Note for Printed Wiring Boards and Schematic Diagrams
•
D_VIDEO and DSP boards are multi-layer printed board.
However, the patterns of intermediate-layers have not been
included in this diagrams.

Circuit Boards Location
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
Ω
and
1
/
4
W or less unless otherwise
specified.
•
f
: internal component.
•
2
: nonflammable resistor.
•
C
: panel designation.
•
A
: B+ Line.
•
B
: B– Line.
•
H
: adjustment for repair.
•
Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
– D_VIDEO and A_VIDEO boards –
no mark : VIDEO 1 mode
– Other boards –
no mark : TUNER
•
Voltages are taken with a VOM (Input impedance 10 M
Ω
).
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
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

Note:
The components identi-
fied by mark

are criti-
cal for safety.
Replace only with part
number specified.

Replacement of IC3601on the D-VIDEO board used in
this set requires a special tool.
•
The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
from that of conventional IC.

Replacement of IC3601on the D-VIDEO board used in
this set requires a special tool.
