Unplug the soundbar from the wall outlet and check where the two parts of the power cord connect.

What to do if your Polk sound bar stops working?
Welcome to Polk’s forum, sorry you’re having a problem. I believe the only thing you can try is to after switching off the AC power selectors on the soundbar and the subwoofer, then unplug the power supplies for both. Wait a few minutes then re-plug the power supplies and switch the AC selectors on.
