For schematic diagram:
• 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, be-
cause it is damaged by the heat.
• All resistors are in ohms,
erwise specified.
kΩ : 1000Ω, MΩ : 1000kΩ.
• All capacitors are in µF unless otherwise noted. pF : µµF 50V
or less are not indicated except for electrolytics and tantalums.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
2 : nonflammable resistor.
•
5 : fusible resistor.
•
C : panel designation.
•
• f : internal component.
C : adjustment for repair.
•
U
• : B+ Line.
V
• : B– Line.
• Circled numbers refer to waveforms.
• Voltages are dc between measurement point.
• Readings are taken with a color-bar signal on DVD reference disc
and when playing CD reference disc.
• Readings are taken with a digital multimeter (DC 10MΩ).
• Voltage variations may be noted due to normal production toler-
ances.
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.
