Safety Information

ESD

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.

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.

LX7500R

EN 5

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.

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.

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.

extension cable and earth cable)

SAFETY

Safety regulations require that the set has to be restored to its
original condition and parts which are identical with
those specified be used. Replace safety components
only by components identical to the original ones.
Safety components are marked by the symbol

Veiligheidsbepalingen vereisen, dat het apparaat in zijn
oorspronkeliijke toestand wordt teruggebracht en dat
onderdelen, identiek aan de gespecificeerde, worden toegepast.
De Veiligheidsonderdelen zijn aangeduid met het symbool

Les normes de sécurité exigent que l`appareil soit remis
à l`état d`origine et que soient utilisées les pièces de
rechange identiques à celles spécifiées.
Les composants de sécurité sont marqués

Le norme di sicurezza estigono che l´apparecchio venga
rimesso nelle condizioni originali e che siano utilizzati i
pezzi di ricambiago identici a quelli specificati.
Componenty di sicurezza sono marcati con

DANGER: Invisible laser radiation when open.
AVOID DIRECT EXPOSURE TO BEAM.

d
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten. Der Originalzustand des Gerätes
darf nicht verändert werden. Für Reparaturen sind Bauteile
gleicher Spezifikation zu verwenden. Für Sicherheitsbauteile
sind Originalersatzteile zu verwenden.

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.

Dismantling the Top Cover

Manual Opening the Tray

• Remove 9 screws as shown in picture 1.
• Release side walls on bottom and raise top cover
upwards.

In case the loader is defect or cannot be opened electrically, proceed
as follows:
• The tray can be released by means of screwdriver.
The locking slider of the tray can be accessed through a slot on
the bottom side of the set. To prevent dust coming into the drive
this slot is covered by an adhesive tape on the cabinet of the drive
(see picture 4).
Push through this adhesive tape and move the white pin of the
slider to the left side (see picture 5). The tray will move out a bit
and is now released.
• Pull the tray out.
Make sure that a new adhesive tape has been applied to the
drive when the repair is finished!

LEAD FREE PRODUCED SET
This set is manufactured with lead-free
production technology. This is also indicated by
the PHILIPS-lead-free logo you find on the
printed boards.
The set is produced with lead-free solder-alloy as well as
with lead-free sub-parts. It can be considered as lead-free.
Due to this fact some rules have to be respected by the
workshop during a repair:
• Use only lead-free soldering-tin Philips SAC305 with order
code 0622 149 00106. If lead-free solder-paste is required,
please contact the manufacturer of your solder-equipment.
• Use only adequate solder tools applicable for lead-free
soldering-tin.
• Adjust your solder tool so that a temperature around 217°
– 220° is reached at the solder joint.
• Do not mix lead-free soldering-tin with leaded soldering-tin.
This would lead to unreliable solder joints.
• On our website http://www.atyourservice.ce.philips.com
you find more information to
– aspects of lead-free technology
– BGA-de-/soldering, heating-profiles of BGAs used in
Philips-sets, and others.

NTC Amp(lifier): sensor for the temperature of the heatsink on
the Power Amplifier board.
The signals NTC_Front and NTC_Amp are compared with a

which controls the speed of the set fan.
In each test step of the temperature test the speed of the set
fan can be set in four steps.

5. Diagnostic Software
Due to the complexity of the DVD recorder, the time to find a
defect in the recorder can become long. To reduce this time,
the recorder has been equipped with Diagnostic and Service
software (DS). The DS offers functionality to diagnose the
DVDR hardware and tests the following:
• Interconnections between components
• Accessibility of components
• Functionality of the audio and video paths
This functionality can be accessed via several interfaces:
1. End user/Dealer script interface
2. Command Interface

5.1

End User/Dealer Script Interface

Description

5.1.2

Unplug the mains cord
Hold Open/Close & Source
depressed while plugging in
the mains cord

During the test, the display shows
the number of the test currently
running

SET O.K.?

YES

The End user/Dealer script interface gives a diagnosis on a
stand alone DVD recorder. During this mode, a number of
hardware tests (nuclei) are automatically executed to check if
the recorder is faulty. The diagnosis is simply a "fail" or "pass"
message. If the message "FAIL" appears on the display, there
is apparently a failure in the recorder. If the message "PASS"
appears, the nuclei in this mode have been executed
successfully. There can be still a failure in the recorder
because the nuclei in this mode don't cover the complete
functionality of the recorder.

To exit DEALER SCRIPT, unplug the mains cord

The End use/Dealer script executes all diagnostic nuclei that
do not need any user interaction and are meaningful on a
standalone DVD recorder.

5.3.2

Each nucleus returns an error code. This code contains six
numerals, which means:

If you want that the recorder starts up in Virgin mode, follow this
procedure:
• Unplug the recorder
• plug the recorder again while you keep the STAND BY/ON
key pressed
• the set starts up in Virgin mode.

Set-Up Physical Interface Components
Hardware required:
• Service PC
• one free COM port on the Service PC
• special cable to connect DVD recorder to Service PC
The service PC must have a terminal emulation program (e.g.
Hyperterminal) installed and must have a free COM port (e.g.
COM1). Activate the terminal emulation program and check
that the port settings for the free COM port are: 19200 bps, 8
data bits, no parity, 1 stop bit and no flow control. The free COM
port must be connected via a special cable to the RS232 port
of the DVD recorder. This special cable will also connect the
test pin, which is available on the connector, to ground (i.e.
activate test pin).
Code number of PC interface cable: 3122 785 90017
Activation Digital Board Chrysalis
1. Pull the mains cord from the recorder and reconnect it
again (reboot).
2. The next welcome message will appear on the PC:

Now, the prompt 'DS:>' will appear. The diagnostic software is
now ready to receive commands. The commands that can be
given are the numbers of the nuclei. If you see above shown
screen, continue with paragraph 'Nuclei Codes'.

In these cases, the boot EEPROM of the Chrysalis Digital
Board does not contain the required string with the hardware
information. To update the Digital Board with the correct string,
nucleus 1226 must be executed. See next section ’Diversity
