Humming, buzzing or rattling noise heard from product | Bose Solo 15 Series II TV sound system
If you hear an unexpected noise from your product:
Try the following:
Be sure the rattling noise is not something on or near the system.
A loose item on or near the system may be vibrating when certain frequencies or volume levels are played. Secure any loose items or move the system or items to another location if the system sound is causing nearby items to rattle.
Be sure the system is set up properly and all connections are secure.
A connection may have come loose or may be connected incorrectly. For more info, see Setting up your product.
Disconnect the coaxial cable that comes from your wall to a device, then check if the issue stops.
Find the coaxial cable that is coming into your house, then isconnect it from the first device to which it connects. This is typically the twist-on connection to your cable or satellite box. If the noise stops when disconnected, purchasing a coaxial ground loop isolator should help. The coaxial cable will plug into the isolator, then the isolator will connect to the device.
Try connecting a different audio device.
If available, connect another audio device using the same cables and connections to determine if the issue is related to the first device or its settings.
