The LED on the subwoofer or sound speaker sometimes flashes, or experiences sound skip or noises.

    IMPORTANT: This article applies only to specific products and/or operating systems. Check the Applicable Products and Categories section of this article before starting these steps.

    This issue can occur if the main unit and the subwoofer are not linked. Try the following:

    1. If possible, move the subwoofer closer to the main unit of the home theater where it will not be directly blocked by any furniture, walls, or metal barriers.

    2. If the wireless access point (wireless router) that you use can switch between the 2.4 GHz and 5 GHz frequency bands, try changing the frequency to avoid interference from other wireless devices:

      • For the HT-ST9, HT-ST5, HT-NT3, HT-RT5, HT-ST5000, and HT-MT500: Try changing the wireless router to the 2.4 GHz band.

      • For the HT-CT780, HT-CT380, HT-NT5, HT-CT790, HT-CT390, HT-CT800, HT-MT300, HT-CT290, and HT-G700: Try changing the wireless router to the 5 GHz band.
