Korg AX3000G jumping banks

Hi guys

My pedalboard started skipping registers by itself without anyone touching it. Can anyone help me to find out what it will be?

Tanks in advance.

Has any liquid been spilt onto the device, or have any switches, or the case been damaged? Does the bank jumping happen if the AX3000X is picked up and turned upside down or held in other orientations? Is the connection to the AC adapter in good condition? Does wiggling the power cable alter the behaviour?

none of that. sometimes it skips register when I press the pedals, other times without touching the pedalboard. it's completely random. I already replaced the motherboard and the problem persists.

Check the panel PCB and interconnects for bad/dry solder joints. Also check the PCB ground plane to case connections are good.

This sort of issue could also be induced by interference e.g. from a strong radio transmitter/cellphone nearby, heavy machinery/aircon startup/switchoff, highly charged static electricity environment, poor earthing of the amplifier/rest of the audio chain. Try using the padalboard in another location, remote from where it's being used now, even resorting to using vehicle power via a DC/AC mains converter, if it helps.
