1. General saf
Safety regulations require that during a repair:
. Connect the unit to the mains via an isolation transformer.
. Replace safety components indicated by the symbol
y by components identical to the original ones. Any
onl
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

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

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:
x Use only lead-free solder alloy Philips SAC305 with

o To reach at least a solder-temperature of 400°C,
o To stabilize the adjusted temperature at the
solder-tip
o To exchange solder-tips for different applications.

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.
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).
x Use only original spare-parts listed in the
Service-Manuals. Not listed standard-material
(commodities) has to be purchased at external
companies.
x Special information for BGA-ICs:
- al
ways 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.
x For 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.
x On 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”.
