Safety Precautions
1. This design of this product contains special hardware and many circuits and components specially
for safety purposes. For continued protection, no changes should be made to the original design
unless authorized in writing by the manufacturer. Replacement parts must be identical to those
used in the original circuits. Services should be performed by qualified personnel only.
2. Alterations of the design or circuitry of the product should not be made. Any design alterations of
the product should not be made. Any design alterations or additions will void the warranty
and will further relieve the manufacture of responsibility for personal injury or property damage
resulting therefrom.
3. Many electrical and mechanical parts in the products have special safety-related characteristics.
These characteristics are often not evident from visual inspection nor can the protection afforded
by them necessarily be obtained by using replacement components rated for higher voltage,
wattage, etc. Replacement parts which have these special safety characteristics are identified in
the Parts List of Service Manual. Electrical components having such features are identified by
shading on the schematics and by ( ) on the Parts List in the Service Manual. The use of a
substitute replacement which does not have the same safety characteristics as the recommended
replacement parts shown in the Parts List of Service Manual may create shock, fire, or other
hazards.
4. The leads in the products are routed and dressed with ties, clamps, tubings, barriers and the
like to be separated from live parts, high temperature parts, moving parts and/or sharp edges
for the prevention of electric shock and fire hazard. When service is required, the original lead
routing and dress should be observed, and it should be confirmed that they have been returned
to normal, after reassembling.
5. Leakage current check (Electrical shock hazard testing)
After reassembling the product, always perform an isolation check on the exposed metal parts of
the product (antenna terminals, knobs, metal cabinet, screw heads, headphone jack, control
shafts, etc.) to be sure the product is safe to operate without danger of electrical shock.
Do not use a line isolation transformer during this check.
Plug the AC line cord directly into the AC outlet. Using a "Leakage Current Tester", measure
the leakage current from each exposed metal parts of the cabinet , particularly any exposed
metal part having a return path to the chassis, to a known good earth ground. Any leakage
current must not exceed 0.5mA AC (r.m.s.)
Alternate check method
Plug the AC line cord directly into the AC outlet. Use an AC voltmeter having, 1,000 ohms
per volt or more sensitivity in the following manner. Connect a 1,500 10W resistor paralleled by
a 0.15 F AC-type capacitor between an exposed
metal part and a known good earth ground.
Measure the AC voltage across the resistor with the
AC voltmeter.
Move the resistor connection to each exposed
metal part, particularly any exposed metal part
having a return path to the chassis, and measure
the AC voltage across the resistor. Now, reverse
the plug in the AC outlet and repeat each
measurement. voltage measured Any must not
exceed 0.75 V AC (r.m.s.). This corresponds to 0.5
Warning
1. This equipment has been designed and manufactured to meet international safety standards.
2. It is the legal responsibility of the repairer to ensure that these safety standards are maintained.
3. Repairs must be made in accordance with the relevant safety standards.
4. It is essential that safety critical components are replaced by approved parts.
5. If mains voltage selector is provided, check setting for local voltage.

Preventing static electricity
Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged,
can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.
1.1. Grounding to prevent damage by static electricity
Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as DVD players.
Be careful to use proper grounding in the area where repairs are being performed.
1.1.1. Ground the workbench
1. Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over
it before placing the traverse unit (optical pickup) on it.
1.1.2. Ground yourself
1. Use an anti-static wrist strap to release any static electricity built up in your body.
1.1.3. Handling the optical pickup
1. In order to maintain quality during transport and before installation, both sides of the laser diode on the
replacement optical pickup are shorted. After replacement, return the shorted parts to their original condition.
(Refer to the text.)
2. Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power
source can easily destroy the laser diode.
1.2. Handling the traverse unit (optical pickup)
1. Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit.
2. Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific
details, refer to the replacement procedure in the text. Remove the anti-static pin when replacing the traverse
unit. Be careful not to take too long a time when attaching it to the connector.
3. Handle the flexible cable carefully as it may break when subjected to strong force.
4. It is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it

Precautions for Service
Handling of Traverse Unit and Laser Pickup
1. Do not touch any peripheral element of the pickup or the actuator.
2. The traverse unit and the pickup are precision devices and therefore must not be subjected to
strong shock.
3. Do not use a tester to examine the laser diode. (The diode can easily be destroyed by the
internal power supply of the tester.)
4. To replace the traverse unit, pull out the metal short pin for protection from charging.
5. When replacing the pickup, after mounting a new pickup, remove the solder on the short land
which is provided at the center of the flexible wire to open the circuit.
6. Half-fixed resistors for laser power adjustment are adjusted in pairs at shipment to match the
characteristics of the optical block.
Do not change the setting of these half-fixed resistors for laser power adjustment.
Destruction of Traverse Unit and Laser Pickup by Static Electricity
Laser diodes are easily destroyed by static electricity charged on clothing
or the human body. Before repairing peripheral elements of the traverse
unit or pickup, be sure to take the following electrostatic protection:
1. Wear an antistatic wrist wrap.
2. With a conductive sheet or a steel plate on the workbench on which
the traverse unit or the pick up is to be repaired, ground the sheet
or the plate.
3. After removing the flexible wire from the connector (CN101),
short-circuit the flexible wire by the metal clip.
4. Short-circuit the laser diode by soldering the land which is provided
at the center of the flexible wire for the pickup.
After completing the repair, remove the solder
to open the circuit.

correct?
Is the traverse moving
along the innermost
perimeter for SW detection?
"NO DISC" message appears
immediately after vertical
movement of the pick-up lens
The state that DISC does not rotate continues for
several seconds, and becomes NO DISC or an
error display afterwards.
The rotation of DISC becomes high-speed and
abnormal, and becomes NO DISC or an error
display afterwards.
Is focus retraction OK?
Even when it retracts
correctly, if it is out of focus
and makes repeated retries
with a clicking sound, it is
in error.
Is tracking retraction OK?
If TE waveform reappears
or fails to converge after the
TE retraction, it is in error.
Is the spindle servo
locked correctly?
Is the RF OUT waveform
locked correctly?
