All ICs and many other semiconductors 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 wristband with
resistance. Keep components and tools at this potential.
f ATTENTION
Tous les IC et beaucoup d´autres semi-conducteurs sont
sensibles aux décharges statiques (ESD). Leur longévite
pourrait être considérablement écourtée par le fait qu´aucune
précaution nést prise à leur manipulation.
Lors de réparations, s´assurer de bien être relié au même
potentiel que la masse de l´appareil et enfileer 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.

d WARNUNG
Alle ICs und viele andere Halbleiter sind empfindlich
gegenüber elektrostatischen Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kann die
Lebensdauer drastisch reduzieren.
Sorgen Sie dafür, daß Sie im Reparaturfall über ein Puls-
armband mit Widerstand mit dem Massepotential des
Gerätes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.
ñ WAARSCHUWING
Alle IC´s en vele andere halfgeleiders zijn gevoelig voor
electrostatische ontladingen (ESD).
Onzorgvuldig behandelen tijdens reparatie kan de levensduur
drastisch doen vermindern. 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.
i 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 riparationi occorre quindi essere
collegato allo stesso potenziale che quello della massa
delápparecchio tramite un braccialetto a resistenza.
Assicurarsi che i componenti e anche gli utensili con quali si
lavora siano anche a questo potenziale.
Safety regulations require that the set be restored to its
original condition and that parts which are identical with
those specified be used.

1. Dismantle bottom and printed board/drive assembly
2. Disconnect membrane keyboard
(flex-foil connector on copperside of printed board)
3. Bend the cabinet leftwards downwards 1,
while bending the CD-door rightwards upwards 2
The procedure appears to be tricky at first, but force
needs to be applied with thumb and middle finger only.
It’s just like snapping one’s fingers.
Remark: Don’t worry about applied force - both parts have a
solid design. However, do not use screwdrivers or
tools like that. Sharp edges could damage hinge or

