HANDLING CHIP COMPONENTS

GB
WARNING
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.
F
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.
ESD
D
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.
NL
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.
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 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.
“Pour votre sécurité, ces documents
doivent être utilisés par des spécia-
listes agréés, seuls habilités à réparer
votre appareil en panne”.
GB
Safety regulations require that the set be restored to its original
condition and that parts which are identical with those specified,
be used.
NL
Veiligheidsbepalingen vereisen, dat het apparaat bij reparatie in
zijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen,
identiek aan de gespecificeerde, worden toegepast.
F
Les normes de sécurité exigent que l’appareil soit remis à l’état
d’origine et que soient utiliséés les piéces de rechange identiques
à celles spécifiées.
D
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu
beachten. Der Original zustand des Geräts darf nicht verändert werden;
für Reparaturen sind Original-Ersatzteile zu verwenden.
I
Le norme di sicurezza esigono che l’apparecchio venga rimesso
nelle condizioni originali e che siano utilizzati i pezzi di ricambio
identici a quelli specificati.
"After servicing and before returning set to customer perform a
leakage current measurement test from all exposed metal parts to
earth ground to assure no shock hazard exist. The leakage current
must not exceed 0.5mA."

Repair Hints
3) During repair it is possible to disconnect the Tuner board
and CDC Module completely unless the fault is sus-
pected to be in that area. This will not affect the
performance of the rest of the set.
4) Due to the short flex cable wires in the ETF Module, the
pc board should be disconnected and reconnected on
the reverse side of the tape mechanism to keep it
electrically connected during repair. See picture 3.
Note: The flex cables are very fragile, care should be taken
not to damage them during repair. After repair, be
very sure that the flex cables are inserted properly
into the flex sockets before encasing, otherwise faults
may occurs.

Error Description
Focus Error
Triggered when the focus could not be found within a certain time when starting up the CD
or when the focus is lost for a certain time during play.
Radial Error
Triggered when the radial servo is off-track for a certain time during play.
Sledge In Error
The sledge did not reach its inner position (inner-switch is still close) before approximately
6 Sec. have passed by. Inner-switch or sledge motor problem.
Sledge Out Error
The sledge did not come out of its inner position (inner-switch is still open) before approximately
250 mSec. have passed by. Inner-switch or sledge motor problem.
Jump-offtrack error
Triggered in normal play when the jump destination could not be found within a certain time.
When this error occurred, software will try to recover by initiating the jump command again.
If it is recoverable, the disc will continue to play.
Subcode Error
Triggered when a new subcode was missing for a certain time during play.
PLL Error
The Phase Lock Loop could not lock within a certain time.
Turntable Motor Error
Generated when the CD could not reached 75% of speed during startup within a certain time.
Discmotor problem.
Focus Search Error
The focus point has not been found within a certain time.
The carousel switch is not open within certain time. This can happen when either the switch is
defective and closed all the time, or when the carousel is blocked when located exactly at a
disc position.
The carousel position switch did not close within a certain time. This can happen when the
switch is defective and never closes electrically, or when the carousel is blocked in between
two disc positions. The time-out is approximately 5 Sec.
The drawer could not enter the inside position is opening again. This can be caused because
the drawer is blocked by something and cannot go fully inside, or the drawer switch is defective
and does not close.
