Map of DVD Regions
What are "regional codes"?
Motion picture studios want to control the home release of movies in different countries because theater releases arenít
simultaneous (a movie may come out on DVD in the US when itís just hitting screens in Europe). Therefore they have
required that the DVD standard include codes which can be used to lock out the playback of certain discs in certain geo-
graphical regions. Players sold in each region will have that regionís code built into the player. The player will refuse to play
these "region coded" discs which are not allowed in the region. However, regional codes are entirely optional. Discs without
codes will play on any player in any country. Some studios have already announced that only their new releases will have
regional codes. There are six regions:
1. United States and Canada
2. Europe and Japan
3. Far East (except Japan & China)
4. South America and Oceania
5. Africa and the Middle East
6. China (except Hong Kong)

REGION CODE
THE DISCS THAT THE DV4100 CAN HANDLE
The following discs can be played back with a DV4100.
Note: The regional code of the discs must meet to the regional
code of the DV4100.
DVD INFORMATION
Below is a glossary of the new terms related to DVD.
Title:
A disc may have more than one story/movie on it, so each
story/movie is called a “title”.
For example, if there are 2 movies on the disc, they are
separated into Title 1 and Title 2.
Chapter:
A title may also be separated into chapters.
For example, a movie (title) may be separated into 3 scenes
(chapters).
Subtitles:
DVDs are recorded with up to 32 different subtitle languages.
If a disc has more than one subtitle language, you can select
the subtitle language that you want to read.
Soundtrack language:
DVDs are recorded with up to 8 different soundtrack languages.
If a disc has more than one language, you can select the
soundtrack language that you want to listen to.

5. WARNING AND LASER SAFETY INSTRUCTIONS
SHOCK, FIRE HAZARD SERVICE TEST:
CAUTION: After servicing this appliance and prior to returning to customer, measure the resistance between
either primary AC cord connector pins (with unit NOT connected to AC mains and its Power switch ON), and the
face or Front Panel of product and controls and chassis bottom,
Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC
power is applied, and verified before return to user/customer.
Ref.UL Standard NO.1492.
NOTE ON SAFETY:
Symbol
: Fire or electrical shock hazard. Only original parts should be used to replace any part with symbol
Any other component substitution(other than original type), may increase risk or fire or electrical shock hazard.
F
ATTENTION
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 a 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 a ce que les composants ainsi que les
outils que l’on utilise soient également a ce
potentiel.
D
WARNUNG
Alle IC und viele andere Halbleiter sind
empfindlich gegen elektrostatische
Entladungen (ESD).
Unsorgfältige Behandlung bei der Reparatur
kann die Lebensdauer drastisch vermindern.
Sorgen sie dafür, das Sie im Reparaturfall
über ein Pulsarmband mit Widerstand mit
dem Massepotential des Gerätes verbunden
sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls
auf diesem Potential.
WAARSCHUWING
Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor elektrostatische 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.
AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevita potrebbe essere fortemente
ridatta in caso di non osservazione della piu
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.
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.
WARNING
Safety regulations require that the set be restored to its original condition
and that parts which are identical with those specified be used.
Veiligheidsbepalingen vereisen, dat het apparaat in zijn oorspronkelijke
toestand wordt terug gebracht en dat onderdelen, identiek aan de
gespecifieerde worden toegepast.
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten.
Der Originalzustand des Gerats darf nicht verandert werden.
Fur Reparaturen sind Original-Ersatzteile zu verwenden.
Le norme di sicurezza esigono che l’apparecchio venga rimesso nelle
condizioni originali e che siano utilizzati pezzi di ricambiago idetici a quelli
specificati.
Les normes de sécurité exigent que l’appareil soit remis a l’état d’origine et
que soient utilisées les pièces de rechange identiques à celles spécifiées.

Warning for powersupply on position 1005
The primary side of the powersupply including the heatsink carrieslive mains voltage when the
player is connected to the mains even when the player is swiched off !
This primary area is not shielded so it is possible to touch copper tracks and/or components when
servicing the player. Service personnel have to take precautions to pre vent touching this area or
components in this area .
The primary side of the powersupply has been indicated with a lightning stroke and a stripe-marked
printed on the printed wiring board
Note:
The screws on the basic Engine (position 218 in on the exploded view drawing) may never be
touched removed or re-adjusted.
Handle the Basic engine with care when the unit has to be exchanged!
The mechanism of the basic engine is very sensative for droping or shocks
!

6.1 DVD-Module 218
The DVD mechanism has to be exchanged completely in case
of failure. A new or repaired mechanism can be ordered with
codenumber 9305 023 61001.
Return the defective unit complete assembled in original
package to Philips Consumer Service in Eindhoven.
The monoboard has to be repaired on component level.

DISPLAY?
Check presence of high pulses at pin 23 of IC7104 while pressing a key on remote control.
Check IR receiver 6610.
Check safety resistor R3131.
Diagnostic software “Player script” : Remote control test.
Check if voltage at connector 1117-1 is 4.9V when power on (no light)
Check if voltage at base of Tr 7109 is 4.9V when power on (no light).
Check if voltage at connector 1117-1 is 3.33V during standby (light).
Diagnostic software “Player script” : LE D test.
Check matrix scanning at pin 36 and 37: see test instructions.
Check matrix scanning at pin 26,27,28,29,30,31,32,33.
Diagnostic software “Player script” : K e yboard t est.
Check supply voltages
The display pcb uses a 24V stabiliser(7112) in combination with a 10V zenerdiode(6102).
Check input voltage: at connector 1115-4: -40V 5%
Check output voltage at anode of Diode 6102: -10V 5%
Check stabilizer 7112 output (VKK): -34V 7%
Check +5Vstb voltage at connector 1115-3: +5V 5%
Check safety resistor R3117
Check +12V at connector 1115-1: +12V 10 %
Check filament voltage
A C vol tage is created via uP output pin 19 generating a 42kHz (duty cycl e 45/55) square
signal.
Check frequency : 42kHz 10%
Chec k buffered square output at emitter of transistor 7105; low level: 800mV, high level:
10.7V
Chec k DC decoupling: check RMS voltage between FIL1 and FIL2 lines:
3.9Vrms<Vfil<5.2Vrms
The Vfil_DC level at kathode of diode 6101 should be –25.8V 10%
Check oscillator frequency of 8MHz at pin 8 of IC7104
Check reset circuit around transistor 7108: see t est instructions of reset circuit.
