1.1 GENERAL GUIDELINES
TOP PREVIOUS NEXT
1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which
have been overheated or damaged by the short circuit.
2. After servicing, see to it that all the protective devices such as insulation barriers, insulation
papers shields are properly installed.
3. After servicing, make the following leakage current checks to prevent the customer from being
exposed to shock hazards.
1.1.1 LEAKAGE CURRENT COLD CHECK
1.1.2 LEAKAGE CURRENT HOT CHECK (See Figure 1 .)
TOP PREVIOUS NEXT
1.1.1 LEAKAGE CURRENT COLD CHECK
TOP PREVIOUS NEXT
1. Unplug the AC cord and connect a jumper between the two prongs on the plug.
2. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each
exposed metallic cabinet part on the equipment such as screwheads, connectors, control shafts,
etc. When the exposed metallic part has a return path to thechassis, the reading should be
between 1MΩ and 5.2MΩ.
When the exposed metal does not have a return path to the chassis, the reading must be
.
Figure 1

1.1.2 LEAKAGE CURRENT HOT CHECK (See
Figure 1 .)
TOP PREVIOUS NEXT
1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check.
2. Connect a 1.5kΩ, 10 watts resistor, in parallel with a 0.15μF capacitors, between each exposed
metallic part on the set and a good earth ground such as a water pipe, as shown in
3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across
the resistor.
4. Check each exposed metallic part, and measure the voltage at each point.
5. Reverse the AC plug in the AC outlet and repeat each of the above measurements.
Figure 1 .
6. The potential at any point should not exceed 0.75 volts RMS. A leakage current tester (Simpson
Model 229 or equivalent) may be used to make the hot checks, leakage current mu3st not exceed
1/2 milliamp. In case a measurement is outsideof the limits specified, there is a possibility of a
shock hazard, and the equipment should be repaired and rechecked before it is returned to the
customer.

2 PREVENTION OF ELECTRO STATIC
DISCHARGE (ESD) TO ELECTROSTATICALLY
SENSITIVE (ES) DEVICES
TOP PREVIOUS NEXT
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 transistorsand semiconductor "chip" components. The following
techniques should be used to help reduce the incidence of component damage caused by electro static
discharge (ESD).
1. Immediately before handling any semiconductor component or semiconductor-equipped
assembly, drain off any ESD on your body by touching a known earth ground. Alternatively,
obtain and wear a commercially available dischargingESD wrist strap, 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 alminum 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 solder removal device. Some solder removal devices not classified as
"anti-static (ESD protected)" can generate electrical charge 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, alminum foil or comparableconductive material).
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
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
hamless motion such as the brushing together of your clothes fabric or the lifting of your foot
from a carpeted floor can generate static electricity (ESD) sufficient todamage an ES device).

The laser diode in the traverse unit (optical pickup) may brake down due to static electricity of clothes or
human body. Use due caution to electrostatic breakdown when servicing and handling the laser diode.

5.1 Grounding for electrostatic breakdown
prevention
TOP PREVIOUS NEXT
Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be
damaged by static electricity in the working environment. Proceed servicing works under the working
environment where grounding works is completed.
5.1.1 Worktable grounding
5.1.2 Human body grounding
5.1.3 Handling of optical pickup
TOP PREVIOUS NEXT
5.1.1 Worktable grounding
TOP PREVIOUS NEXT
1. Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed, and
ground the sheet.
TOP PREVIOUS NEXT
5.1.2 Human body grounding
TOP PREVIOUS NEXT
1. Use the anti-static wrist strap to discharge the static electricity form your body.
TOP PREVIOUS NEXT
5.1.3 Handling of optical pickup
TOP PREVIOUS NEXT
1. To keep the good quality of the optical pickup maintenance parts during transportation and before
installation, the both ends of the laser diode are short-circuited. After replacing the parts with
new ones, remove the short circuit accordingto the correct procedure. (See this Technical Guide.)
2. Do not use a tester to check the laser diode for the optical pickup. Failure to do so will damage
the laser diode due to the power supply in the tester.
TOP PREVIOUS NEXT
5.2 Handling Precautions for Traverse Unit
(Optical Pickup)
TOP PREVIOUS NEXT
1. Do not give a considerable shock to the traverse unit (optical pickup) as it has an extremely highprecise structure.
2. When replacing the optical pickup, install the flexible cable and cut its short land with a nipper.
See the optical pickup replacement procedure in this Technical Guide. Before replacing the
traverse unit, remove the short pin for preventingstatic electricity and install a new unit. Connect
the connector as short times as possible.
3. The flexible cable may be cut off if an excessive force is applied to it. Use caution when handling
the cable.
4. The half-fixed resistor for laser power adjustment cannot be adjusted. Do not turn the resistor.
