I've had a similar problem with my Harmon-Kardon A402 amp.  The same
problem occurs with Harmon-Kardon A430 amps, according to the technician
who worked on my amp.  All I needed to have done was have the switches
and contacts cleaned in the amp.  A friend tried using freon to do the
job, but it didn't work.  Supposedly, there's some new chemical that
not only cleans the switches, but also provides some level of
protection to lessen the chances of the problem reoccurring.
