Note on Schematic Diagram:
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 
 and 
1
/

W or less unless otherwise
specified.
f
: internal component.
• C
: panel designation.
Note: The components identified by mark 
0
 or dotted line
with mark 
0
 are critical for safety.
Replace only with part number specified.
• A
: B+ Line.
• B
: B– Line.
• H
: adjustment for repair.
Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : DVD PLAY
: Impossible to measure
Voltages are taken with a VOM (Input impedance 10 M
).
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.
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.
