Sonos play 5 (gen1) blinking red light
bought a used speaker. When I got home and plugged it in it just starts flashing red. I have read that it’s due to not being connected for over 30 mins. As soon as powered on it starts flashing red. I have tried unplugging waiting 10 sec then plugging back while holding the mute button. Doesn’t do anything tried multiple times. Tried connecting straight to router with Ethernet cord can’t get it to do anything either. Took it apart and tried seeing if any burn marks on board it all looks good. Any help would be appreciated. Thanks
