It is power supply regulator problem. In the regulator circuit, DC 12volt from adapter is separated into +8V, -8V, +5VA, +5VD' Some causes when the unit hang / frozen is one of the existing supply voltage is drop. In general, +5V. Also check the adapter voltage, if still normal and the current is sufficient. Adapter must have DC12volt and current of at least 3 amperes. It may happen, when the adapter is measured without load, it's read normal,12v. But when loaded to turn on the keyboard, many voltage decreases (lets say,between 8-10v). This indicates that the adapter is not good.

Take it back to where you bought it, and get it serviced, to clean the dirt-filled contacts.

NOT a fuse... thaat person knows nothing. There is something wrong for sure. Check if one of the buttons or keys MIGHT be stuck down (depressed). Sometimes the units check that all the control buttons are up and they don't really tell you why they fail to start. Beyond this a repair shop is in order.

Question edited for clarity. It is a known issue, you need an electronics engineer. https://www.google.com/search?q=korg+m1+distorted+output ..

No one knows the fuse type, but the details should be on the fuse itself. Then you can't get them from an electronics store or Amazon. The Service Manual is in the link. https://www.google.com/search?q=Korg+n364+keyboard+replacement+fuse ..
