SUB LINK BLINK
Samsung TV & Audio · HW-B650 3.0 Channel 330 Watt Soundbar with DTS Virtual:X and Bluetooth
The wireless subwoofer's LINK LED is blinking blue — it has not paired with the soundbar. This is the #1 most reported Samsung soundbar issue. To manually pair: (1) place subwoofer within 3 feet of soundbar, (2) unplug both soundbar and subwoofer for 30 seconds, (3) plug in subwoofer first — wait for blue LED to blink, (4) plug in soundbar — LINK LED should turn solid blue within 30 seconds. If it doesn't pair: press and hold the ID SET button (small hole on back of subwoofer) with a paperclip for 5+ seconds until STANDBY LED turns off, then power cycle soundbar. Ensure no other Samsung soundbar in range is stealing the connection. 5 GHz Wi-Fi routers very close to the subwoofer can interfere with the 5.8 GHz wireless link.
