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 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 product safety and electrical 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.
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 replacements.
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 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 replaced, check that
5 - 6 kg of force in any direction will not loosen it.
I. Also check areas surrounding repaired locations.
J. Use care that foreign objects (screws, solder drop-
lets, 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 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 the complete closure of the tool.
L. When connecting or disconnecting the internal
connectors, first, disconnect the AC plug from the
AC outlet.

Examine the area surrounding the repaired location for
damage or deterioration. Observe that screws, parts,
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 clearance distance (d) and (d’) between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)
T able 1 : Ratings for selected area
AC Line Voltage Clearance Distance (d) (d’)
110 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 (earth ground, power cord
plug prongs) and exposed accessible parts. Use an
AC voltmeter to measure across the terminals of load
Z. See Fig. 2 and the following table.

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.

Reference Notes
CAUTION 1: Locking Tabs (L-1) are fragile. Be careful
not to break them.
1-1. Remove Screw (S-2).
1-2. Disconnect connectors CN505 on the Main CBA
and CN2014 on the Tuner CBA.
1-3. Release seven Locking Tabs (L-1) (to do this,
first release five Locking Tabs (A) at the side and
top, and then release two Locking Tabs (B) at the
bottom.)
CAUTION 2: Do not disconnect connector CN201 until
the three short lands of FPC is shorted as shown in
Fig. D5. Refer to below.
CAUTION 3: Electrostatic breakdown of the laser
diode in the optical system block may occur as a
potential difference caused by electrostatic charge
accumulated on cloth, human body etc., during
unpacking or repair work.
To avoid damage of pickup follow next procedures.
3-1. Short the three short lands of FPC cable with sol-
der before removing the FFC cable (CN201) from
it. If you disconnect the FFC cable (CN201), the
laser diode of pickup will be destroyed. (Fig. D5)
3-2. Disconnect Connector (CN301) and lift the DVD
Main CBA Unit. (Fig. D5)
CAUTION 4: When reassembling, confirm the FFC
cable (CN301) is connected completely. Then remove
the solder from the three short lands of FPC cable.
(Fig. D5)
4. When reassembling, solder wire jumpers as shown
in Fig. D9.
5. Before installing the Deck Assembly, be sure to
place the pin of LD-SW on Main CBA as shown in
Fig. D9. Then, install the Deck Assembly while
aligning the hole of Cam Gear with the pin of LDSW, the shaft of Cam Gear with the hole of LD-SW
as shown in Fig. D9.
