Ver. 1.3
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
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
specified.
• f : internal component.
• C : panel designation.
Note:
The components identi-
fied by mark 0 or dot-
ted line with mark 0 are
critical for safety.
Replace only with part
number specified.
New part of EEP ROM (IC1103) on the MAIN board
cannot be used. Therefore, if the mounted MAIN board
(A-1144-739-A, etc.) is replaced, exchange new EEP
ROM (IC1103) with that used before the replacement.
• 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.
