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
producing parts (heat sinks, 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. Be careful that foreign objects (screws, solder
droplets, etc.) do not remain inside the set.
K. When connecting or disconnecting the internal
connectors, first, disconnect the AC plug from the
AC outlet.
1-2-1DVDN_ISP

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 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)
Table 1: Ratings for selected area
Chassis or Secondary Conductor
Primary Circuit
AC Line VoltageClearance 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
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.

Pb (Lead) Free Solder
When soldering, be sure to use the Pb free solder.
Information about lead-free soldering
Philips CE is producing lead-free sets from 1.1.2005
onwards.
IDENTIFICATION
Regardless of special logo (not always
indicated)
One must treat all sets from
onwards, according to the next rule:
Serial Number gives a 9-digit. Digit 2&3 shows the
WEEK, and digit 4 shows the YEAR.
So from onwards=from 1 Jan 2005 onwards
Important note
must be treated in this way as long as you avoid
mixing solder-alloys (leaded/ lead-free). So best to
always use SAC305 and the higher temperatures
belong to this.
Due to lead-free technology some rules have to be
respected by the workshop during a repair:
• Use only lead-free solder alloy Philips SAC305 with
order code 0622 149 00106. If lead-free solderpaste is required, please contact the manufacturer
of your solder-equipment. In general use of solderpaste within workshops should be avoided because
paste is not easy to store and to handle.
• Use only adequate solder tools applicable for lead-
free solder alloy. The solder tool must be able
• To reach at least a solder-temperature of 400°C,
• To stabilize the adjusted temperature at the solder-
• To exchange solder-tips for different applications.
• Adjust your solder tool so that a temperature around
360°C
solder joint. Heating-time of the solder-joint should
not exceed ~ 4 sec. Avoid temperatures above
400°C otherwise wear-out of tips will rise drastically
and flux-fluid will be destroyed. To avoid wear-out of
tips switch off un-used equipment, or reduce heat.
• Mix of lead-free solder alloy / parts with leaded
solder alloy / parts is possible but PHILIPS
recommends strongly to avoid mixed solder alloy
types (leaded and lead-free).
If one cannot avoid or does not know whether
product is lead-free, clean carefully the solder-joint
from old solder alloy and re-solder with new solder
alloy (SAC305).
• Use only original spare-parts listed in the Service-
Manuals. Not listed standard-material (commodities)
has to be purchased at external companies.

: In fact also products of year 2004
tip
- 380°C is reached and stabilized at the
1 Jan 2005
1-3-1DVDN_PC_SN
Page 7
• Special information for BGA-ICs:
- always use the 12nc-recognizable soldering
temperature profile of the specific BGA (for desoldering always use the lead-free temperature
profile, in case of doubt)
- lead free BGA-ICs will be delivered in so-called
'dry-packaging' (sealed pack including a silica gel
pack) to protect the IC against moisture. After
opening, dependent of MSL-level seen on indicatorlabel in the bag, the BGA-IC possibly still has to be
baked dry. (MSL=Moisture Sensitivity Level). This
will be communicated via AYS-website.
Do not re-use BGAs at all.
• For sets produced before 1.1.2005 (except products
of 2004), containing leaded solder-alloy and
components, all needed spare-parts will be available
till the end of the service-period. For repair of such
sets nothing changes.
• On our website

Instructions for Handling Semiconductors
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 (1 MΩ) 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 (1 MΩ) 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.

1. CAUTION 1: Locking Tabs (L-1) and (L-2) are
fragile. Be careful not to break them.
1) Release three Locking Tabs (L-1).
2) Release three Locking Tabs (L-2), then remove
the Front Assembly.
2. CAUTION 2: 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.
1) Disconnect Connector (CN301). Remove
Screws (S-6) and lift the DVD Main CBA Unit.
(Fig. D4)
2) Short the three short lands of FPC cable with
solder before removing the FFC cable (CN201)
from it. If you disconnect the FFC cable
(CN201), the laser diode of pickup will be
destroyed. (Fig. D4)
3. CAUTION 3: When reassembling, confirm the
FFC cable (CN201) is connected completely. Then
remove the solder from the three short lands of
FPC cable. (Fig. D4)
4. When reassembling, solder wire jumpers as
shown in Fig. D6.
5. Before installing the Deck Assembly, be sure to
place the pin of LD-SW on Main CBA as shown in
Fig. D6. 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. D6.

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
replacement components rated for higher voltage,
wattage, etc. Replacement parts that have these
special safety characteristics are identified in this
manual and its supplements; electrical 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 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.

NOTE:
The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
Because a hot chassis ground is present in the power
supply circut, an isolation transformer must be used.
Also, in order to have the ability to increase the input
slowly, when troubleshooting this type power supply
circuit, a variable isolation transformer is required.
