Welcome
Sorry to hear that dude but I'm sure you are aware it could be literally anything. No one is going to know what's wrong with it without opening it up.
My advice would be to raise an official ticket through Arturia, they''l probably be able to tell you where to send it for repair. This is primarily a users' forum, not an official communication channel with Arturia staff.
Good luck getting it sorted. Sh-t happens doesn't it.
