WARNING
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.
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 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.
ESD
D
WARNUNG
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.
NL
WAARSCHUWING
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.
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 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.

BRIEF INTRODUCTION OF THE AV BOARD
The AV Board consists of the following features :
a. IC CS42418
IC CS42418 which includes functions such as ADC and DAC, sound control, volume control and muting function.
Sound features such as DSC are controllable via I2C Bus from the SD6.1 module.
The IC caters for 2 channels analog input via a 4 stereo channels MUX HEF4052BT.
The MUX multiplexed between Aux In, TV In, Tuner and Mic In.
Input networks are included to provide appropriate attenuation for various sources.
b. SCART(for /01 and /05 versions only)
SCART input/output for audo/video (output only) connection to TV.
c. LINE OUT
Line out with cinch socket for connection to external amplifier.
d. TV IN
TV In cinch socket for connection to external TV input.
e. Y/Pb/Pr (not for /01 and /05 versions)
Y/Pb/Pr component video output with cinch socket for connection to TV.
Progressive Y/Pb/Pr is selected through RC.
f. IC M62320FP
IC M62320FP which served as additional I/O port.
g. DIGITAL IN
Digital In with cinch socket for connection to Digital Out of other audio equipments.
The Digital In source is fed to the SD6.1 module for audio decoding.
