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.
kΩ = 1000 Ω, M Ω = 1000k Ω.
• 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.
• 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 10M
Ω).
• Voltage variations may be noted due to normal production tolerances.
When indicating parts by reference
number, please include the board
name.
Note:
The components identified by
mark
or dotted line with mark
are critical for safety.
Replace only with part number
specified.
