Why does my soundbar keep turning off?

Soundbars usually turn off when they fail to detect audio signals. A faulty cable, loose connections and the volume being too low, can all cause a soundbar to turn off.

Turn up the volume too high while plugging your soundbar over a 3.5mm connection cable.

  •       Power consumption: Soundbars are logged into power-saving settings. When the soundbar is unable to receive an input signal or isn’t operated within a maximum of fifteen minutes, it will turn off. This feature can’t be alerted as it ensures less consumption of power by the device.
  •       Low volume level: Some soundbars are more sensitive to the input signal and may turn off when the sound volume is too low, or the soundbar is unable to detect the source of the device.
  •       Weak connection: If your soundbar is loosely connected to the TV, it may turn off.
  •       No AUX input: While using an AUX input, if no input buttons are pressed for around 8 hours, the soundbar will turn off.
  •       Faulty cable: If you are using an optical cable, the cable may be defective, which causes the soundbar to lose connection.
  •       Set-top box: If your soundbar is connected to a disc player or set-top box, the sound may be low, causing the soundbar to enter e sleep mode. Turn up the volume as high as possible to solve this issue.
  •       Defective soundbar: Your soundbar may face some technical defects or have worn out. Try contacting a technician if no remedies do justice to your soundbar.
