  If your LG Speaker System isn't working correctly, try turning off the power to both the unit and any connected external devices like your TV, Woofer, DVD player, or Amplifier, and then turn them back on. If that doesn't work, disconnect the power cord of the unit and the external devices, and then reconnect them. Keep in mind that previous settings may not be saved when the device is shut off.
