- A: AnswerHi Faye! If you notice any disturbances from the speaker while watching TV, you can conduct a sound test on the television to determine if the disturbances originate from it. Not detecting any disturbances during the sound test could be attributed to an unreliable broadcast reception or a faulty external device linked to the TV, such as a set-top box, gaming console, DVD player, Blu-ray player, or computer. Please verify the device's connectivity status. If you encounter disturbances on specific channels, it might be due to an unstable broadcast reception.
