Hello
You need an oscilloscope and the ability to handle the scope and the
ability to read schematics and pcb layouts.
To be honest: As long as you are not an "electronics guy" the chances
that you will destroy your CS are bigger than the chances that you will
repair it.
Just as simple example: one mounting rail of the cards runs supply
voltage. If you get the wrong contact between a device in the synth and
this mounting rail, you may blow a lot of things...
I am sorry, that I don't have better news for you.
