Checks if the +15v comes well at CN01,02,13,16 Pin1

The dudes at the store took it back and completely replaced the old KLM-367 board with the leakage on it with a completely new clone KLM-367 board. I received it back in January with the new KLM board so I don't think this new issue is due to battery corrosion.

I do have some intermediate synth repair knowledge and I can definitely make my way around these things, I just have never really learned how to start going about troubleshooting. Any suggestions would be supersupersuper appreciated! We are leaving in a few days, and we have practice everyday until then!!!
