If you are having trouble pairing the LG s33a1-d subwoof, there are a few things you can try to solve the problem. First, make sure that your LG subwoofer is connected to your Wi-Fi network. If it is, you should see a blinking red light or a green-yellow light on the LED display.
Next, make sure that you have both the LG soundbar and LG Subwoofer in close proximity to each other. The closer they are, the better. If they are not, you should first try to remove them from their sockets and try again. Otherwise, the pairing process will be hampered due to the distance between them.
If pairing does not work, you can try to re-pair the subwoofer and soundbar with the help of a sound technician. If the LG subwoofer and soundbar are not compatible, contact the manufacturer for further assistance. If you have an LG soundbar, it is recommended that you pair it with the LG subwoofer for the best sound. The soundbar and subwoofer can work well together if you know how to connect them properly.
The LG Subwoofer should be within fifteen to sixteen feet of the LG Soundbar. If the subwoofer is too far away, the LG Soundbar will not work. If the subwoofer is connected to the Soundbar, the light should be green.
