SERVICING PRECAUTIONS

CAUTION: Before servicing receivers covered by this

9. Use with this receiver only the test fixtures specified in

service manual and its supplements and addenda, read

and follow the SAFETY PRECAUTIONS on page 3 of this

publication.

this service manual.

CAUTION: Do not connect the test fixture ground strap

to any heat sink in this receiver.

NOTE: If unforeseen circumstances create conflict

between the following servicing precautions and any of the

safety precautions on page 3 of this publication, always

follow the safety precautions. Remember: Safety First.

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 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

known earth ground. Alternatively, obtain and wear a

commercially available discharging wrist strap device,

which should be removed to prevent 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 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 with leads electrically shorted together by

conductive foam, aluminum foil or comparable

conductive material).

General Servicing Precautions

1. Always unplug the receiver AC power cord from the AC

power 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 with an

electrolytic capacitor in the receiver.

CAUTION: A wrong 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 with an

appropriate high voltage meter or other voltage

measuring device (DVM, FETVOM, etc) equipped with

a suitable high voltage probe.

Do not test high voltage by "drawing an arc".

3. Discharge the picture tube anode only by (a) first

connecting one end of an insulated clip lead to the

degaussing or kine aquadag grounding system shield

at the point where 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

with high voltage.

4. Do not spray chemicals on or near this receiver or any

of its assemblies.

5. Unless specified otherwise in this service manual,

clean electrical contacts only by applying the following

mixture to the contacts with a pipe cleaner, cotton-

tipped stick or comparable non-abrasive applicator;

10% (by volume) Acetone and 90% (by volume)

isopropyl alcohol (90%-99% strength)

7. Immediately before removing the protective material

from the leads of a replacement ES device, touch the

protective material to the chassis or circuit assembly

into which the device will be installed.

CAUTION: This is a flammable mixture.

Unless specified otherwise in this service manual,

lubrication of contacts in not required.

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. (Otherwise 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.)

6. Do not defeat any plug/socket B+ voltage interlocks

with which receivers covered by this service manual

might be equipped.

7. Do not apply AC power to this instrument and/or any of

its electrical assemblies unless all solid-state device

heat sinks are correctly installed.

8. Always connect the test receiver ground lead to the

receiver chassis ground before connecting the test

receiver positive lead.

Always remove the test receiver ground lead last.

temperature within 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 well tinned.

4. Thoroughly clean the surfaces to be soldered. Use a

mall wire-bristle (0.5 inch, or 1.25cm) brush with a

metal handle.

Do not use freon-propelled spray-on cleaners.

5. Use the following unsoldering technique

a. Allow the soldering iron tip to reach normal

temperature.

"Small-Signal" Discrete Transistor

Circuit Board Foil Repair

At Other Connections

Excessive heat applied to the copper foil of any printed

circuit board will weaken the adhesive that bonds the foil

to the circuit board causing the foil to separate from or

"lift-off" the board. The following guidelines and

procedures should be followed whenever this condition is

encountered.

Use the following technique to repair the defective copper

pattern at connections other than IC Pins. This technique

involves the installation of a jumper wire on the

component side of the circuit board.

1. Remove the defective copper pattern with a sharp

knife.

Remove at least 1/4 inch of copper, to ensure that a

hazardous condition will not exist if the jumper wire

opens.

At IC Connections

To repair a defective copper pattern at IC connections use

the following procedure to install a jumper wire on the

copper pattern side of the circuit board. (Use this

technique only on IC connections).

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 wire 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.

1. Carefully remove the damaged copper pattern with a

sharp knife. (Remove only as much copper as

absolutely necessary).

2. carefully scratch away 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

wire and carefully crimp it around the IC pin. Solder the

IC connection.

Carefully crimp and solder the connections.

CAUTION: Be sure the insulated jumper wire is

dressed so the it does not touch components or sharp

edges.

4. Route the jumper wire along the path of the out-away

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 wire.
