troubleshoot no power issue

[bradbeier]

Hi, I'm getting no power to my Yamaha SY77 when I press the power button.
I've put a multi-meter on the switch, as well as each fuse that shares that circuit board with the switch. Everything seems fine so far.

Any ideas of how to troubleshoot this problem from this point forward?

Thanks,

Brad

Have you checked the power lead, There could be breaks in the internal wires.
