The sub is only blinking green meaning it has power but searching for the signal from the sound bar. About 15 seconds after you turn the sound bar off the sub will stop searching for it and turn red. If you want the red light off you will have to unplug it from it’s power source and of course plug it back up when you’re ready to use it again.
Sorry, there was a problem. Please try again later.The sub-woofer's LED blinking signifies that the unit is trying to connect to the soundbar. The sub-woofer's LED light should change to red once the wireless sub-woofer is in standby mode or the connection failed.
