreme care should be used in handling the Picture Tube.
Do not lift the Picture tube by it's Neck.
Before returning the receiver to the customer,
al ays perform an AC leakage current check on the exposed
metallic parts of the cabinet, such as antennas, terminals, etc.,
to be sure the set is safe to operate ithout damage of
electrical shock.
Leakage Current Cold Check(Antenna Cold Check
With the instrument AC plug removed from AC source,
connect an electrical jumper across the t o AC plug prongs.
Place the AC s itch in the on position, connect one lead of
ohm-meter to the AC plug prongs tied together and touch other
ohm-meter lead in turn to each exposed metallic parts such as
antenna terminals, phone jacks, etc.
If the exposed metallic part has a return path to the chassis, the
measured resistance should be bet een 1MΩ and 5.2MΩ.
When the exposed metal has no return path to the chassis the
reading must be infinite.
An other abnormality exists that must be corrected before the
receiver is returned to the customer.
Leakage Current Hot Check (See belo Figure)
Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check.
Connect 1.5K/10 att resistor in parallel ith a 0.15uF capacitor
bet een a kno n good earth ground (Water Pipe, Conduit, etc.)
and the exposed metallic parts.
Measure the AC voltage across the resistor using AC
voltmeter ith 1000 ohms/volt or more sensitivity.
Reverse plug the AC cord into the AC outlet and repeat AC
voltage measurements for each exposed metallic part. Any
voltage measured must not exceed 0.75 volt RMS hich is
corresponds to 0.5mA.
In case any measurement is out of the limits specified, there is
possibility of shock hazard and the set must be checked and
repaired before it is returned to the customer.

precautions on page 3 of this publication, al ays follo the
safety precautions. Remember: Safety First.
General Servicing Precautions
1. Al ays unplug the receiver AC po er cord from the AC
po er source before;
a. Removing or reinstalling any component, circuit board
module or any other receiver assembly.
b. Disconnecting or reconnecting any receiver electrical plug
or other electrical connection.
c.
Connecting a test substitute in parallel ith an electrolytic
capacitor in the receiver.
CAUTION: A rong part substitution or incorrect
polarity installation of electrolytic capacitors may result
in an explosion hazard.
d. Discharging the picture tube anode.
2. Test high voltage only by measuring it ith an appropriate
high voltage meter or other voltage measuring device (DVM,
FETVOM, etc) equipped ith a suitable high voltage probe.
Do not test high voltage by "dra ing an arc".
3. Discharge the picture tube anode only by (a) first connecting
one end of an insulated clip lead to the degaussing or kind
aquadag grounding system shield at the point here the
picture tube socket ground lead is connected, and then (b)
touch the other end of the insulated clip lead to the picture
tube anode button, using an insulating handle to avoid
personal contact ith high voltage.
4. Do not spray chemicals on or near this receiver or any of its
assemblies.
5. Unless specified other ise in this service manual, clean
electrical contacts only by applying the follo ing mixture to
the contacts ith a pipe cleaner, cotton-tipped stick or
comparable nonabrasive applicator; 10% (by volume)
Acetone and 90% (by volume) isopropyl alcohol (90%-99%
strength)
CAUTION: This is a flammable mixture.
Unless specified other ise in this service manual, lubrication
of contacts in not required.
6. Do not defeat any plug/socket B+ voltage interlocks ith
hich receivers covered by this service manual might be
equipped.
7. Do not apply AC po er to this instrument and/or any of its
electrical assemblies unless all solid-state device heat sinks
are correctly installed.
8. Al ays connect the test receiver ground lead to the
receiver chassis ground before connecting the test receiver
positive lead.
Al ays remove the test receiver ground lead last.
9. Use with this receiver only the test fixtures specified in this
service manual.
CAUTION: Do not connect the test fixture ground strap to
any heatsink in this receiver.
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
follo ing techniques should be used to help reduce the
incidence of component damage caused by static by static
electricity.
1. Immediately before handling any semiconductor component
or semiconductor-equipped assembly, drain off any
electrostatic charge on your body by touching a kno n earth
ground. Alternatively, obtain and ear a commercially
available discharging rist strap device, hich should be
removed to prevent potential shock reasons prior to
applying po er to the unit under test.
2. After removing an electrical assembly equipped ith 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 grounded-tip soldering iron to solder or unsolder
ES devices.
4. Use only an anti-static type solder removal device. Some
solder removal devices not classified as "anti-static" can
generate electrical charges sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate
electrical charges sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective
package until immediately before you are ready to install it.
(Most replacement ES devices are packaged ith leads
electrically shorted together by conductive foam, aluminum
foil or comparable conductive material).
7. Immediately before removing the protective material from
the ieads of a replacement ES device, touch the protective
material to the chassis or circuit assembly into hich the
device ill be installed.
CAUTION:Be sure no po er is applied to the chassis or
circuit, and observe all other safety precautions.
8. Minimize bodily motions hen handling unpackaged
replacement ES devices. (Other ise harmless motion such
as the brushing together of your clothes fabric or the lifting
of your foot from a carpeted floor can generate static
electricity sufficient to damage an ES device.)
General Soldering Guidelines
1. Use a grounded-tip, lo - attage soldering iron and
appropriate tip size and shape that ill maintain tip
temperature ithin the range or 500°F to 600°F.
2. Use an appropriate gauge of RMA resin-core solder
composed of 60 parts tin/40 parts lead.
