"Hi,

Does it power off if you hold the Standby/On button for more than 3 seconds? This is a force release condition.

Here’s a link to the service manual which may be of some help.

It shows in the booting flowchart on p.55 that the power on process is processor controlled, much like a computer so I would imagine that the power off process using the Standby/On button would be the same, processor controlled I mean.

Try resetting the keyboard and check if this resolves the problem in case it is corrupted data somewhere that is the cause. (see image below)

If still no good, if possible try updating the firmware in case it is corrupted."
