SECTION 6
DIAGRAMS
For Schematic Diagrams.
Note:
• 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.
• 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.
•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.
no mark : DVD STOP
*
: Impossible to measure
•Voltages are taken with VOM (Input impedance 10 MΩ).
• Circled numbers refer to waveforms.
• Signal path.

For Printed Wiring Boards.
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:
Parts face side: Parts on the parts face side seen from
(SIDE A) the parts face are indicated.
Pattern face side: Parts on the pattern face side seen from
(SIDE B) the pattern face are indicated.
✩ New part of EEP ROM (IC103, IC706) on the DMB12 board
cannot be used. Therefore, if the mounted DMB12 board
(A-1148-813-A) is replaced, exchange new EEP ROM
(IC103, IC706) with that used before the replacement.
Note: The components identified by mark 0 or dotted
line with mark 0 are critical for safety.
Replace only with part number specified.
