My 2 week old Sonos Arc died yesterday. Used it during the afternoon without issues and at night, when I connected the TV again, it not longer registered. Followed all the instructions ( rebooting the router, reconnecting the power cable, etc.. ) and nothing worked. The Sonos Arc is completely dead - touching the buttons doesn’t do anything. 

Sub + Sonos One SL are still powered on and register when I touch the buttons - no power issues at all. 

All my home theater devices are connected to power surge protected extension cords. The TV is connected to the same extension as the Arc - so is the sub. All are working just fine. My Sonos Arc was a refurbished model - maybe it was a dud? 

Tried to reach the support team with no success - Live chat says no representatives are available and phone number for Portugal is disconnected.

How can I get help? I can’t seem to even find an e-mail contact. I’d like to active my warranty as soon as possible so I can get a replacement. 

Thank you.
