Your hardware has a problem. It has to be fixed by the replacement of some components. This is done here in Grenoble. You can ask Tomeso to handle your machine and they will likely contact our support team, or you can directly open a case on the Arturia web site. Then we'll organise the return of your machine here (your machine will be picked up by UPS), we'll do the reparation, and send it back to you (UPS again).
To open a case goto the support page and click on "3-Request specific Technical Support".
