If the led on the subwoofer flashes slowly it is in standby mode and not paired to the soundbar. To pair the two unplug the soundbar and then plug it back in. Push and hold the PAIR button on the back of the subwoofer until the light goes solid. The two devices should now be paired. Hope this helps! Thank you, TCL Customer Support
Sorry, there was a problem. Please try again later.The blinking light indicates standby mode. Power on the TV and soundbar and the light should be a steady "on". See the FAQ section of the quickstart guide.
