Kontrol S61 MK3 is not turning on since this morning. I was using it attached to computer directly. I then plugged it to outlet too but still it isn't turning on.
Try leaving the device completely unplugged (both power and USB) and then leave it unplugged for several hours. Not guaranteed to work but it has been seen that it can get a keyboard to behave.
Else then afterwards then try powering the keyboard again using a USB-C PSU that you are sure that is working and that is certified for USB-C PD and using a cable that is certified for power delivery also and then turn on keyboard power switch. Then try plugging the keyboard back into the computer using a another also working USB-C cable to see if the keyboard wakes up.
If it does not work then we will have to conclude that it's a hardware failure and you need to contact N.I. Support (all) for assistance and support options (depending if still under warranty).
In case that you need guidance contacting support : How to contact NI Support and How to get in touch with our Customer Care

Ok…Reporting back what's going on. First of, @PoorFellow thanks a lot for your reply and suggestions! I think I found the source of the problem.
Basically, couldn't hold myself opening the keyboard. The ribbon cable connector connecting the back module (with all connections - MIDI, USB-C, USB-Host, Pedals etc) was lose at the other end - the one that connects to main board. I figured out that the latch that basically holds the ribbon cable and doesn't let it fall off was not on lock position resulting of connection loss and eventually not feeding the keyboard with power.
It's working fine…for the moment. I really hope this was the issue. Wanted to share with you guys here in case someone is in the same situation.
All the best
