EN 52.LX9000RSafety Information
© 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.
©
Safety regulations require that the set be restored to its
original condition and that parts which are identical with
those specified be used.

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.

Remote Control
English
Inserting the batteries
1 Open the battery compar tment of the remote control and
insert 2 alkaline batteries, type AA (R06, UM-3).
2 Close the battery compar tment.
Do not use old and new or different types of batteries in
combination.
Remove batteries if they are empty or if the remote control
will not be used for a long time.
Batteries contain chemical substances, so they should
be disposed of properly.
Using the remote control
With this remote control you can control the
DVD recorder system as well as other Philips appliances
such as a Philips TV,VCR or CD player.
To control a Philips appliance, briefly press the
corresponding source key (TV, SAT, CAM 1/2, CD, CDR or
VCR) on the remote control. Some of the remote control
keys, e. g. 2, 0–9, CH+, CH–, 4, ¢, 9, 2; can be used
to control the appliance then.To control the DVD recorder
system with these keys, press TUNER or DVD/MON.
To select a source on the DVD recorder system, keep the
source key (TV, SAT, CAM 1/2, CD, CDR or VCR) on the
remote control pressed for 1 second.
To select CAM 2 (or TAPE, GAME), fir st select CAM 1 (or
CDR,VCR), then keep the corresponding key pressed for

Initial installation
When you connect the DVD recorder system to the mains
supply for the first time, you need to perform some basic
settings. Please observe the TV screen and the display of
the DVD recorder system.
1 Switch on your TV.

Dismantling the
Front panel assembly
The front panel assy consists of 2 cabinet parts, the ornamental
aluminium front and the plastic front cabinet where the printed circuit
boards and other technical parts are mounted.
Dependent on the location which is wanted to be accessed the front
panel assy can be detached either as complete assy or separated in
aluminium front and plastic front.
To avoid scratches on the ornamental part it is recommended
always to remove the aluminium front first.
Attention:
During dismantling and mounting the front panel assy the
connection pins of the display-motor may touch the metal
cabinet. This short circuit easy causes a destruction of safety
resistor 3550, located on Key Board left. Charged capacitors
deliver sufficient energy even when the set is switched off.
Therefore insolate the motor connections with a piece of
insolating tape before pulling out the front assy!
Dismantling the
ornamental Aluminium Front
• Loosen 8 screws as shown in picture 23 and 24.
• Remove the front flap by loosening the axles first → see picture 25
• Release 7 catches as shown in picture 26 and 27.
• Pull Aluminium Front slightly frontwards.

The Quartz test allows a quick check of the oscillator of the
Front µP without any influence to the oscillator circuitry by the
test equipment.
The factory can check if the correct quartz has been
assembled.
A 50% duty pulse of the divided oscillator frequency is put on
pin 18 of the µP (MDM_SCL).
To avoid dismantling of the front cabinet the test signal can best
be measured on pin 9 of 1802, located on the MDM board.
TEMPERATURE TEST
The temperature test is used to check the NTC resistors which
measure various temperatures to control the speed of the basic
engine fan and the set fan.
NTC Front: sensor for ambient temperature, located on
Key board left.
Controls the fan of the basic engine.
NTC Supply: sensor for the temperature of the heatsink on
the Power Secondary board.
NTC Amp(lifier): sensor for the temperature of the heatsink on
the Power Amplifier board.
NTC Trafo: sensor for the temperature of the main
transformer.
The signals NTC Supply, NTC Amp and NTC Trafo are
compared with a special algorithm and result in the control
signals SetFan1 and SetFan2 which control 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.

The test checks writing and reading of data to the EEPROM.
A test pattern is written to the first location in the EEPROM.
PASS is displayed when the test pattern is read back correctly,
else ERR.
Each software module using the EEPROM is forced to write the
default values in its part of the EEPROM.
This test should only be used to clear the EEPROM in case
of a µP-"hangup".
The DISPLAY test is intended to check the driver circuits,
the display module and the LEDs for open- or shortcircuits.
The LEDs
Standby, Instant Record
and
Record
can be
switched on/off separately.
The intensity of the backlight LEDs can be switched in 3
steps: full, half, off

The Audio tuner test is intended to read out the tuner version selected by the front µP.
The correct tuner version is defined by the version detection resistor 3444 mounted on
the Front - Control board. 3444 mounted = USA version without RDS.
The stored preset frequencies serve as provision for other tuner modules only.
