Hello, I have purchased a Soundbridge Radio and have used it for two years or so without problems in the US; we recently moved to Germany and it has worked well here with a plug adaptor (not power converter, it was running with local 220V) ... now it doesn't start any more. Is there a fuse I could check or something? The light just stays dark. Any help is appreciated. Thanks.

Sorry to hear that your Soundbridge Radio doesn't seem to power up.
Though according to this thread, it isn't uncommon that these kind of devices die over time.
Since Roku stopped selling these devices and dropped support as well, you cannot ask them to get it repaired.
Though, some user on this forum might help you.
You can send user Burkhardi a PM (US), or user g0pkh(UK).
It is known that they helped many other here to get their Soundbridge Radio repaired.
