Safety instruction
1. General safety
Safety regulations require that during a repair:
. Connect the unit to the mains via an isolation transformer.
. Replace safety components indicated by the symbol ,
only by components identical to the original ones. Any
other component substitution (other than original type)
may increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, you must
return the unit in its original condition. Pay, in particular,
attention to the following points:
. Route the wires/cables correctly, and fix them with the
mounted cable clamps.
. Check the insulation of the mains lead for external
damage.
. Check the electrical DC resistance between the mains
plug and the secondary side:
1) Unplug the mains cord, and connect a wire between
the two pins of the mains plug.
2) Set the mains switch the “on” position (keep the
mains cord unplug).
3) Measure the resistance value between the mains
plug and the front panel, controls, and chassis
bottom.
4) Repair or correct unit when the resistance
measurement is less than 1M
¡
.
5) Verify this, before you return the unit to the
customer/user (ref. UL-standard no. 1492).
6) Switch the unit “off”, and remove the wire between
the two pins of the mains plug.
2.Laser safety
This unit employs a laser. Only qualified service personnel
may remove the cover, or attempt to service this device
(due to possible eye injury).
Laser device unit
Type :SemiconductorlaserGaAlAs
Wavelength : 650nm (DVD)

Note: Use of controls or adjustments or performance of
procedure other than those specified herein, may result in
hazardous radiation exposure. Avoid direct exposure to
beam.

Warning
1.General
. All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD). Careless handing during
repair can reduce life drastically. Make sure that, during
repair, you are at the same potential as the mass of the
set by a wristband with resistance. Keep components and
tools at this same potential. Available ESD protection
equipment:
1) Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and earth cable)
4822 310 10671.
2) Wristband tester 4822 344 13999.
. Be careful during measurements in the live voltage
section. The primary side of the power supply , including
the heat sink, carries live mains voltage when you
connect the player to the mains (even when the player is
“off”!). It is possible to touch copper tracks and/or
components in this unshielded primary area, when you
service the player. Service personnel must take
precautions to prevent touching this area or components
in this area. A “lighting stroke” and a stripe-marked
printing on the printed wiring board, indicate the primary
side of the power supply.
. Never replace modules, or components, while the unit is
“on”.
2. Laser
. The use of optical instruments with this product, will
increase eye hazard.
. Only qualified service personnel may remove the cover
or attempt to service this device, due to possible eye
injury.
. Repair handing should take place as much as possible
with a disc loaded inside the player.
. Text below is placed inside the unit, on the laser cover
shield:

Lead-Free requirement for service
INDENTIFICATION:
Regardless of special logo (not always indicated)
One must treat all sets from 1.1.2005 onwards, according
next rules.
Important note: In fact also products a little older can also
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:
xUse only lead-free solder alloy Philips SAC305 with
order code 0622 149 00106. If lead-free solder-paste is
required, please contact the manufacturer of your
solder-equipment. In general use of solder-paste within
workshops should be avoided because paste is not easy
to store and to handle.
xUse only adequate solder tools applicable for lead-free
solder alloy. The solder tool must be able
oTo reach at least a solder-temperature of 400°C,
oTo stabilize the adjusted temperature at the
solder-tip
oTo exchange solder-tips for different applications.
xAdjust your solder tool so that a temperature around
360°C – 380°C is reached and stabilized at the 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.
xMix 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, clean carefully the
solder-joint from old solder alloy and re-solder with new
solder alloy (SAC305).
xUse only original spare-parts listed in the
Service-Manuals. Not listed standard-material
(commodities) has to be purchased at external
companies.
xSpecial information for BGA-ICs:
- always use the 12nc-recognizable soldering
temperature profile of the specific BGA (for
de-soldering always use highest 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
indicator-label in the bag, the BGA-IC possibly
still has to be baked dry. This will be
communicated via AYS-website.
Do not re-use BGAs at all.
xFor sets produced before 1.1.2005, containing
leaded soldering-tin and components, all needed
spare-parts will be available till the end of the
service-period. For repair of such sets nothing
changes.
xOn our website:
www.atyourservice.ce.Philips.com
You find more information to:
BGA-de-/soldering (+ baking instructions)
Heating-profiles of BGAs and other ICs used in
Philips-sets
You will find this and more technical information
within the “magazine”, chapter “workshop news”.
For additional questions please contact your local
repair-helpdesk.
