Greetings all:
I am working, without a manual, on a JVC AV35750 with an intermittant
audio
problem. Sometimes the audio is good, sometimes it pops and buzzes as
if
you were connecting audio cables with the volumn turned up. It appears
to
have good audio on the jungle, IC201p54 at all times. The problem
appears
to be between the jungle and the audio IC, but I have been unsuccessful
in
pin it down. Flexing the board seems to make no difference. Replaced
the
audio output IC, removed and tested the caps around it.
Any ideas?
Thank you for your time and consideration.
