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

Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten. Der Originalzustand des Gerätes
darf nicht verändert werden. Für Reparaturen sind Originalersatzteile zu verwenden.
Sicherheitsbauteile sind durch das Symbol markiert.
© 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.

Veiligheidsbepalingen vereisen, dat het apparaat in zijn

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.

FIRMWARE UPGRADE
Occasionally, Philips will release new firmware for the
microcontroller and Audio-DSP on the Video Processing
Board. The binary firmware upgrade file(s) will be made
available via the official service channels (i.e. symptom/cure
system and/or customer care website).
To upgrade the firmware proceed as follows:
1. Download and install the communication application
“Telix for DOS” (http://www.telix.com/).
2. Download the binary upgrade file and copy it to the
“SEND” folder within the Telix-directory. Upgrade files
have the extension “.001”, e.g. “Vp50.001”.
3. Connect the VPB board (connector 1009) with the power
supply (power not switched on yet).
Connect the VPB board via connector 1012 (white
connector with 7 pins) with the Interface-Board (VPBInterface).
4. Start “TELIX.EXE” (if a window with the following error
message appears, just select “ignore”).
5. Press <Alt> + <p> to initialize the COM-port.
Select Speed 115200 (press I) and the used COM-port
(press number):
Press <Enter> to close the window.
6. Switch on the power supply and press the RESET-button
on the interface-board (RESET = pin1 on VPB connector
1011).
In the Telix-window “INT DOWNLOAD START” appears:
If this message doesn’t appear, then there’s something
wrong with the communication.
7. Press the following keys in sequence:
<f> <p> <c> <Enter>
In the Telix-window “PREPARED” appears:
8. Press the following keys in sequence:
<f> <c> <f> <Enter>
In the Telix-window “CLR START” appears:
9. Press <Alt> + <s>, select “1k-Xmodem” in the pop-upwindow (with cursor keys) and press <Enter>.
10. Press <Tab>, select directory “SEND\” (with cursor
down) and press <Enter>.
2-2
11. Now select the supplied firmware-file and press <Enter>.
12. Press <F10> and wait until the download has finished.
If the message “Telix Warning, upload was aborted”
appears during download, check connections and restart at
point 6.
13. To program another board, restart at point 6 or press
<Alt> + <x> to close Telix.
SERVICE TEST PROGRAM
The Digital A/V Receiver DFR9000 is equipped with
comprehensive service & diagnostic features. The set
internal service mode provides following test loops:
• EEPROM test
• EEPROM format
• Display test
• Key/RC/Rotary test
• I2C & SPI communication test
• DAB bit error rate test
• Audio switch test
• Video switch test
• Video test patterns
• Temperature & fan test
1. Entering the service mode
To enter the service mode hold the button <PREVIOUS>
depressed while connecting mains.
The set will enter the main menu of the service mode and
display the following message:
Left part of LCD Middle part of LCD
L xx yy mm dd.dd
L...........Country code (E=EU, U=US, O=OS)

7. DAB bit error rate test
Purpose: Reads and displays the bit error rate of the DAB
tuner.
Notes: “rrr.rr” is the bit error rate in %.
“NO VALUE” is shown if no station is available. In
this case connect antenna or the test signal and
press the DAB ErrorBitRate button again. The
module will scan band III and the L band for stations
(about 2 minutes) and tune to the first station found.
It is possible to set the DAB module to a defined
center frequency. Press “RIGHT” on the RC and
229.072 MHz center frequency (228.304 till 229.840
with block name 12D) will be selected. Use “RIGHT”
and “LEFT” to select another frequency. Press the
DAB ErrorBitRate button to tune to the frequency.
7. Audio switch test
Purpose: Switches several audio modes according to the
table below. System related limitations are
ignored.
Notes: All DAC/CODEC outputs are routed to amplifiers/line
out sockets. If connecting ADC data output to all data
inputs of CODEC/DAC in parallel, input signal to
ADC will show on all outputs.
The test starts with -30dB as volume setting.
VOLUME (at least rotary) will work setting the
volume level. BASS/TREBLE will be 0dB (not
changeable). The routing will be influenced by HP
connect (HP out instead of LS). Line out and record
out is always active (L+R).

8. Video switch test
Purpose: Switches several video modes according to the
table below. System related limitations are
ignored.
Note: Video signal is shown on the video outputs without
any enhancement.
9. Video test patterns
Purpose: Activates video test patterns of the following ICs in
sequential order: Denc → Faroudja → VIP → OSD
→ HDMI receiver → HDMI transmitter

10. Temperature & fan test
Purpose: This test measures the temperature inside the set
and switches the fan speed for both fans in
parallel.
Note: “FAN FAIL” indicates fan current out of range.
Standby-LED Blinking State
When the set is in standby mode and the Standby-LED is
blinking, the internal protection circuits have detected a
serious problem and the set won’t wake up anymore.
Errors are reported via the “ERR_FLAG” line, which can be
triggered from following circuitries:
• DC protection on UCD Amplifiers
(see UCD , components around transistor 7212)
→ Most likely, one of the UCD Amplifiers is defective and
must be replaced.
• Overvoltage protection for +5V and +12V on ASP Board
(see ASP Board , components around transistor 7604)
→ Most likely, Power Supply AC6750 is defective and
must be replaced.
