WARNING

GB

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.

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.

WAARSCHUWING

NL

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.

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.

“Pour votre sécurité, ces documents
doivent être utilisés par des spécia­listes agréés, seuls habilités à réparer
votre appareil en panne”.

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."

Varoitus !

Avatussa laitteessa ja suojalukituksen ohitettaessa olet alttiina
näkymättömälle laserisäteilylle. Älä katso säteeseen!

DK Advarse !

Usynlig laserstråling ved åbning når sikkerhedsafbrydere er

1) Open the DVD Tray by using the Open/Close Button
while the Set is ON and disconnect the mains supply after
removing the Tray Cover.

Note: If this is not possible, the DVD T ray has to be open

manually.

Take a mini screw driver about 2mm diameter and make
a marking 24mm from the tip as shown in figure 2. Place

marking and slide it towards the right as shown in figure

1 until the Tray moves out of the Front Panel.

2) Return the set to its upright position and remove the Tray
Cover as shown in Figure 3 and close the tray manually
by pushing it back in.

3) Loosen 11 screws and remove the T op Cover by lifting the
rear portion upwards before sliding it out towards the rear.

-7 screws on the back

-2 screws each on the left & right side

4) Loosen 7 screws & lift up the top edge of Front Panel
assembly to free some catches (see figure 3) before
sliding it out towards the front.

-5 screws on the bottom

-1 screw each on the left & right side

Dismantling of the MPEG Board

1) Loosen 4 screws A to remove the metal cover together
with MPEG board and remove the connector as shown in

Use Service Testprogram. By selecting the TUNER TEST test frequencies will be stored as preset frequencies automatically.

1)

If sensitivity of frequency counter is too low adjust to max. channel separation

(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!

2)

RC network serves for damping the IF-filter while
adjusting the other one.
