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.
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
1M: and 5.2M:.
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 1.5k:,10watts 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
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 mu3st 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.
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, alminum 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.
3
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 to
damage an ES device).

6 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.
6.1. 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.
6.1.1. Worktable grounding
1. Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet.
6.1.2. Human body grounding
1. Use the anti-static wrist strap to discharge the static electricity form your body.
5.13.3. List of the Extention Cables
6.1.3. 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.
6.2. 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.

7 OPTICAL PICKUP SELF-DIAGNOSIS AND
REPLACEMENT PROCEDURE
7.1. Self-diagnosis
The optical pickup self-diagnosis function and tilt adjustment check function have been included in this unit. When repairing, use
the following procedure for effective Self-diagnosis and tilt adjustment.Be sure to use the self-diagnosis function before replacing
the optical pickup when "NO DISC" is displayed. As a guideline, you should replace the optical pickup when the value of the laser
drive current is more than 55.
Note:
Press the power button to turn on the power, and check the value within three minutes before the unit warms up. (Otherwise,
the result will be incorrect.)
12
7.2. Cautions to Be Used Before Replacing the Optical Pickup Unit and Spindle Motor Assembly
Before replacing the optical pickup unit and spindle motor assembly, check the total using hours for each of them. The checking
method is as follows:
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 ELECTRICITY DISCHARGE.)
1. Do not touch the areas around the laser diode and
actuator.
2. Do not judge the laser diode with a tester. (The tester
will be damaged easily.)
3. It is recommended to use a destaticized soldering iron
for short-circuiting or removing the laser diode.
(Recommended soldering iron) HAKKO ESD Product
4. Solder the land of the flexible cable in the optical pickup.
Note:
x
xWhen using a soldering iron which is not
xx
destaticized, short-circuit the terminal face of the
flexible case with a clip. After that, short-circuit
the land.
x
xAfter the repairing work is completed, remove the
xx
solder according to the correct procedure shown
in this Technical Guide.

8.3. Fault diagnosis using new self-diagnosis function
The 5th generation DVD players have the additional new service modes as described above to further reinforce the diagnosis
function.
These new functions are unable to bring sufficient results when they are used alone.
Effective fault diagnosis can be expected when multiple diagnostic methods are properly combined in accordance with the servicing
procedures depending on specific fault status.
* New servicing procedures are now under study to match with the newly developed self-diagnosis functions introduced here.
Details of the new servicing procedures will be informed from time to time.
1. Cumulative operation time display function
For spindle motor and DVD/CD laser, the cumulative operation time is displayed.
When servicing, check the timer display and use it as information for fault diagnosis.
At the time of repair and replacement of these components, make sure to check the operation time and reset the timer after
replacement.
Operation time of the replacement parts (spindle motor and laser) is the valuable information as actual data for future product
quality.
Please save the records and supply information to us.
2. Servo process display function
This additional function is intended to improve efficiency of fault diagnosis, especially for the player´s startup failure, in
combination with the learned value data of ADSC internal RAM.
3. ADSC internal RAM display function
The function is to display the internal RAM data of ADSC servo processor.
The RAM data are the learned values of drive servo, memorizing those concerning focus and tracking, as well as data slice and

2. How to utilize
At present, learned values of ADSC internal RAM are expected to be useful for the following faulty part identification.
Use how learned value changes from initial value to find whether faulty part exists before or after ADSC in the focus/tracking
servo system.
[Focus system]
When focus gain remains at initial value and tracking gain changes, fault exists before ADSC input.
When focus gain changes and tracking gain remains at initial value, fault exists after ADSC output.
[Tracking system]
When focus gain remains at initial value and tracking gain changes, fault exists after ADSC output.
When focus gain changes and tracking gain remains at initial value, fault exists before ADSC input.
