Note for Printed Wiring Boards and Schematic Diagrams
Note on Printed Wiring Board:
X : parts extracted from the component side.
Y : parts extracted from the conductor side.
: internal component.
f
: 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.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.

DIGITAL, DSP, ILINK, D-AMP, FILTER-L and FITER-R boards
are multi-layer printed board.
However, the patterns of intermediate layers have not been
included in this diagrams.

Note on Schematic Diagram:
All capacitors are in F unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics
and tantalums.
All resistors are in
specified.

f
5 : fusible resistor.
2 : nonflammable resistor.
C : panel designation.
Note:
The components identi-
fied by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specified.
A : B+ Line.
B : B– Line.
H : adjustment for repair.
Voltages are dc with respect to ground under no-signal
(detuned) conditions.
(When measuring circuit that used "VIRTUAL GND" of
the VIDEO, S-VIDEO, MOTHER COM, D-AMP, FILTER-
L, FILTER-R, SP-TERM COM, HDMI POWER, FAN, 12V
and DC boards, ground it from CN3804 pin 2 on the
MOTHER COM board.)
– VIDEO, S-VIDEO, HDMI POWER boards –
no mark : VIDEO 1 mode
– Other boards –
no mark : TUNER
( ) : VIDEO 1 mode
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.
Circled numbers refer to waveforms.
