Congratulations to your successful repair! Voltages from PSU are +5 Volts and +/-15 Volts according to the Service Manual.

First thing I did was open up the 5000 and my CZ-1 and connect the CZ-1's powerboard to the CZ-5000 and voila - it worked, problem isolated. I then took the service manual and started measuring the powerboard and eventually found one connection on the board that wouldn't let any current flow - although it looked perfect. I simply bridged this connection with a wire and the Synth power on! > > You can find the service-manual on the web, it contains diagrams for all the boards. Actually I think it should also be relatively easy to completely replace the powerboard, all it does is provide different outputs of +/- 5V and 12V I think. > > Good luck! > Florian
