(The other layers’ patterns are not indicated.)
For schematic diagrams:
•
All capacitors are in µF unless otherwise noted. pF : µµF.
50V or less are not indicated except for electrolytics and
tantalums.
•
All resistors are in ohms, 1/4W (Chip resistors : 1/10W)
un-less otherwise specified.

Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum capacitor,
because it is damaged by the heat.
•
All variable and adjustable resistors have characteristic
curve B, unless otherwise noted.
•
: non flammable resistor.
•
: fusible resistor.
•
: panel designation.
•
f
: internal component.
•
: adjustment for repair.
•
: B+ Line.
•
: B– Line.
•
Circled numbers refer to waveforms.
•
Voltages are dc between measurement point.
•
Readings are taken with a color-bar signal on DVD refer-
ence disc and when playing CD reference disc.
•
Readings are taken with a digital multimeter (DC 10M
Ω
).
•
Voltage variations may be noted due to normal production
tolerances.
Caution:
Pattern face side:
Parts on the pattern face side seen
from
(Side A)
the pattern face are indicated.
Parts face side:
Parts on the parts face side seen from
(Side B)
the parts face are indicated.
When indicating parts by reference
number, please include the board
name.
Note:
The components identi-
fied by mark
or dotted
line with mark
are criti-
cal for safety.
Replace only with part
number specified.
Note:
Les composants identifiés par
une marque
sont critiques
pour la sécurité.
Ne les remplacer que par une
pièce portant le numéro
spécifié.
