This is great news, for meI have a D50 here with the same issue. I had suspected the relays on the outputs. Plus broken sockets and sticky buttons. It was not loved.
So you've found that the joints were bad on the op-amp- but is it possible that the heat from the soldering iron gave a temporary fix to an internal open circuit in the chip? Doubtful I know, I can see from the pics that your soldering skill is perfect! Very nice job on SMD
