Philips FWR-33 Service Manual

For servicing the FW-R33 and FW-R55 the set has to be divided into two parts:

1. Except for the CD-R/W module all workshops can repair the set on component level.

2. The CD-R/W module can only be repaired on component level with the help of ComPair.
With this tool diagnosing of the set can be done in an interactive way. In the tool also the adjustment procedure has been
implemented. The adjustment is absolutely necessary in case the CDR Main Board and/or CD drive (CDR Loader) is
disconnected from the matched production combination.

Only designated workshops can perform these repairs!

Please send the complete set to the designated workshop.

© 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 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 Puls­armband 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.

Handling chip components

The sets are equipped with a special DEALER MODE.
This mode blocks the trays of the CDC - and CDR module to prevent customers from fetching out CDs from exhibition sets.
The dealer mode can be switched on/off as follows:

1) Switch the set with the stanby-button to standby mode

2) Press the [DISPLAY] key for longer than 5s
→ Display shows „ TRAYS LOCKED“ respectively „ UNLOCKED“

Escape from „Dealer Mode“

The demo mode displays various features of the set and will start automatically.
To cancel the demo mode keep „STOP“ button on the set pressed for at least 5 seconds.
The demo mode is cancelled permanently. The set switches to standby.
