Note:
• All capacitors are in
µ
F unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics and
tantalums.
• All resistors are in
Ω
and
1

4
W or less unless otherwise
specified.
•
f
: internal component.
•
C
: panel designation.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
•
A
: B+ Line.
•
B
: B– Line.
• Voltages and waveforms are dc with respect to ground un-
der no-signal (detuned) conditions.
• Voltages and waveforms are dc with respect to ground in
service mode.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
*
: Impossible to measure
no mark : DVD STOP
• Voltages are taken with VOM (Input impedance 10 M
Ω
).
• Circled numbers refer to waveforms.
• Signal path.

Note:
•
X
: parts extracted from the component side.
•
a
: Through hole.
•
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• Indication of transistor.
Caution:
Pattern face side: Parts on the pattern face side seen from
(SIDE A) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(SIDE B) the parts face are indicated.
Note: The components identified by mark
0
or dotted
line with mark
0
are critical for safety.
Replace only with part number specified.

IC103 is a written in and settled EEPROM. Supply with
a single article has not been carried out. In case you
exchange by DMB10 board, please put on IC103
currently used with the model again.
