Polk Magnifi One Turns Itself Off Every Couple Minutes

I am experiencing a problem with my soundbar turning itself off every couple of minutes. We do not have a TV with Bluetooth capability so it is wired. We have only had the soundbar for a few month and have never had an issue until last night. It is extremely annoying and we have checked all the connections. Any thoughts?

    Welcome one and all. Usually this type of problem is being caused by the incoming audio signal not being strong enough to prevent the automatic standby mode from activating. The cure is to raise the level of the source signal above the standby threshold.

    What is the "standby threshold" for a TV?

    Polk sound bar both for TV and bluetooth randomly and often just turns off. What do I do.

    That usually means the strength of the incoming signal is too low to prevent the automatic on/off feature from being triggered. The solution is increase the level of whatever is providing the source signal.

    My DSB1 Sound Bar is doing the same thing. Mine is also wired to the tv and about every 10 minutes, the sound bar turns off. It did not do this the first 3 weeks I owned it.
