Korg 01w Malfuction

[Ben Bol]

Hi,
I have a Korg 01w that uses 220 volts, but I mistakenly plugged it into a 110 volts outlet. It produces no sound now and some of the letters etc doesn't appear on the screen either. The midi function still works though. Could anyone please tell me how to repair this. Also I dont know where the sound IC is. Maybe I could replace it. If there are any repair links related to this, kindly send it please.
Thanks,
Ben Bol

That's quite strange - it's usually the opposite (plugging 110V gear into 220V) that fries things....
