Nords and humming issues

[loudness]

Since two years my Nord Stage Compact has unfortunately a humming issue very noticeable from the transformer.
My NS is 8 years old (it's the first model, revision C) but in mint conditions and only used at home.
I live in Italy (frequency: 50 Hz).

The humming is very pronounced on my Stage 3. It does not come out of the mains, but the whole thing hums and can be heard clearly from the other side of the room.

You mean like your whole board hums? I saw a few topics where people were concerned about noise from their new Nord, and almost always it was not so loud and it was coming from the new OLED displays. What type of hum is that one you hear (high, low frequency?). It can be current converter humming, I don't believe OLED is that loud so you can hear it from the other side of the room.

There's a way to tell if it's the oled or not: if the hum/buzz gets louder as more pixels are lit, then it's the oled. For example, try opening any menu and focus on a page with lots of pixels lit. You should be able to tell the variation in the buzz loudness.
