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.

Have the same issue

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 ..

If you contact Korg, they can send you a dowloadable link to burn the software to a disc.

up to you if you ant to spend the money to have it diagnosed and repaired

$213 or take to an electronics service technician to diagnose which part got damaged and replace the component/s. https://reverb.com/au/item/69569832-korg-n364-n264-x2-x3-workstation-power-supply-board-assembly-part-klm-1633 https://www.google.com/search?q=Power+supply+board+of+Korg+X2 ..

The buttons are damaged or defective. Replacement may be the only answer.

Might be a case of opening up the M50 as the previous poster did and wiggle connectors and components until the sound is affected. If you have some electronics experience, it should be fairly easy to figure out which board to investigate.

Try resetting the software.

I think that the entire touch panel and everything has to be replaced then fully.

Initialization: Hold Page + and Page - while turning it on. Preload: Global Screen 5A, then select "OK". ROM Check: Hold Edit and Global/Multi while turning it on.

Maybe because the battery needs to be replaced.
