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
