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.
•
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.
Parts face side:
Parts on the parts face side seen from
(Component Side) the parts face are indicated.
•
Indication of transistor
•
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
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
•
Waveforms are taken with a oscilloscope.
•
Circled numbers refer to waveforms.
•
Signal path.
F
: AUDIO (ANALOG)
J
: AUDIO (DIGITAL)
E
: VIDEO
•
Abbreviation
CH
: Chinese model
CND : Canadian model
KR
: Korean model
TW
: Taiwan model
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.
Note:
Les composants identifiés par
une marque
0
sont critiques
pour la sécurité.
Ne les remplacer que par une
pièce por tant le numéro
spécifié.
•
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
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.
•
5
: fusible resistor.
•
2
: nonflammable resistor.
•
C
: panel designation.
