IMPORTANT SAFETY PRECAUTIONS

Product Safety Notice

Some electrical and mechanical parts have special
safety-related characterist ic s whic h ar e 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 powe r cord ha s been re place d, chec k th at

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.

1-2-1 DVDN_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

Primary Circuit

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 Curre nt 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.

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-di git. Digit 2&3 shows the
WEEK, and digit 4 shows the YEAR.

So from onwards=from 1 Jan 2005 onwards

Important note: In fact also products of year 2004
must be treated in this way as long as you avoid
mixing solder-alloys (leaded/ lead- free) . So bes t 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 lead­free 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 Service­Manuals. Not listed standard-material (commodities)
has to be purchased at external companies.

- 380°C is reached and stabilized at the

1 Jan 2005

1-3-1 DVDN_PC_SN

• 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.

(about 5 to 6 seconds). (Fig. S-1-1)

Fig. S-1-1

2. Remove the flat pack-IC with tweezers while
applying 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
tweezers. (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 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)

1-3-2 DVDN_PC_SN

3. 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)

With Iron Wire:

1. Using desoldering brai d, 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
tweezers. (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
presolder 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.

Example :

Pin 1 of the Flat Pack-IC
is indicated by a " " mark.

Instructions for Handling Semi­conductors

Electrostatic breakdown of the semi-cond uc tors 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.
