LASER BEAM SAFETY PRECAUTIONS
This DVD player uses a pickup that emits a laser beam.
The laser beam is emitted from the location shown in the figure. When checking the laser diode, be sure to keep your eyes at least
30cm away from the pickup lens when the diode is turned on. Do not look directly at the laser beam.
Caution: Use of controls and adjustments, or doing procedures other than those specified herein, may result in hazardous radiation
exposure.
Do not look directly at the laser beam coming
from the pickup or allow it to strike against
your skin.

BEFORE RETURNING THE DVD VIDEO PLAYER
Before returning the DVD video player to the user,
perform the following safety checks.
1. Inspect all lead dress to make certain that leads are
not pinched or that hardware is not lodged between
the chassis and other metal parts in the DVD video
player.
2. Inspect all protective devices such as non-metallic
control knobs, insulation materials, cabinet backs,
adjustment and compartment covers or shields,
isola-tion resistor/capacitor networks, mechanical
insula-tors etc.
3. To be sure that no shock hazard exists, check for
current in the following manner.
●Plug the AC line cord directly into a 230 volt AC outlet
(Do not use an isolation transformer for this test).
●Using two clip leads, connect a 1.5k ohm, 10 watt
resistor paralleled by a 0.15µF capacitor in series with
all exposed metal cabinet parts and a known earth
ground, such as a water pipe or conduit.
●Use an DVM or VOM with 1000 ohm per volt, or higher,
sensitivity or measure the AC voltage drop across the
resistor (See Diagram).
●Move the resistor connection to earth exposed metal
part having a return path to the chassis (metal cabinet,
screw heads, knobs and control shafts, etc.) and
measure the AC voltage drop across the resistor.
Reverse the AC plug on the set and repeat AC voltage
measurements for each exposed part. Any reading of
1.4V rms (this corresponds to 0.7mA rms AC.) or more
is excessive and indicates a potential shock hazard
which must be corrected before returning the DVD
video player to the owner.
AVANT DE RENDRE LE REPRODUCTOR DE VÍDEO
DVD
Avant de rendre le reproductor de vídeo DVD à l'utilisateur,
effectuer les vérifications de sécurité suivantes.
1. Vérifier toutes les gaines de fil pour être sûr que les fils
ne sont pas pincés ou que le matériel n'est pas coincé
entre le châssis et les autres pièces métalliques dans le
reproductor de vídeo DVD.
2. Vérifier tous les dispositifs de protection tels que les
boutons de commande non métalliques, les matériaux
d'isolement, le dos du coffret, les couvercles de
compartiment et ajustement ou les boucliers, les
réseaux de résistance / condensateur d'isolement, Ies
isolateurs mécaniques, etc.
3. Pour être sûr qu'il n'y a aucun risque de choc électrique,
vérifier le courant de fuite de la maniére suivante.
●Brancher le cordon d'alimentation secteur directement
dans une prise de courant de 230 volts. (Ne pas utiliser
de transformateur d'isolement pour cet essai).
●Utiliser deux fils à pinces et connecter une résistance de
10 watts 1,5 kohm en parallèle avec un condensateur
de 0,15 F en série avec des pièces du coffret métallique
exposées et une masse de terre connue telle qu'un
tuyau ou un conduit d'eau.
●Utiliser un DVM ou VOM avec une sensibilité de 1000
ohms par volt ou plus ou mesurer la chute de tension
CA entre la résistance (voir diagramme).
●Déposer la connexion de la résistance à toutes les de
pièces métalliques exposées ayant un parcours de
retour au châssis (coffret métallique, tétes de vis,
boutons et arbres de commande, etc.) et mesurer la
chute de tension CA entre la résistance. Inverser la
fiche CA (une fiche intermédiaire non polarisée doit être
utilisée à seule fin de faire ces vérifications.) sur
l’appareil et répéter les mesures de tension CA pour
chaque piéce métallique exposée. Toute lecture de 1,4
V rms (ceci correspond à 0,7 mA rms CA) ou plus est
excessive et signale un danger de choc qui doit être
corrigé avant de rendre le reproductor de vídeo DVD à
son utilisateur.

