Troubleshooting

Sometimes the two devices may not connect even after trying automatic or manual pairing. Here are some of the approaches you can adopt to try and solve the issue;

  • Ensure that both devices are powered on: Sometimes you may have forgotten to power on one of the devices. An off LED sign on your subwoofer implies the device needs to be powered on.
  • Double-check if you are pressing the correct pairing buttons: Sometimes you could be pressing the power button instead of the pairing buttons. Be sure to press the correct pairing button.
  • Move the subwoofer closer to the soundbar during pairing: Apart from improving sound quality, it could also help the two devices to connect.
  • Ensure there are no obstacles preventing the pairing: Eliminate anything that might block signals affecting the connectivity.
  • Try turning the volume down: For some reason, subwoofers tend to connect to soundbars more effectively when the soundbar volume is low.
  • Unplug both devices for some minute: Like humans,l devices tend to get exhausted hence need a restart. If none of the above approaches tend to be resource, unplug the two devices for at least 5 minutes and plug them back.
  • Consult your LG soundbar’s user manual for specific troubleshooting steps: As mentioned previously, different LG Soundbar models may have different pairing procedures. Be sure to consult the specific LG model user manual to understand the specific user troubleshooting steps.

Must have tips when you are pairing an LG Soundbar with Subwoofer

Having understood the steps you need to follow to pair an LG Soundbar with Subwoofer, you need several tips to avoid problems when undertaking the procedure. Some of these tips include;

  • Master both automatic and manual pairing: Be sure to master both approaches so that when the automatic pairing fails you can try the manual way. 
  • Eliminate all forms of signal interferance: Before you even get into pairing the two devices, eliminate signal interferences from baby monitors, microwave ovens, other speakers, and medical equipment. This increases the probability of a strong connection.
  • Ensure volume adjustments: Having a high volume set in the Soundbar may interfere with the connection. Ensure that the volume is lowest before you get started. 
  • Eliminate obstacles: There should be no obstacles between the Sub and the Soundbar. In fact, it is advisable to have both of them as close as possible. 15 ft apart is the most recommended but incase connection is still a problem, you can bring them close to 5 ft apart.
  • Use the Stop or Mute button in case of connection problems: When you face connection problems, be sure to disable the sub’s volume control and press the Stop or Mute button for a few seconds to make the two devices discoverable for connection.
  • Apply the power recycling procedures where applicable: In cases when the LED lighting stops flashing, try repowering the devices to solve the issue.
  • Confirm pairing mode before you get started: The Subwoofer should be in pairing mode before you get started. Press it for a few seconds to initiate the pairing mode.
  • Ensure power connection: Always make sure that both devices are connected to a power source. Even though the devices are wireless, they still need to be wired to a powersource.
  • If the connection problem persists, reboot both devices: If issues persist, perform a “power cycling” action by turning off both the subwoofer and soundbar, then turning them on again. This simple reboot can resolve various connectivity issues.

The wired method

This approach is easy and straightforward. For a wired subwoofer, you just have to run one or two wires straight to the back of your soundbar, already plugged in power. 

The approach is less used nowadays due its less convenience and restrictions.
