Philips CDR-800, CDR-802, CDR-820, CDR-822 Service manual

For servicing CDR8xx 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.

The Switched Mode Power Supply unit will be exchanged completely in case of a failure.

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 this 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.

After servicing and before returning the set to customer
perform a leakage current measurement test from all
exposed metal parts to earth ground, to assure no
shock hazard exists.
The leakage current must not exceed 0.5mA.

AVOID DIRECT EXPOSURE TO BEAM.

Dismantling the

Tray Covers

To dismantle the ornamental cover, the tray has to be moved out first.
This can either be done by activating the Open/Close-key or manually.
In order to avoid unnecessary loading it is recommended to move the tray out manually a few centimetres.
To release the tray manually proceed as shown in pictures 3, 4 and 5. The tray will move out a little.
Afterwards it can be pulled out as far as convenient.