* Be careful to avoid a short circuit.
Using lead-free wire solder
When fixing the PWB soldered with the lead-free solder,
apply lead-free wire solder. Repairing with conventional
lead wire solder may cause damage or accident due to
cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is
higher than the lead wire solder by 40°C, we recommend
you to use a dedicated soldering bit, if you are not
familiar with how to obtain lead-free wire solder or
soldening bit, contact our service station or service
ranch in your area.
Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is
about 220°C which is higher than the conventional lead
solder by 40°C, and as it has poor solder wettabillty, you
may be apt to keep the soldering bit in contact with the
PWB for extended period of time. However, Since the
land may be peeled off or the maximum heat-resistance
temperature of parts may be excoeded, remove the bit
from the PWB as soon as you conurm the steady
soldering condition.
Lead-free solder contains more tin, and the end of the
soldering bit may be easily corroded. Make sure to tum
on and off the power of the bit as required. if a different
type of solder stays on the tip of the soldering bit, it is
alloyed with lead-free solder. Clean the bit after every
use of it.
When the tip of the soldering bit is blackened during
use, file it with steel wool or fine sandpaper.
Becareful when replacing parts with polarity indication
on the PWB silk.

Instructions for Handling
Semi-conductors
Electrostatic breakdown of the semi-conductors may
occur due to a potential difference caused by electrostatic
charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1MΩ) that is properly
grounded to remove any static electricity that may be
charged on the body.
2. Ground for Workbench
Be sure to place a conductive sheet or copper plate with
proper grounding (1MΩ) on the workbench or other
surface, where the semi-conductors are to be placed.
Because the static electricity charge on clothing will not
escape through the body grounding band, be careful to
avoid contacting semi-conductors with your clothing.

Standard Notes
WARNING
Many electrical and mechanical parts in this chassis
have special characteristics. These characteristics often
pass unnoticed and the protection afforded by them
cannot necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc.
Replacement parts that have these special safety
characteristics are identified in this manual and its
supplements; electrical components having such
features are identified by the mark " " in the schematic
diagram and the parts list. Before replacing any of these
components, read the parts list in this manual carefully.
The use of substitute replacement parts that do not
have the same safety characteristics as specified in the
parts list may create shock, fire, or other hazards.

Capacitors and transistors are represented by the
following symbols.
Notes:
1. Do not use the part number shown on these draw-
ings for ordering. The correct part number is shown
in the parts list, and may be slightly different or
amended since these drawings were prepared.
2. All resistance values are indicated in ohms (K=103,
M=106).
3. Resistor wattages are 1/4W or 1/6W unless other-
wise specified.
4. All capacitance values are indicated in µF
(P=10-6 µF).
5. All voltages are DC voltages unless otherwise speci-
fied.
6. Electrical parts such as capacitors, connectors, di-
odes, IC's, transistors, resistors, switches, and fuses
are identified by four digits. The first two digits are
not shown for each component. In each block of the
diagram, there is a note such as shown below to
indicate these abbreviated two digits.

LIST OF CAUTION, NOTES, AND SYMBOLS USED IN THE SCHEMATIC
DIAGRAMS ON THE FOLLOWING PAGES:
1.CAUTION:
FOR CONTINUED PROTECTION AGAINST FIRE HAZARD, REPLACE ONLY WITH THE
SAME TYPE FUSE.
2.CAUTION:
Fixed Voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F1001) is blown, first check to see that all components in the power supply circuit are not defective
before you connect the AC plug to the AC power supply. Otherwise it may cause some components in the power
supply circuit to fail.
3.Note:
(1)Do not use the part number shown on the drawings for ordering. The correct part number is shown in the parts list,
and may be slightly different or amended since the drawings were prepared.
(2)To maintain original function and reliability of repaired units, use only original replacement parts which are listed
with their part numbers in the parts list section of the service manual.
