Hard to say what's wrong with it, but do you have any test equipment? I'd
start by disconnecting the internal power supply from the rest of the synth,
then measure the output to see if it's got the voltages that are supposed to
be there. If that part is ok, I'd reconnect the synth and start testing one
module at a time. If the VCO isn't working, do you have any other modular
gear that you can patch into it? You could patch an external VCO into the
VCF or VCA to see if you get an output.
Often old electrolytic caps dry out and die. Power supplies usually have
several (often larger ones), so that is a good place to start.
