Take a look at this drawing:
Terminal A goes to the next stage. When nothing is plugged into the jack, the signal from the mic preamp comes into terminal B, is connected to A by the contact inside the jack, and goes to the next stage.
When you plug something into the jack, the swinging arm breaks the contact; now terminal A is connected to the tip of the plug that's in the jack, so you're sending an instrument's signal to the next stage. Unplug it, and you should get the mic preamp signal again.
There's a good chance that the internal contact in the jack, which connects A to B when nothing's plugged in, is bad. Another possibility is that B has become unsoldered.
Peace,
Paul
