I kept on looking and found a capacitor at location 7C27 (220uF, 16V) that
had blown out the rubber plug at the bottom. So I replaced that. Now nothing
works. I know the new cap to be good.

Is it a double-sided (or worse - multilayer) pcb?
If the pcb designer used one or both of the capacitor pins as vias then you
could possibly have removed sufficient of the hole plating to lose e.g a power
or ground through connection.
