W or less unless otherwise
specified.
•
f
: internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
• A : B+ Line.
• B : B– Line.
•Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : FM
(): OSD ON
•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 (FM/AM)
L : VIDEO (AUDIO)
I : VIDEO
J : DVD (DIGITAL)
c : CD (ANALOG)
• Abbreviation
CND : Canadian model
E2 : AC 120 V area in E model
for printed wiring boards:
• X : parts extracted from the component side.
•
f
