you sure its the port? have you tried other add devices? On recap did you clean the board from goo?

might have to remove Q3 and clean the pads... and clean the legs of Q3, solder back down, as the cap goo spills all into it,

look at the pads/ traces as well, do a continuity, rot in this area causes this issue.

if you get too frustrated and give up ... no fear... Ted Hodges in Denver has a stack of these that go from the floor to the ceiling and probably most still work. He would probably send you a board for 15 bucks plus return shipping. Shipping to you there is cheap! $13.10 large envelope.
