Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and

/
4
W or less unless otherwise
specified.
•
f : internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
• A : B+ Line.
• B : B– Line.
• C : adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
– DMB10, MIB01 and IO Boards –
no mark : DVD PLAY
∗ : Impossible to measure
– Other Boards –
no mark : TUNER
(): DVD PLAY
∗ : Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
F : AUDIO (ANALOG)
J : AUDIO (DIGITAL)
E : VIDEO
• Abbreviation
CND : Canadian model
RU : Russian model
SP : Singapore model
• Circuit Boards Location
• Indication of transistor
Note on Printed Wiring Board:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
•
f
: internal component.
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen from
(Conductor Side) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.
• DMB10 and MIB01 boards are multi-layer printed board.
However, the patterns of intermediate layers have not been
included in diagrams.
Note:
The components identi-
fied by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specified.
Note:
Les composants identifiés par
une marque 0 sont critiques
pour la sécurité.
Ne les remplacer que par une
pièce portant le numéro
spécifié.
