True True.  My friend is in the (very expensive) high end electronics
repair business.  He fixes $10,000 amplifiers, and $5,000 CD players.
Anyway he told me that nine times out of ten when a customer has sprayed
most of the easily available (Radio Shack etc) contact cleaners into his
unit, he is in for a very expensive repair.  Most of the time spend on
aforementioned repair is removing the contact "cleaner" which has left
conductive residue on the circuit boards and generally "gummed up the
works".  Reclean all those connections with isopropyl alcohol or
trichlorethylene and the problem might just disappear.
