© WARNING
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 wrist wrap 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.
Safety components are marked by the symbol

After servicing and before returning the set to customer
perform a leakage current measurement test from all 

HANDLING CHIP COMPONENTS

SERVICE TEST PROGRAM
1. PRELIMINARY SETUP
•To enter the service test program hold the keys “PLAY”
and “STOP” depressed while turning POWER ON.
•The display shows the software-version of the built-in
microprocessor (e.g. “
85S”).
•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 test
programs below).
2. DISPLAY TEST
Purpose:Check the internal display driver of the µP and the
display segments.
•To enter the display test start service test program and
press the “NEXT” button.
•The display shows test pattern 1, all display segmants are
switched on.
•To exit the display test and return to the main menu press
the “STOP” button.
3. KEY & REMOTE CONTROL TEST
Purpose:Check operation of keys, cord remote control and
IR-remote control.
•To enter the key & remote control test start service test
program and press the “MODE” button.
•The display shows “--”.
•Hold keys on the set resp. the remote control depressed
and check corresponding key codes on the display of the
CD-player resp. the test patterns on the display of the
remote control. Codes and patterns can be found in table 1
(see flow chart on next page).
•To exit the key & remote control test and return to the main
menu press the “STOP” button.
4. PLAYBACK TEST WITH ERROR ANALYSIS
Purpose:Analyse errors that occur during playback.
•To enter the playback test start service test program and
press the “PROG” button. Note that the playback test can
only be entered if the CD-door is closed.
•The set reads the TOC and switches to stand-by mode.
•Press the “PLAY” button to start the error analysis.
As long as the playback is free of errors the display shows
track and time information as in normal play-mode. In case
of an error a corresponding error code will be displayed. The
meaning of this error code can be found in table 2 (see flow
chart on next page).
Note: Errors can either be
“fatal” or “non fatal” . Fatal errors
lead to a stop of the playback while non-fatal errors
only cause a short interruption of music. Fatal errors
are displayed as long as the set is connected to the
power source, non fatal errors are displayed untill 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- and inner-switch, movement of slide
servo and acceleration of discmotor.
•To enter the servo test start service test program and
press the “PLAY” button.
•The display shows “S
xy ”. “ x ” indicates state of door-
switch; “
y ” indicates state of inner-switch. x,y = “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.
•The focus servo loop is switched on and the set starts
searching the focus. If the focus is OK the display shows
“-F”, else “-F”.
•When the disc is turned manually “focus noise” is audible.
•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”.
Note: During this test the µP displays the speed-flag of the
CD7. As this IC can only monitor a small range of
speed deviation the displayed information is not very
reliable. In case of doubt check disc motor control
circuit.
•To enter the radial test press 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
output.
•The display shows “rd”.
•The radial servo loop is switched on, mute is released and
an audio signal is audible.
•To jump 10 tracks outside press the “NEXT” button.
•To jump 10 tracks inside press the “PREV” button.
•To exit the radial test and return to the main menu press
the “STOP” button.
