Use an oscilloscope to test if the
AF waveform at the output end
is normal or not (see the attached
figure 1).
Check if there is any voltage a
t
the power supply feet of the
power amplifier IC. If no voltage
is found, then check the voltage
part.
Adjust the sound volume to
a
moderate position and then ope
n
the menu AF output to check if i
