f
: internal component.
• 5 : fusible resistor.
• C : panel designation.
• A : B+ Line.
• Power voltage is dc 10 V and fed with regulated dc power
supply from DC IN jack (J401).
• Voltages and waveforms are dc with respect to ground in play-
back mode.
no mark : DVD PLAY
: Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.

* Replacement of IC902, IC1002 used in this set requires a
special tool.
• The voltage and waveform of CSP (chip size package) can-
not be measured, because its lead layout is different from
that of conventional IC.
