HomePod won’t power on

Hi all. So one of our HomePods won’t power on. It worked 100% yesterday and simply won’t power on today. No light on top and not showing in Home app. I’ve swapped power leads with our other HomePod which had no impact on either HomePod. Any suggestions about other possible fixes I could try would be appreciated. Would hate to have to recycle this great smart speak after only a couple of years of ownership
