 The prior observation that it occured with improperly seated connector
though points to "bad contact" as a suspect and corrosion may not be
confined to one connector although it may be more likely outside than inside. 
If it occurs due to a "bad ground" or something
in common two cables could produce similar symptoms. Of course there is
an issue of if the failure modes are even related. Basements tend
to be damp and inoxuous corrosive gases may exist too. Or someone
plugged it a lot in both connectors and made it more vulernable
to corrosion. Or something spilled on the outside and got
both. Curious though how the metal looks.
