SECTION 1
Important Safety Precautions
1.1 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 shou ld
not be made. Any design alterations of the product should
not be made. Any design alterations or additions will vo id
the manufacturers 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 specia l
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 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.
1.2 Warning
1.3 Caution
Burrs formed during molding may be left over on some
parts of the chassis.
Therefore, pay attention to such burrs in the case of preforming repair of this system.
1.4 Critical parts for safety
In regard with component parts appearing on the silk-screen
printed side (parts side) of the PWB diagrams, the parts that are
printed over with black such as the resistor ( ), diode ( )
and ICP ( ) or identified by the " " mark nearby are critical
for safety.
When replacing them, be sure to use the parts of the same type
and rating as specified by the manufacturer. (Except the JC version)
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
mA AC (r.m.s.).

(1) This equipment has been designed and manufactured to
meet international safety standards.
(2) It is the legal responsibility of the repairer to en sure 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 re placed
by approved parts.
(5) If mains voltage selector is provided, check setting for lo-
cal voltage.

1.5 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.
1.5.1 Grounding to prevent damage by static electricity
Static electricity in the work area can destroy the optical pickup (laser dio de) in devices such as DVD players.
Be careful to use proper grounding in the area where repairs are being performed.
(1) Ground the workbench
Ground the workbench by laying conductive material (such as a conductive sheet) or an iron pl ate over it before placing the
traverse unit (optical pickup) on it.
(2) Ground yourself
Use an anti-static wrist strap to release any static electricity built up in your body.

(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 op-
tical 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.
1.6 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)I t is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it

1.8 Precautions for Service
1.8.1 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 precisi on 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 picku p, remove the solder on the short land wh ich 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.
1.8.2 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 th e workbench on whi ch the traverse unit or th e pick up is to be repaired, ground
the sheet or the plate.
(3) After removing the flexible wire fro m 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.
Please refer to "Fig.2-4" of "Disassembly
method" for details.

3.12.9 Neither picture nor sound is output
(1) It is not possible search
• Has the tracking been turned on?
• To "(5) Tracking ON NG" in "Check points for each error" when the tracking is not normal.
• Is the feed operation normal?
To "(3) traverse movement NG" in "Check points for each error" when it is not normal.
Are not there caught of the feeding mechanism etc?
3.12.10 Picture is distorted or abnormal sound occurs at intervals of several seconds.
Is the feed operation normal?
Are not there caught of the feeding mechanism etc?
3.12.11 Others
The image is sometimes blocked, and the image stops.
The image is blocked when going to outer though it is
normal in surroundings in the disk and the stopping
sympton increases.
3.12.12CD During normal playback operation
a) Is TOC reading normal?
Displays total time
for CD-DA.
Shifts to double-speed
mode for V-CD
There is a possibility with bad jitter
value for such a symptom.
XV-SA600BK/XV-SA602SL
b) Playback possible?
• --:-- is displa yed during FL search.
According to [It is not possible to search ] for DVD(9), check the feed
and tracking systems.
• No soun d is output althou gh the time is displayed.(CA-DA)
DAC, etc, other than servo.
• The passage of time is not stable, or picture is abnormal.(V-CD)
• The woun d of the disc and dirt are confirmed.
