IMPORTANT SAFETY PRECAUTIONS
Product Safety Notice
Some electrical and mechanical parts have special
safety-related characteristics which are often not evident from visual inspection, nor can the protection they
give necessarily be obtained by replacing them with
components rated for higher voltage, wattage, etc.
Parts that have special safety characteristics 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 par t might create shock, fire, and/or other h azards. 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 product safety and electrical codes of
the countries in which they are to be sold. However, in
order to maintain such compli ance, it is equall y impor tant to implement the following precautions when a set
is being serviced.
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 spurious radiation. These must also 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 wires
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 about the terminals before soldering.
F. Observe that the wires do not conta ct heat produc -
ing parts (heats inks, oxide metal fil m resis tors, fusible resistors, etc.).
G. Check that replaced wires do not contact sharp
edges or pointed parts.
H. When a power cord has been replaced, check that
5 - 6 kg of force in any direction will not loosen it.
I. Also check areas surrounding repair ed loc at ion s.
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 cri mp type con nector s
which connect the power cord and the primary side
of the transformer. When replacing the 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 insulation 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 crimping tool to crimp the metal sleeve at its
center. Be sure to crimp fully to t he complete closure of the tool.
L. When connecting or disconnecting the internal
connectors, first, disc onnect the AC plug from the
AC outlet.
1-3-1 DVD_SFNP
Safety Check afte r Servicing
Examine the area surrounding the repaired location for
damage or deteri oration. Observe that screws, par ts,
and wires have been returned to their original positions. Afterwards, do the following tests and confirm
the specified values to verify compliance with safety
standards.
1. Clearance Distance
When replacing primary circuit components, confirm
specified clearanc e distance (d ) and (d’) be tween soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)

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 (earth ground, power cord

Instructions for Handling
Semi-conductors
Electrostatic breakdown of the semi-conductors may
occur due to a potential di fference caused by electrostatic charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a groun ding band (1M Ω) that is properly grounded to re move any static electr ici ty that may
be charged on the body.
2. Ground for Workbench
(1) 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 thr ough the body grounding band, be careful t o avoid contacting semi-conductors with your clothing.

WARNING
Many electrical and m echanical 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 par ts that have these specia l safety
characteristics are identified in this manual and its
supplements; electr ical 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 par ts list in this manual
carefully. The use of substitut e replacem ent par ts that
do not have the same safety characteristics as specified in the parts list may create shock, fire, or other
hazards.
Notes:
1. Do not use the part number shown on these drawings 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
3
(K=10
3. Re sistor wattages are 1/4W or 1/6W unless otherwise specified.
4. All capacitance values are indicated in µF
(P=10
5. All voltages are DC voltages unless otherwise
specified.
6. Electrical parts such as capacitors, connectors,
diodes, 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 U SED 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 th at all compon ents in the power supply circ uit are not defective before you connect the AC plug to the AC power supply. Otherw ise it m ay cause some co mpo nents 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.
4. Wire Connectors
(1) Prefix symbol "CN" means "connector" (can disconnect and reconnect).
(2) Prefix symbol "CL" means "wire-solder holes of the PCB" (wire is soldered directly).
5. Voltage indications for PLAY and REC modes on the schematics are as shown below:
