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.
