6-7. 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.
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• Indication of transistor
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

Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and

4
W or less unless otherwise
specified.
• 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.
no mark : TUNER
(): VIDEO 1
•Voltages are taken with a VOM (Input impedance 10 MΩ).
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 : TUNER
J : AUDIO (ANALOG)
c : AUDIO (DIGITAL)
E : VIDEO

AUS: Australian model
CH : Chinese model
KR : Korean model
MY : Malaysia model
SP : Singapore 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 portant le numéro
spécifié.