3. Keep the soldering iron tip clean and ell tinned.
4. Thorohly clean the surfaces to be soldered. Use a mall ire
bristle (0.5 inch, or 1.25cm) brush ith a metal handle.
Do not use freon-propelled spray-on cleaners.
5. Use the follo ing unsoldering technique
a. Allo the soldering iron tip to reach normal temperature.
(500°F to 600°F)
b. Heat the component lead until the solder melts.
c. Quickly dra the melted solder ith an anti-static,
suction-type solder removal device or ith solder braid.
CAUTION: Work quickly to avoid overheating the circuit
board printed foil.
6. Use the follo ing soldering technique.
a. Allo the soldering iron tip to reach a normal
temperature (500°F to 600°F)
b. First, hold the soldering iron tip and solder the strand
against the component lead until the solder melts.
SERVICING PRECAUTIONS

- 5 -
c. Quickly move the soldering iron tip to the junction of the
component lead and the printed circuit foil, and hold it
there only until the solder flo s onto and around both the
component lead and the foil.
CAUTION: Work quickly to avoid overheating the circuit
board printed foil.
d. Closely inspect the solder area and remove any excess
or splashed solder ith a small ire-bristle brush.
IC Remove/Replacement
Some chassis circuit boards have slotted holes (oblong) through
hich the IC leads are inserted and then bent flat against the
circuit foil. When holes are the slotted type, the follo ing
technique should be used to remove and replace the IC. When
orking ith boards using the familiar round hole, use the
standard technique as outlined in paragraphs 5 and 6 above.
Removal
1. Desolder and straighten each IC lead in one operation by
gently prying up on the lead ith the soldering iron tip as the
solder melts.
2. Dra a ay the melted solder ith an anti-static suction-
type solder removal device (or ith solder braid) before
removing the IC.
Replacement
1. Carefully insert the replacement IC in the circuit board.
2. Carefully bend each IC lead against the circuit foil pad and
solder it.
3. Clean the soldered areas ith a small ire-bristle brush.
(It is not necessary to reapply acrylic coating to the areas).
"Small-Signal" Discrete Transistor
Removal/Replacement
1. Remove the defective transistor by clipping its leads as
close as possible to the component body.
2. Bend into a "U" shape the end of each of three leads
remaining on the circuit board.
3. Bend into a "U" shape the replacement transistor leads.
4. Connect the replacement transistor leads to the
corresponding leads extending from the circuit board and
crimp the "U" ith long nose pliers to insure metal to metal
contact then solder each connection.
Power Output, Transistor Device
Removal/Replacement
1. Heat and remove all solder from around the transistor leads.
2. Remove the heatsink mounting scre (if so equipped).
3. Carefully remove the transistor from the heat sink of the
circuit board.
4. Insert ne transistor in the circuit board.
5. Solder each transistor lead, and clip off excess lead.
6. Replace heatsink.
Diode Removal/Replacement
1. Remove defective diode by clipping its leads as close as
possible to diode body.
2. Bend the t o remaining leads perpendicular y to the circuit
board.
3. Observing diode polarity, rap each lead of the ne diode
around the corresponding lead on the circuit board.
4. Securely crimp each connection and solder it.
5. Inspect (on the circuit board copper side) the solder joints of
the t o "original" leads. If they are not shiny, reheat them
and if necessary, apply additional solder.
Fuse and Conventional Resistor
Removal/Replacement
1. Clip each fuse or resistor lead at top of the circuit board
hollo stake.
2. Securely crimp the leads of replacement component around
notch at stake top.
3. Solder the connections.
CAUTION: Maintain original spacing bet een the replaced
component and adjacent components and the circuit board
to prevent excessive component temperatures.
Circuit Board Foil Repair
Excessive heat applied to the copper foil of any printed circuit
board ill eaken the adhesive that bonds the foil to the circuit
board causing the foil to separate from or "lift-off" the board.
The follo ing guidelines and procedures should be follo ed
henever this condition is encountered.
At IC Connections
To repair a defective copper pattern at IC connections use the
follo ing procedure to install a jumper ire on the copper
pattern side of the circuit board. (Use this technique only on IC
connections).
1. Carefully remove the damaged copper pattern ith a sharp
knife. (Remove only as much copper as absolutely
necessary).
2. carefully scratch a ay the solder resist and acrylic coating
(if used) from the end of the remaining copper pattern.
3. Bend a small "U" in one end of a small gauge jumper ire and
carefully crimp it around the IC pin. Solder the IC connection.
4. Route the jumper ire along the path of the out-a ay
copper pattern and let it overlap the previously scraped end
of the good copper pattern. Solder the overlapped area and
clip off any excess jumper ire.
At Other Connections
Use the follo ing technique to repair the defective copper
pattern at connections other than IC Pins. This technique
involves the installation of a jumper ire on the component
side of the circuit board.
1. Remove the defective copper pattern ith a sharp knife.
Remove at least 1/4 inch of copper, to ensure that a
hazardous condition ill not exist if the jumper ire opens.
2. Trace along the copper pattern from both sides of the
pattern break and locate the nearest component that is
directly connected to the affected copper pattern.
3. Connect insulated 20-gauge jumper ire from the lead of
the nearest component on one side of the pattern break to
the lead of the nearest component on the other side.
Carefully crimp and solder the connections.
CAUTION: Be sure the insulated jumper ire is dressed so
the it does not touch components or sharp edges.
