• Voltages are taken with a VOM (Input impedance 10 MW).
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 : AUDIO (ANALOG)
J : AUDIO (DIGITAL)
E : VIDEO
* Replacement of IC3601on the HDMI board used in this
set requires a special tool.
• The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
surface
from that of conventional IC.
