SAFETY PRECAUTIONS
CAUTION : No modifications of any circuits should be attempted. Service work should be
performed only after you are thoroughly familiar with all of the following safety checks and
servicing guidelines.
SAFETY CHECK
Care should be taken while servicing this analog color display because of the high
voltages used in the deflection circuits. These voltages are exposed in such areas as the
associated Fly-back transformer and yoke circuits.
FIRE & SHOCK HAZARD
 Insert an isolation transformer between the analog color display and AC power
line before servicing the chassis.
 When servicing, pay close attention to the original lead dress especially in the
high voltage circuit area; if a short circuit is found, replace all parts which have
been overheated as a result of the short circuit.
 All the protective devices must be reinstalled per original design.
 Soldering must be inspected for possible cold solder points, frayed leads,
damaged insulation, solder splashes or sharp solder points. Be certain to remove
all foreign materials.
IMPLOSION PROTECTION

SAFETY PRECAUTIONS
X-RAY
WARNING : The only potential source of X-Ray is the picture tube. However when the
high voltage circuitry is operation properly, there is no possibility of an X-
Ray problem. The basic precaution which must be exercised is to keep the
high voltage at the following factory recommended level.
NOTE : It is important to use an accurate, periodically, calibrated high voltage meter.
 To measure the high voltage, use a high-impedance high-voltage meter.
Connect(-) to chassis and (+) to the CRT anode button.
 Turn the Contrast & Brightness Control fully counterclockwise.
 Measure the high voltage. The high voltage meter should indicate the
following factory recommended levels,
 If the upper meter indication exceeds the maximum level, immediate service
is required to prevent the possibility of premature component failure.
 To prevent X-Ray possibility, it is essential to use the specified picture tube.
 The normal high voltage is 27KV or below and must not exceed 29KV at
zero beam current at rated voltage.

SERVICING PRECAUTIONS
CAUTION : Before servicing instruments covered by this service manual, its supplements,
and addendum, please read and follow the SAFETY PRECAUTIONS of this manual.
NOTE : If unforeseen circumstances create conflict between the following servicing
precautions and any of the safety precautions on page 3 of this manual, always follow the
safety precautions.
General Servicing Precautions
1. Always unplug the AC power cord from source before:
 Removing or reinstalling any component, circuit board, module, or any
other instrument assembly.
 Disconnecting or reconnecting any electrical plug or other electrical
connection
 Connecting a test substitute in parallel with an electrolytic capacitor in the
instrument.
CAUTION : A wrong part substitution or incorrect polarity
installation of electrolytic capacitors may result in a explosion.
 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 line grounding system shield at the point where the
picture tube socket ground lead is connected, and then (b) touching 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 any spray chemicals on or near this instrument, or any of its assemblies.
5. Unless otherwise specified in this service manual, only clean electrical contacts by
applying the following mixture to the contacts with a pipe cleaner, cotton-tipped stick,
or comparable nonabrasive applicator:10%(by volume) Aceton and 90%(by volume)
isopropyl alcohol(90%-99% strength).
CAUTION : This is a flammable mixture. Unless specified in this service manual,
lubrication of contacts is not required.

SERVICING PRECAUTIONS
6. Do not damage any plug/socket B+ voltage interlocks with which instruments
covered by this service manual might be equipped.
7. Do not apply AC power to this instrument and/or any other of its electrical
assemblies unless all the solid-state device heat sinks are correctly installed.
8. Always connect the test instrument ground lead to the appropriate instrument chassis
ground before connecting the test instrument positive lead. Always remove the test
instrument ground lead last.
9. Only use the test fixtures specified in this service manual with this instrument.
CAUTION : Do not connect the test fixture ground strap to any heat-sink in this
instrument.
Electro-statically Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged easily by static electricity.
Such components are commonly called Electro-statically Sensitive (ES) Devices.
The typical examples of ES devices are integrated circuits, some field-effect transistors,
and semiconductor “chip” components. The following techniques should be used to help
reduce the incidence of component damage by static electricity.
1. Immediately before handling any semiconductor or semiconductor-equipped
assembly, wipe off any electrostatic charge on your body by touching any known
earth ground. Alternatively, obtain any commercially available discharging wrist
strap device which should be removed for potential shock reasons point to applying
power to the unit under testing conditions.
2. After removing the electrical assembly equipped with ES devices, place the assembly
on a conductive surface such as aluminum foil to prevent electrostatic charge buildup
or exposure to the assembly.
3. Only use a grounded-tip soldering iron to solder it unsolder ES device.
4. Only use an anti-static type solder removal device. Some solder removal devices not
classified as “anti-static” can generate enough electrical charges to damage ES
devices.
5. Do not use Freon-propelled chemicals. These can generate enough electrical charges
to damage ES devices.

EFFINET CONFIDENTIAL
EFFI-Service Manual R1.0 10
SERVICING PRECAUTIONS
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).
7. Immediately before removing the protective material from the leads of replacement
ES devices, touch the protective material to the chassis or circuit assembly into which
the device will be installed.
CAUTION : Be sure that no power is applied to the chassis or circuit, and observe
all other safety precautions.
8. Minimize bodily movements when handling unpackaged replacement Es devices.
(Otherwise harmful motion such as the brushing together clothes fabric or the lifting
your foot from a carpeted floor can generate enough static electricity to damage ES
devices).
General soldering Guidelines
1. Use a grounded-tip, low-wattage soldering iron with appropriate tip size and shape
that will maintain tip temperature between a 550˚F-660˚F(288˚C-316˚C)range.
2. Use an appropriate gauge of RMA resin-core solder composed of 60 parts tin/40 parts
lead.
3. Keep the soldering iron clean.
4. Clean the surface to be soldered. Use a small 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 soldering technique:
 Allow the soldering iron tip to reach normal temperature (550˚F to 660˚F or 288˚
C to 316˚C)
 Hold the soldering iron tip and solder strand against the component lead the
solder melts.
 Quickly move the soldering iron tip to the junction of the component lead and
the printed circuit foil, and hold it there until the solder flows onto and around
both the component lead and foil.
 Closely inspect the solder area and remove any excess or splashed solder with a
small wire-bristle brush.

SERVICING PRECAUTIONS
IC Removal/Replacement
Some utilized chassis circuit boards have slotted (oblong) holes through which the IC
leads are inserted and bent flat against the circuit foil. When holes are slotted, the
following technique should be used to remove and replace the IC.
Removal
1. De-solder and straighten each IC lead in one operation by gently prying up on the
lead with the soldering iron tip as the solder melts.
2. Draw away the melted solder with an anti-static suction-type solder removal
device(or with de-soldering 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 with a small wire-bristle brush. (It is not necessary to
reapply acrylic coating to the area)
“Small-signal” Discrete Transistor Removal / Replacement
1. Remove the defective transistor by clipping its leads as close as possible to
component body.
2. Bend the ends of each of three leads remaining on the circuit board into a “U” shape.
3. Bend the replacement transistor leads into a “U” shape.
4. Bend the replacement transistor leads to the corresponding leads extending from the
circuit board and crimp the “U” with long nose pliers to ensure metal-to-metal
contact, then solder each connection.
Power IC, Transistor or Devices Removal/Replacement
1. Heat and remove all solders from the device leads.
2. Remove the heat-sink mounting screw (if applicable).
3. Carefully remove the device from the circuit board and
4. Insert new device in circuit board.
5. Solder each device lead and then clip off excess lead.
