Pull the conector out of the digitone. Turn it on and off. Then put the power conector at the back of the digitone back in and try turning it on again.
If that didnt help then there was nothing else you could try. I had the same thing with a digitakt except that unplugging it at the back fixed the problem. I sent the digitone back too but thats because I discovered that FM isnt for me. Live and learn.
It more like 4ct, but still annoying. The elektrons are so well constructed that only a small part has to be replaced.
Had that on my MD, but it was an easy repair.
This just happened to my dn keys. it sucks to have randomly happen, only having had like 5 or so months out the box. Without continuously trying to flip the switch and try different power outlets, which seems futile, just gonna hope support comes through.
I can also recommend having an UPS or power conditioner all the time before your beloved and pricey gear. Might saves just the PSU but it’s worth the time it saves too…
