Korg Kronos Showing Updating The Panel Scan System

Please I’ve interchanged the main board with another yet it’s still the same thing, even the power too and both work on another Korg Kronos but this particular one kept showing same error.

Please guys what would you suggest I do here?

It’s a matter of urgency as keyboard has stayed 2yrs unattended to.


Might be cables or power supply issue similar to the M50 were some capacitors are getting old hence the voltage will not be stable or ripple free.

I would suggest to check the voltage oscilloscope under load or at leadt with a multimeter. This means the unit will be powered i.e dangerous if your are not familiar with these test. You could damage the unit or harm yourself.
