Samsung TV & Audio HW-B650 3.0 Channel 330 Watt Soundbar with DTS Virtual:X and Bluetooth SUB LINK SOLID Error Fix: Subwoofer Connected — Blue LED Solid

Error code SUB LINK SOLID on the Samsung TV & Audio HW-B650 3.0 Channel 330 Watt Soundbar with DTS Virtual:X and Bluetooth means: Subwoofer Connected — Blue LED Solid. The wireless subwoofer's LINK LED is solid blue — the subwoofer is properly connected to the soundbar. This is the normal operating state. If you see solid blue but hear no bass: check subwoofer volume level (press the Woofer + button on the remote to increase), ensure the subwoofer is not in standby (STANDBY LED should be off when playing), and check that audio content contains bass frequencies. Some sound modes may reduce bass output. Subwoofer auto-powers on/off with the soundbar via the wireless link.
