Prophet 08 module don't respond to midi

[Plym]

Hi.

Over night my P08 module just won't respond to incoming midi - the voice LEDs do not light up either. I've checked all settings in the global menu (different midi channels), tried different midi cables, different sequencers and keys as well. No luck. Occasionally one voice or another will light up and make a sound, but I can't seem to recreate it. That has so far only occured while my Cirklon is sending note data.

I've searched the forum and there's some cases that sounds kind of like the same. I'm worried this is a hardware problem..

Any tips?
