WAARSCHUWING
Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor electrostatische ontladingen (ESD).
Onzorgvuldig behandelen tijdens reparatie kan
de levensduur drastisch doen verminderen.
Zorg ervoor dat u tijdens reparatie via een
polsband met weerstand verbonden bent met
hetzelfde potentiaal als de massa van het
apparaat.
Houd componenten en hulpmiddelen ook op
ditzelfde potentiaal.
All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are
connected with the same potential as the mass
of the set via a wrist wrap with resistance.
Keep components and tools also at this
potential.
D
ATTENTION
Tous les IC et beaucoup d’autres
semi-conducteurs sont sensibles aux
décharges statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution n’est
prise à leur manipulation.
Lors de réparations, s’assurer de bien être relié
au même potentiel que la masse de l’appareil et
enfiler le bracelet serti d’une résistance de
sécurité.
Veiller à ce que les composants ainsi que les
outils que l’on utilise soient également à ce
potentiel.
WARNUNG
Alle ICs und viele andere Halbleiter sind
empfindlich gegenüber elektrostatischen
Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kan
die Lebensdauer drastisch reduzieren.
Veranlassen Sie, dass Sie im Reparaturfall über
ein Pulsarmband mit Widerstand verbunden
sind mit dem gleichen Potential wie die Masse
des Gerätes.
Bauteile und Hilfsmittel auch auf dieses gleiche
Potential halten.

AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevità potrebbe essere fortemente
ridatta in caso di non osservazione della più
grande cauzione alla loro manipolazione.
Durante le riparazioni occorre quindi essere
collegato allo stesso potenziale che quello della
massa dell’apparecchio tramite un braccialetto
a resistenza.
Assicurarsi che i componenti e anche gli utensili
con quali si lavora siano anche a questo
potenziale.

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 1 Jan 2005 onwards, according next rules:
Example S/N:
Bottom line of typeplate gives a 14-digit S/N. Digit 5&6 is the year, digit 7&8 is the week number,
so in this case 2005 wk12
So from 0501 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 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 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.
•
Use only adequate solder tools applicable for lead-free solder alloy. The solder tool must be able
o
To reach at least a solder-temperature of 40
o
To stabilize the adjusted temperature at the solder-tip
o
To exchange solder-tips for different applications.
−
is reached and stabilized at the solder joint. Heating-time of the
Adjust your solder tool so that a temperature around
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.
Special information for BGA-ICs:
- always use the 12nc-recognizable soldering temperature profile of the specific BGA (for de-soldering 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 indicator-label 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.

You will find this and more technical information within the "magazine", chapter "workshop news".
For additional questions please contact your local repair-helpdesk.
SERVICE INSTRUCTION
Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to
the following points:
·
·
·
·
Route the wire trees correctly and fix them with the
mounted cable clamps.
Check the insulation of the AC Power lead for external
damage.
Check the strain relief of the AC Power cord for proper
function.
Check the electrical DC resistance between the AC Power
Plug and the secondary side (only for sets which have a AC
Power isolated power supply):
1. Unplug the AC Power cord and connect a wire
between the two pins of the AC Power plug.
2. Set the AC Power switch to the "on" position (keep the
AC Power cord unplugged!).
3. Measure the resistance value between the pins of the
AC Power plug and the metal shielding of the tuner or
the aerial connection on the set. The reading should be
larger than 4.5 Mohm (For U.S. it should be between
4.2 Mohm and 12 Mohm).
4. Switch "off" the set, and remove the wire between the
two pins of the AC Power plug.
•
Check the cabinet for defects, to avoid touching of any
inner parts by the customer.
MW
– Use only the supplied speakers.
The combination of the main unit and
speakers provide the best sound.
Using other speakers can damage the
unit and sound quality will be negatively
affected.
– Never make or change connections
with the power switched on.
– Connect the AC power cord to the
power outlet only after you have finished
hooking up everything.
WARNING!
Connections
Connecting FM / MW
antennas
– Place the MW loop antenna on a shelf or
attach it to a stand or wall.
– Extend the FM antenna and fix its ends to the
wall.
– Adjust the position of the antennas for
optimal reception.
– Position the antennas as far as possible from a
TV, VCR or other radiation source to prevent
unwanted noise.
– For better FM stereo reception, connect
external FM antenna.
Step 1:
Connecting the
speakers
Connecting the AC
power cord
"AUTO INSTALL – PRESS PLAY" may appear
on the display panel when the AC power cord is
plugged into the power outlet for the first time.
Press ÉÅ on the main unit to store all available
radio stations or press Ç to exit (refer to
“Tuner Operations”).
Step 3:
Helpful Hint:
– Ensure that the speaker cables are correctly
connected. Improper connections may damage the

– Do not connect more than one speaker to any
one pair of +/- speaker terminals.
Connect the speaker wires to the SPEAKERS
terminals, right speaker to "R" and left speaker to
"L", coloured (marked) wire to "+" and black
(unmarked) wire to "-". Fully insert the
stripped por tion of the speaker wire into the
terminal as shown.

