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.

IMPORTANT SAFETY PRECAUTIONS
Product Safety Notice
Some electrical and mechanical parts have special
safety-related characteristics which are often not evi-
dent 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 substi-
tute 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 compli-
ance, 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 block-
ing 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, fus-
ible 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 con-
nectors, first, disconnect the AC plug from the AC
outlet.
1-3-1 DVD_SFN1

Safety Check after Servicing
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 speci-
fied values to verify compliance with safety standards.
1. Clearance Distance
When replacing primary circuit components, confirm
specified clearance distance (d) and (d’) between sol-
dered terminals, and between terminals and surround-
ing metallic parts. (See Fig. 1)
Table 1 : Ratings for selected area
AC Line Voltage Clearance Distance (d) (d’)
120 V ≥3.2 mm (0.126 inches)
Note: This table is unofficial and for reference only.
Be sure to confirm the precise values.
2. Leakage Current Test
Confirm the specified (or lower) leakage current be-
tween B (earth ground, power cord plug prongs) and
externally exposed accessible parts (RF terminals, an-
tenna terminals, video and audio input and output ter-
minals, 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.
Table 2 : Leakage current ratings for selected areas

How to Remove / Install Flat Pack-IC
1. Removal
With Hot-Air Flat Pack-IC Desoldering Machine:
(1)Prepare the hot-air flat pack-IC desoldering ma-
chine, then apply hot air to the Flat Pack-IC (about
5 to 6 seconds). (Fig. S-1-1)
(2)Remove the flat pack-IC with tweezers while apply-
ing the hot air.
(3)Bottom of the flat pack-IC is fixed with glue to the
CBA; when removing entire flat pack-IC, first apply
soldering iron to center of the flat pack-IC and heat
up. Then remove (glue will be melted). (Fig. S-1-6)
(4)Release the flat pack-IC from the CBA using tweez-
ers. (Fig. S-1-6)
Caution:
1.Do not supply hot air to the chip parts around the flat
pack-IC for over 6 seconds because damage to the
chip parts may occur. Put masking tape around the
flat pack-IC to protect other parts from damage.
(Fig. S-1-2)
2.The flat pack-IC on the CBA is affixed with glue, so
be careful not to break or damage the foil of each
pin or the solder lands under the IC when removing
it.

With Soldering Iron:
(1)Using desoldering braid, remove the solder from all
pins of the flat pack-IC. When you use solder flux
which is applied to all pins of the flat pack-IC, you
can remove it easily. (Fig. S-1-3)
(2)Lift each lead of the flat pack-IC upward one by one,
using a sharp pin or wire to which solder will not
adhere (iron wire). When heating the pins, use a fine
tip soldering iron or a hot air desoldering machine.
(Fig. S-1-4)
(3)Bottom of the flat pack-IC is fixed with glue to the
CBA; when removing entire flat pack-IC, first apply
soldering iron to center of the flat pack-IC and heat
up. Then remove (glue will be melted). (Fig. S-1-6)
(4)Release the flat pack-IC from the CBA using tweez-
ers. (Fig. S-1-6)
With Iron Wire:
(1)Using desoldering braid, remove the solder from all
pins of the flat pack-IC. When you use solder flux
which is applied to all pins of the flat pack-IC, you
can remove it easily. (Fig. S-1-3)
(2)Affix the wire to a workbench or solid mounting point,
as shown in Fig. S-1-5.
(3)While heating the pins using a fine tip soldering iron
or hot air blower, pull up the wire as the solder melts
so as to lift the IC leads from the CBA contact pads
as shown in Fig. S-1-5.
(4)Bottom of the flat pack-IC is fixed with glue to the
CBA; when removing entire flat pack-IC, first apply
soldering iron to center of the flat pack-IC and heat
up. Then remove (glue will be melted). (Fig. S-1-6)
(5)Release the flat pack-IC from the CBA using tweez-
ers. (Fig. S-1-6)
Note:
When using a soldering iron, care must be taken to
ensure that the flat pack-IC is not being held by glue.
When the flat pack-IC is removed from the CBA,
handle it gently because it may be damaged if force
is applied.

2. Installation
(1)Using desoldering braid, remove the solder from the
foil of each pin of the flat pack-IC on the CBA so you
can install a replacement flat pack-IC more easily.
(2)The " ●" mark on the flat pack-IC indicates pin 1.
(See Fig. S-1-7.) Be sure this mark matches the 1
on the PCB when positioning for installation. Then
pre- solder the four corners of the flat pack-IC. (See
Fig. S-1-8.)
(3)Solder all pins of the flat pack-IC. Be sure that none
of the pins have solder bridges.
Instructions for Handling
Semiconductors
Electrostatic breakdown of the semiconductors may
occur due to a potential difference caused by electro-
static 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 semiconductors are to be placed.
Because the static electricity charge on clothing will not
escape through the body grounding band, be careful to
avoid contacting semiconductors with your clothing.

SCHEMATIC DIAGRAMS / CBA’S AND TEST POINTS
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 replace-
ment components rated for higher voltage, wattage, etc.
Replacement parts that have these special safety char-
acteristics are identified in this manual and its supple-
ments; electrical components having such features are
identified by the mark " # " in the schematic diagram
and the parts list. Before replacing any of these compo-
nents, 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.
