CAUTION FOR SAFETY IN PERFORMING REPAIR
1-1 LASER BEAM SAFETY PRECAUTIONS
This DVD player uses a pickup that emits a laser beam.
Do not look directly at the laser beam coming
from the pickup or allow it to strike against
your skin.
The laser beam is emitted from th e location shown in the figure. When checking the laser dio de, 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.

1-2 IMPORTANT SAFETY PRECAUTIONS
1-2-1 Product Safety Notice
Some electrical and mechanical parts have special
safety-related characteris tics which are often not evident from visual inspection, nor can the protection
they give necessarily b e obtained by replacing them
with components rated for higher voltage, wattage,
etc. Parts that have special safety characteri stics are
identified by a ! on schematics and in parts lists.
Use of a substitute replacement that does not have
the same safety characteristics as the recommended
replacement part might create shock, fire, and/or
other hazards. The Product’s Safety is under review
continuously and new instructions are issued whenever appropriate. Prior to shipment from the factory,
our products are carefully inspected to confirm with
the recognized prod uct safety and electr ical codes of
the countries in which they are to be sold. However, in
order to maintain such compliance, it is equally important to implement the following precautions when a
set is being serviced.
1-2-2 Precautions during Servicing
A. Parts identified by the ! symbol are critical for
safety. Replace only with part number specified.
B. In addition to safety, other parts and assemblies
are specified for conformance with regulations
applying to spur io us radiati on. T he se must a lso be
replaced only with specified re pla ce men ts.
Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking filters, etc.
C. Use specified internal wiring. Note especially:
1)Wires covered with PVC tubing
2)Double insulated wi res
3)High voltage leads
D. Use specified insulating materials for hazardous
live parts. Note especially:
1)Insulation tape
2)PVC tubing
3)Spacers
4)Insulators for transistors
E. When replacing AC primary side components
(transformers, power cord, etc.), wrap ends of
wires securely abo ut the terminals before soldering.
F. Observe that the wires do not contact heat produc-
ing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.).
G. Check that replaced wires do not contact sharp
edges or pointed parts.
H. When a power cord has been repl ace d, c he ck that
5 - 6 kg of force in any direction will not loosen it.
I. Also check areas surrounding repaired locations.
J. Be careful that foreign objects (screws, solder
droplets, etc.) do not remain inside the set.
K. Crimp type wire connector
The power transformer uses crimp type connectors which connect the power cord and the primary
side of the transformer. When replacing t he transformer, follow these steps carefully and precisely
to prevent shock hazards.
Replacement procedure
1)Remove the old connector by cutting the wires at
a point close to the connector.
Important: Do not re-use a connector. (Discard
it.)
2)Strip about 15 mm of the insul ation from the ends
of the wires. If the wires are stranded, twist the
strands to avoid frayed conductors.
3)Align the lengths of the wires to be connected.
Insert the wires fully into the connector.
4)Use a cri mping tool to crimp the metal sleeve at
its center. Be sure to crimp fully to the compl ete
closure of the tool.
L. When connecting or disconnecting the internal
connectors, first, disconnec t the AC plug from the
AC outlet.

1-2-3 Safety Check after Servicing
Examine the area surrounding the repaired location
for damage or deterioration. Observe that screws,
parts, and w ires have been returned to thei r original
positions. Afterwards, do the following tests and confirm the specified values to verify compliance with
safety standards.
1. Clearance Distance
When replacing pr imary circuit components, confir m
specified clearance di sta nc e ( d ) and ( d’ ) between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1-2-1)
Table 1-2-1 : Ratings for selected area
AC Line VoltageClearance Distance (d), (d’)
220 to 240 V
Note: This table is unofficial and for reference only.
Be sure to confirm the precise values.
≥3 mm(d)
≥6 mm(d’)
2. Leakage Current Test
Confirm the specified (or lower) leakage current
between B (earth ground, power cord plug prongs)
and externally exposed accessible parts (RF terminals, antenna terminals, video and audio input and
output terminals, microphone jacks, earphone jacks,
etc.) is lower than or equal to the specified value in the
table below.
Measuring Method (Power ON) :
Insert load Z between B (ear th ground, power cord
plug prongs) and exposed accessible par ts. Use an
AC voltmeter to measure across the terminal s of load
Z. See Fig. 1-2-2 and the following table.

Cautions On Batteries
Use “AA” (R6P) batteries in this remote control unit.
Replace the batteries with new ones approximately
once a year, though this depends on the frequency
with which the remote control unit is used.
If the remote control unit does not operate from
close to the main unit, replace the batteries with
new ones, even if less then a year has passed.
The included battery is only for verifying operation.
Replace it with a new battery as soon as possible.
When inserting the batteries, be careful to do so in
the proper direction, following the and marks
in the remote control unit’s battery compartment.
To prevent damage or battery fluid leakage:
Do not use a new battery with an old one.
Do not use two different types of batteries such
as alkaline and manganese.
Do not short-circuit, disassemble, heat or dispose
of batteries in flames.
Remove the batteries when not planning to use the
remote control unit for a long period of time.
If the batteries should leak, carefully wipe off the
fluid from the inside of the battery compartment,
then insert new batteries.

4-3 ALIGNMENT PROCEDURES OF MECHANISM
The following procedures describe how to align the
individual gears and levers that make up the tape
loading/unloading mechanism. Since information
about the state of the mechanism is provided to the
System Control Circ uit onl y through the Mode Switch,
it is essential that the correct relationship between
individual gears and levers be maintained.
All alignments are to be performed with the mech-
anism in Eject mode, in th e sequence given. Each
procedure assumes tha t al l pr evious pro ce dures have
been completed.
IMPORTANT:
If any one of these ali gnments i s not perfor med prop erly, even if off by only one tooth, the unit will unload
or stop and it may result in damage to the me chan ic al
or electrical parts.

CAUTION !
For continued protection against fire hazard,
replace only with the same type fuse.
NOTE :
The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
CAUTION !
Fixed voltage ( or Auto voltage selectable ) power supply circuit is used in this unit.
If Main Fuse (F1001) is blown, 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.

BECAUSE A HOT CHASSIS GROUND IS PRESENT IN THE POWER
SUPPLY CIRCUIT , AN ISOLATION TRANSFORMER MUST BE USED.
ALSO , IN ORDER TO HAVE THE ABILITY TO INCREASE THE INPUT
SLOWLY , WHEN TROUBLESHOOTING THIS TYPE POWER SUPPLY
CIRCUIT , A VARIABLE ISOLATION TRANSFORMER IS REQUIRED.
