1.1.1. LEAKAGE CURRENT COLD
CHECK
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 the chassis, the reading should be between
1MΩand 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)
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
capacitor, between each exposed metallic part on the set
and a good earth ground such as a water pipe, as shown in
Figure 1.
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.
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 must not exceed 1/2 milliamp. In case a
measurement is outside of 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.
1 SAFETY PRECAUTIONS
1.1. GENERAL GUIDELINES
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.

2 PREVENTION OF ELECTRO STATIC DISCHARGE (ESD)
TO 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 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 discharging ESD 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, aluminium foil or
comparable conductive 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 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 (ESD)
sufficient to damage an ES device).

3 Precaution of Laser Diode
3.1. About lead free solder (PbF)
This model uses lead free solder (PbF). For repair use only lead free handsolder.
Caution:
Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please
use a high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700 +/-20°F (370
+/-10°C). Pb free solder will tend to splash when heated too high (about 1100°F/ 600°C). When soldering or unsoldering, please
completely remove all of the solder on the pins or solder area and be sure to heat the soldering points with the Pb free solder
until it melts enough.

5 PREVENTION OF STATIC ELECTRICITY DISCHARGE
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
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
1.Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet.
5.1.2. Human body grounding
1.Use the anti-static wrist strap to discharge the static electricity form your body.
5.1.3. Handling of optical pickup
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 according to 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.
5.2. Handling Precautions for Traverse Unit (Optical Pickup)
1.Do not give a considerable shock to the traverse unit (optical pickup) as it has an extremely high-precise 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 preventing static
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.

DVD-S35E / DVD-S35EB / DVD-S35EG / DVD-S31EG

Cautions to be taken when replacing the optical pickup
The optical pickup may break down due to the static
electricity of human body. Take proper protection measures
against static electricity before repairing the parts around
the optical pickup. (See the page describing the
PREVENTION OF STATIC ELECTRICITYDISCHARGE.)
1.Do not touch the areas around the laser diode and
actuator.
2.Do not judge the laser diode with a tester. (The tester
