Hi XenoSov to clarify … your friend plug the 110V range adapter into 230V outlet and power it on ? if so ….most prob the adapter has been blown, but i guess the keyboard should be fine. well, either to purchase a replacement power supply adapter, from casio, which i recommend. else, if you want to try…. you can open up the defective adapter and try repairing it.
