WARNING
ESD
NL
WAARSCHUWING
All ICs and many other semi-conductors 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 wrist wrap with resistance. Keep components and tools also at this potential.
Alle IC's en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen verminderen. 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.
F
ATTENTION
I
AVVERTIMENTO
Tous les IC et beaucoup d'autres semi-conducteurs sont sensibles aux décharges statiques (ESD). Leur longévité pourrait être considérablement écourtée par le fait qu'aucune précaution n'est prise à leur manipulation. Lors de réparations, s'assurer de bien être relié au même potentiel que la masse de l'appareil et enfiler 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
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 riparazioni occorre quindi essere collegato allo stesso potenziale che quello della massa dell'apparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.
Alle ICs und viele andere Halbleiter sind empfindlich gegenüber elektrostatischen Entladungen (ESD). Unsorgfältige Behandlung im Reparaturfall kan die Lebensdauer drastisch reduzieren. Veranlassen Sie, dass Sie im Reparaturfall über ein Pulsarmband mit Widerstand verbunden sind mit dem gleichen Potential wie die Masse des Gerätes. Bauteile und Hilfsmittel auch auf dieses gleiche Potential halten.

Gameport Operations
WARNING Under no circumstances should you try to repair the system yourself, as this will invalidate the warranty. Do not open the system as there is a risk of electric shock. If a fault occurs, first check the points listed below before taking the system for repair. If you are unable to remedy a problem by following these hints, consult your dealer or Philips for help. Problem Solution
If the signal is too weak, adjust the antenna or connect an external antenna for better reception. Increase the distance between the system and your TV or VCR. Radio reception is poor.

Connect your game console's video and audio output to the GAMEPORT video and audio inputs respectively (refer to "Connections Connecting to game console).
The timer is not working.
To adjust the game console's volume level Adjust GAME VOLUME.
The remote control does not function properly.
2
Connect your TV's video input to the VIDEO OUT (CVBS) on the rear panel.
Select the source (CD or TUNER, for example) before pressing the function button (É S , T). Å, Reduce the distance between the remote control and the system. Replace the battery. Point the remote control directly toward the IR sensor. Set the clock correctly. Press TIMER ON/OFF to switch on the timer. Press and hold DEMO STOP on the main unit to switch off the demonstration mode.
3
Connect all the AC power cord to the power outlet.
Notes: You can only activate GAME VOLUME and MIXIT while in the game source mode. If your game console is switched on, the video image will always appear on the TV even though you are not in the gameport mode.
Starting operation
The system displays features automatically and buttons start flashing.

Turn on the TV and set to the correct video-in channel. The TV's video input channel may be called AUX(iliary) IN, AUDIO/VIDEO (A/V) IN, EXT 1, etc. These channels are often near channel 00 on your TV. Or, your TV remote control may have a button or switch that chooses different video modes. See your TV manual for details.
Refer to the FAQ (Frequently Asked Questions) on the supplied CD-ROM or visit our website "www.audio.philips.com" for latest update on FAQ.

Step 3: Connecting to the game console
IMPORTANT! Gameport inputs are for the game console only.
Connections
a. Use the game console's video cable (not
supplied) to connect its video output to the GAMEPORT-VIDEO terminal.
MW
b. Use the game console's audio cables (not
supplied) to connect its audio outputs to the GAMEPORT-AUDIO L. / AUDIO R. terminals.
Speaker Speaker
c. Use the video cable (yellow) to connect the
VIDEO OUT terminal to the video input on the TV for viewing.
Warning! Use only the supplied speakers. The combination of the main unit and speakers provides the best sound. Using other speakers can damage the unit and sound quality will be negatively affected. Never make or change connections with the power switched on. Connect the AC power cord to the power outlet only after you have finished hooking up everything. To avoid overheating of the system, a safety circuit has been built in.Therefore, your system may switch to Standby mode automatically under extreme conditions. If this happens, let the system cool down before reusing it (not available for all versions).
Step 1: Connecting FM/MW antennas
1-9
Rear pane l
Notes: On the TV, the Video Input jack is usually yellow and might be labeled A/V In, CVBS, Composite or Baseband. To avoid magnetic interference, do not position the front speakers too close to your TV.
Place the MW loop antenna on a shelf or attach it to a stand or wall. Extend the FM antenna and fix its ends to the wall. Adjust the position of the antennas for optimal reception. Position the antennas as far as possible from a TV, VCR or other radiation source to prevent unwanted noise. For better FM stereo reception, connect the external FM antenna.
Step 4: Connecting the AC power cord
Step 2: Connecting the speakers
OUT
"AUTO INSTALL - PRESS PLAY" may appear on the display panel when the AC power cord is plugged into the power outlet for the first time. Press É on the main unit to store all available Å radio stations (page 3 - P3) or press Ç to exit (refer to "Tuner Operations").

Repair Hint
Figure 16
1) During repair it is possible to disconnect the Tuner Board and CDC Module completely unless the fault is suspected to be in that area. This will not affect the performance of the rest of the set. 2) Due to the short flex cable wires in the ETF Module, the PCB should be disconnected and reconnected on the reverse side of the tape mechanism to keep it electrically connected during repair. see Figure 19. Note: The flex cables are very fragile, care should be taken not to damage them during repair. After repair, be very sure that the flex cables are inserted properly into the flex sockets before encasing, otherwise faults may occurs.
1) Loosen 6 screws H (see Figure 16) to remove the ETF Tape Module.

EEPROM TEST
Activated with
R
ACTION
A test pattern will be sent to the EEPROM. "PASS" is displayed if the uProcessor read back the test pattern correctly, otherwise "ERROR" will be displayed. Load default data. Display shows "NEW" for 1 second. Caution! All presets from the customer will be lost!! Display shows value for 2 seconds. Values increases or decreases in steps of 1 until 0 (Min.) or 40 (Max.) is reached.

ROTARY ENCODER TEST
Rotary Volume Knob
Note: * Depending on the selected grid frequency (9 or 10kHz) By holding the TUNER and R buttons depressed while switching on the Mains supply, one of the undermentioned features will be activated: - the tuning grid frequency is toggled between 9kHz and 10kHz for the Oversea (/21) version. - the extended FM1 (65.81MHz - 74MHz) is toggled on and off for East Eur. (/34) version.

Use Service Testprogram. By selecting the TUNER TEST test frequencies will be stored as preset frequencies automatically.
1) If sensitivity of frequency counter is too low adjust to max. channel separation 2) RC network serves for damping the IF-filter while adjusting the other one. 4) MW has to be aligned before LW.
(input signal: stereo left 90% + 9%, adjust output on right channel to minimum)
3) For AM RF adjustments the original frame antenna has to be used !
