Hi Phil,

Yep your problem is loose solder joints on your analog board.

You can re-solder them yourself if you dont mind getting into
the mac.

Re-solder all the joints that are connected to the plastic connectors
as they all seem to crack and cause bad connections.

I have done it on several macs and it works every time.

Pay special atteintion to the outer joints as they always seem
to go first.  If you use a solder with about a 2% copper
the joints seem to last a lot longer.

The problem itself is with the different co-efficients of
expansion for the board and the connectors.  The thing
that gives way are the solder joints.

Hope that helps...