1) If sensitivity of frequency counter is too low adjust to max. channel separation
2) RC network serves for damping the IF-filter while adjusting the other one.
(input signal: stereo left 90% + 9%, adjust output on right channel to minimum)
3) For AM RF adjustments the original frame antenna has to be used !
These assembly drawings show a summary of all possible versions.
For components used in a specific version see schematic diagram respectively partslist.
Repeat
4) MW has to be aligned before LW.

CD DRIVE – LENS CLEANING
Before touching the lens it is advised to clean
the surface of the lens by blowing clean air over
it in order to avoid that little particles make
scratches on the lens.
Because the material of the lens is synthetic and coated
with a special anti-reflectivity layer, cleaning must be
done with a non-aggressive cleaning fluid. It is advised to
use “Cleaning Solvent B4”, available with codenumber
4822 389 10026.

PLAYABILITY CHECK
The laser current can be measured as a voltage drop on
resistor 3822. Typical value 55mV (DA11 disc drive).
80
If the value is higher than 80mV (DA11 disc drive) or the
current increases just after switching the laser on - the
laserdiode is most probably defective. In that case the CD
drive has to be replaced.
4. GENERAL HINTS
The actuator is a very precise mechanical component
and may not be damaged in order to guarantee its full
function. It is advised to clean the lens gently (don’t press
too hard) with a soft and clean cotton bud moistened with
the special lens cleaner.
Since the HF pre-amplifier is integrated into the new ”CD18“
signal processor the well-known eye pattern signal is not
available as external signal and cannot be measured anymore. Also measuring the offset voltages is not necessary
because the new signal processor contains an automatic
offset compensation.
The direction of cleaning must be in the way as indicated
in the picture below.
However the circuitry offers some new aspects for checking
the system:
- the Monitor voltage shows if the sensitivity is set correctly
(attention: ESD sensitive line!):
CD DA: 150mV
CD RW: 180mV
This document describes the version with the Sanyo CD drive DA11VF.
The CD drive used in a specific application is stated on the type plate, located on one
of the side walls of the changer module.
- the Focus search algorithm is divided into 4 steps:
1st step: CD DA sensitivity
2nd step: CD DA enforced sensitivity
3rd step: CD RW sensitivity
4th step: CD RW enforced sensitivity
TABLE OF CONTENTS
The used sensitivity can be found out by either measuring
the Monitor voltage or counting the up/down movements of
the OPU until focus is found.
e.g. when a normal CD DA is played back Monitor voltage
should measure 150mV respectively Focus should be found
within the first up/down movement of the OPU.

In case a higher sensitivity setting can be observed than
defined, there are following possible reasons:
- disc scratched or dirty
- poor reflectivity of the disc - disc not conform standard
- lens of the OPU dirty
- laser power too low

CAUTION
Dismantling of Drawer
CHARGED CAPACITORS ON THE SERVO BOARD MAY DAMAGE THE CD DRIVE ELECTRONICS WHEN
CONNECTING A NEW CD MECHANISM. THAT´S WHY, BESIDES THE SAFETY MEASURES LIKE
• SWITCH OFF POWER SUPPLY
• ESD PROTECTION
ADDITIONAL ACTIONS MUST BE TAKEN BY THE REPAIR TECHNICIAN.
The following steps have to be done when replacing the CD mechanism:
1. Disconnect flexfoil cable from the old CD drive
2. Put a paperclip onto the flexfoil cable to short-circuit the contacts (fig.1)
3. Remove the old CD drive
4. Remove paperclip from the flexfoil cable and connect it to the new CD drive
5. Position the new CD drive on its studs
6. Remove solder joint from the Laser unit (see below)
10-2
1. Open the drawer and release 2 catches
as shown in fig. 2
2. Pull drawer out.
fig.1
Attention: The laser diode of this CD drive is protected against ESD by a solder joint which short-circuits the
laser diode to ground.
For proper functionality of the CD drive this solder joint must be removed after connecting the drive to
the set.
fig.2
Assembling of Drawer
Emergency open
In case of a Supply fault, the drawer can be opened manually.
1. Remove the top cover of the set to get access to the CD Module.
2. Proceed as shown in picture below.
1. Check if slider is on the right side → see
picture below.
2. If necessary - move slider to the right end
position first.
3. Insert the Drawer.
