It’s possible, of course. Unfortunately, Sonos doesn’t offer a repair service, although there appear to be unauthorized repair places in the U.K. and maybe EU, you could do a search for them on the internet. Of course, once a device has been opened, it is no longer eligible for a trade in, so you’ll need to evaluate that as well. You could always call Sonos Support directly to discuss it, before doing anything else, to see if it needs to be repaired or replaced, or is a solvable issue.
When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.
Thanks Bruce, based in Australia so will see if they have a local support number.
You should be able to click on the link in my post, and if your browser is set to the Australian Sonos site, you’ll get the appropriate information.
In case you have an issue, here is a direct link.
