LASER BEAM SAFETY PRECA UTIONS

This DVD player uses a pickup that emits a laser beam.

The laser beam is e mitted from the l ocation shown in th e figure. When checking th e laser diode, be sur e to keep
your eyes at least 30cm away from the pickup lens when the diode is t urned on. D o not look directl y at the laser
beam.

Caution: Use of controls and a djustments, or doing proc edures other than those s pecified herein, may result i n
hazardous radiation exposure.

Do not look directly at the l aser beam coming
from the pickup or allo w it t o stri ke a gains t your
skin.

IMPORTANT SAFETY PRECAUTIONS

Product Safe t y 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 characteri stic s are ide n­tified 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 haz ­ards. 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 produ ct safety and electrical co des of
the countries in which they are to be sold. However, in
order to maintain such com plian ce, it is eq ually 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 spu riou s radiation . These must al so be
replaced only with specified replacements.
Examples: RF converters, RF ca bles, 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 wi res do no t contact heat produc-

ing parts (heat sink s, oxide metal film resisto rs, fus­ible resistors, etc.).

G. Check that replaced wires do not contact sharp

edges or pointed parts.

H. When a power cord h as been replaced , check tha t

5 - 6 kg of force in any direction will not loosen it.

I. Also check areas surrounding repa ir 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 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 m m of the insulat ion 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, dis connect the AC plug from the
AC outlet.

Safety Check after Servicing

Examine the area surrounding the repaired location for
damage or deter ioration. 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’) between so l­dered terminals, and between terminals and surround­ing metallic parts. (See Fig. 1)

Table 1 : Ratings for selected area

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
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 ter minals of load
Z. See Fig. 2 and the following table.

STANDARD NOTES FOR SERVICING

Circuit Board Indications

1. The output pin of th e 3 pin Regulator ICs is indi­cated as shown .

2. For other ICs, pin 1 and every fifth pin are indicated
as shown.

3. The 1st pin of every male connector is indicate d as
shown.

Instructions for Connectors

1. When you connec t or di scon nect the FFC (Flexible
Foil Connector) cable, be sure to first disconnect
the AC cord.

2. FFC (Flexible Foil Connector) cable should be
inserted parallel into the connector, not at an angle.

Pb (Lead) Free Solder

When soldering, be sure to use the Pb free solder.

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

machine, 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 iro n to center of the flat pack-IC and he at
up. Then remove (glue will be melted). (Fig. S-1-6)

(4) Release the flat pack-IC from the CBA usi ng twee-

zers. (Fig. S-1-6)

Caution:

1. The Flat Pack-IC shape may differ by models. Use
an appropriate hot-air flat pack-IC desoldering
machine, whose shape matches that of the Flat
Pack-IC.

2. Do not supply ho t air to the chip parts a round 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.

3. The flat pack-IC on the CBA is affixed with glue, so
be careful not to brea k 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 th e 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 shar p pin or wire to which solde r will
not adhere (iron wire). When heatin g 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 iro n to center of the flat pack-IC and he at
up. Then remove (glue will be melted). (Fig. S-1-6)

(4) Release the flat pack-IC from the CBA usi ng twee-

zers. (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 th e 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

up. Then remove (glue will be melted). (Fig. S-1-6)

(5)Release the flat pack-IC from the CBA usin g twee-

zers. (Fig. S-1-6)

Note:

When using a solder ing iron, care must be taken
to ensure that the flat pack-IC is not being h eld by
glue. When the flat pack-IC is removed from the
CBA, handle it gently beca use 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 “I” mark on the flat pack-IC in dicates pin 1.

(See Fig. S-1-7.) Be sure this ma rk matches the 1
on the PCB when positio ning for installation. Then
presolder the four cor ners of t he 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.
