IMPORTANT SAFETY NOTICE

Proper service and repair is important to the safe, reliable operation of all
Philips Consumer Electronics Com pany** Equipment. The service pr ocedures
recommended by Philips and described in this service manual are effective
methods of performing service operations. Some of these service operations
require the use of tools specially designed for the purpose. The special tools
should be used when and as recommended.

It is important to note that this manual contains various CAUTIONS and
NOTICES which should be carefully read in order to minimize the risk of per­sonal injury to service personnel. The possibility exists that improper service
methods may damage the equipment. It also is important to understand that
these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE. Philips could not
possibly know, evaluate and advise the service trade of all conceivable ways
in which service might be done or of the possible hazardous consequences of
each way. Consequently, Philips has not undertaken any such broad evalua­tion. Accordingly, a servicer who uses a service procedure or tool which is
not recommended by Philips must first satisfy himself thoroughly that neither
his safety nor the safe operation of the equipment will be jeopardized by the
service method selected.

** Hereafter throughout this manual, Philips Consumer Electronics Company

will be referred to as Philips.

WARNING

Critical components having special safety characteristics are identified
with a # by the Ref. No. in the parts list and enclosed within a broken
line* (where several critical components are grouped in one area) along
with the safety symbol # on the schematics or exploded views.

Use of substitute replacement parts which do not have the same specifie d
safety characteristics may create shock, fire, or other hazards.

Under no circumstances should the original design be modified or altered
without written permission from Philips. Philips assumes no liability,
express or implied, arising out of any unauthorized modification of
design. Servicer assumes all liability.

LASER BEAM SAFETY PRECAUTIONS

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

Do not look directly at the l aser beam coming
from the pickup or allo w it t o str ike agai nst your
skin.

The laser beam is emitted from the locatio n shown in the figure. When ch ecking the laser d iode, be sure to keep
your eyes at least 30cm away from the pickup lens when the diode is tur ned on. Do not loo k directly at the laser
beam.

Caution: Use of controls an d adjustments, or doing pr ocedures other than th ose specified here in, may result in
hazardous radiation exposure.

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 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 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.

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)

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.

(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 fla t pack-IC more
easily.

(2) The “I” mark on the flat pack-IC indicates pin 1.

(See Fig. S-1-7.) Be s ure this mark matches the 1
on the PCB when positioni ng for installation. Then
presolder the four cor ners of the fl at 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.

Example :

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

(4) 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.