SERVICE TEST PROGRAM
1. PRELIMINARY SETUP
• To enter the service test program disconnect the AC/DC adaptor
and remove batteries, open the CD-door and hold the buttons
“PLAY” & “PREV” depressed while turning power on (i.e.
connecting the AC/DC adaptor).
• The display shows the software version of the built-in µP
(i.e. “S-26”). Versions are counted from “ 00” onwards; that
means the higher the number the newer the software.
• The program is now in the main menu – various tests can be
entered by pressing the corresponding buttons (see flow chart on
next page or detailed description of available tests below).
• To exit the service test program press the “STOP“ button or
disconnect the set from the power source.
2. DISPLAY TEST
Purpose: Check functionality of display and display driver.
• To enter the display test start the service test program and press
the “NEXT” button.
• The display shows test pattern1. All segments are activated for
finding open circuits (see flow chart on next page).
• To jump to the next pattern press the “NEXT” button.
• The display shows test pattern2. All alternate pins (2, 4, ...) are
activated for finding short circuits (see flow chart on next page).
• To jump back to test pattern1 press the “NEXT” button, to exit the
display test and return to the main menu press the “STOP” button.
3. KEY TEST
Purpose: Check operation of keys and cord remote control.
• To enter the key test start the service test program and press the
“MODE” button.
• The display shows “--”.
• Hold key depressed and check corresponding key code on the
display. Key codes can be found in table1 (see flow chart on next
page).
• To exit the key test and return to the main menu press the “STOP”
button.
4. PLAYBACK TEST WITH ERROR ANALYSIS
Purpose: Analyze errors that occur during playback and search for
intermittent failures.
• To enter the playback test start the service test program and press
the “BASS” button.
• To start the error analysis press the “PLAY” button. Note that the
playback test can only be entered if the CD-door is closed.
• The set will read the TOC and start playback.
As long as the playback is free of errors the display shows track and
time information like in normal play-mode. In case of errors
corresponding error codes will be displayed. The meaning of these
error codes can be found in table2 (see flow chart on next page).
Note:
Errors can either be
“fatal”
or
“non fatal”
. Fatal errors always
stop the playback, non fatal errors only cause a short
interruption of the music. Fatal errors are displayed as long
as the set is connected to the power source, non fatal errors
are displayed until a new error occurs or a button is pressed.
• To stop the playback test disconnect the set from the power
source.
5. SERVO TEST
Purpose:
Check door switch, inner switch of CD-drive, movement
of slide and acceleration of discmotor.
• To enter the servo test start the service test program and press
the “PLAY” button.
xy
• The display shows “Cd
”.
“x” indicates state of door switch;
“y” indicates state of inner switch.
x,y
= “0” means switch is closed; “1” means switch is open.
• To move slide outside hold the “NEXT” button depressed.
• To move slide inside hold the “PREV” button depressed.
• To accelerate the discmotor clockwise hold the “MODE” button
depressed.
• To accelerate the discmotor counter-clockwise hold the “PROG”
button depressed.
• To enter the focus test press the “PLAY” button, to exit the servo
test and return to the main menu press the “STOP” button.
6. FOCUS TEST
Purpose: Check movement of lens and operation of focus servo for
CDDA and CDRW discs.
Since the CDRW reflects much less light than an ordinary CDDA, the gain
of the HF-amplifier stage and the sensitivity of the ADC inside the
Decoder&Digital Servo IC “CD10” must be adapted accordingly.
The gain is switched via the CDRW input of the HF-preamplifier.
The ADC-sensitivity is set via software parameters (sent from µP to
“CD10”). In total, there are 4 sensitivity modes available: 1 for CDDA and
3 for CDRW. The modes are listed in table3 (see next page).
In normal play-mode, the correct focus sensitivity is choosen
automatically during start-up (see “Start-up procedure” on previous page).
In the service test program, the sensitivity can be choosen manually in
order to allow individual measurements in several modes.
• The focus servo loop is switched on and the set starts searching
the focus (“focus ramping”). As soon as the focus has been found
the focus servo loop is closed and the state of the focus is
monitored continuously.
x
• If the focus is OK the display shows “ F
”, else “-Fx”.
“x” indicates the sensitivity mode. Details can be found in table3
(see flow chart on next page).
• To toggle between sensitivity modes press the “BASS” button.
• To move slide outside hold the “NEXT” button depressed.
• To move slide inside hold the “PREV” button depressed.
• To accelerate the discmotor clockwise hold the “MODE” button
depressed.
• To accelerate the discmotor counter-clockwise hold the “PROG”
button depressed.
• In case the focus is OK the discmotor test can be entered by
pressing the “PLAY” button, to exit the focus test and return to the
main menu press the “STOP” button.
7. DISCMOTOR TEST
Purpose: Check speed regulation of discmotor.
• The speed regulation is switched on and the discmotor starts
rotating. If the speed reaches 75% of the nom. speed the display
shows “ d”, else “-d”.
• In parallel also the state of the focus is monitored continuously
(display “ F
x
” or “-Fx”).
• In case the disc speed is OK and the focus is OK the radial test
can be entered by pressing the “PLAY” button, to exit the
discmotor test and return to the main menu press the “STOP”
button.
8. RADIAL TEST
Purpose: Check if radial loop locks and an audio signal is audible
at the headphone output.
• The radial servo loop is switched on, mute is released and the
audio signal is audible. If the system is on track the display shows
“ r”, else “-r”.
• In parallel also the disc speed (display “ d” or “-d
of the focus (display “ F
x
” or “-Fx”) are monitored continuously.
”) and
the
state
Note: In case of radial errors the audio output is muted and muting
is not released automatically when the systems recovers from the
error. “-r” remains on the display.
To open mute again press the “NEXT” or “PREV” button.
• To jump 16 tracks outside press the “NEXT” button.
• To jump 16 tracks inside press the “PREV” button.
• To exit the radial test and return to the main menu press the
“STOP” button, to exit the service test program disconnect the set
from the power source.
Important remark:
In radial test mode data to the DRAM is written at 1.2 times the
nominal speed, and read from the DRAM at nominal speed.
Because writing is done faster than reading the DRAM gets full after
a certain time.
In normal play mode the system would now wait until the DRAM is
partly emptied again, jump backwards and resume filling at the last
written position. However, in radial test mode the jumps would
disturb measurements on the radial servo loop.
Therefore this function has been disabled and filling restarts
immediately from the current position of the pick-up unit. As a result
“jumps” are audible during playback.
