Why is there no sound coming from my LG SR72BR-A?
- A
  Alexander DixonAug 14, 2025
  There could be several reasons for the lack of sound. First, check that the speaker wires are properly connected. Ensure that the MASTER VOLUME isn't set too low and that the MUTE button is not activated. Also, verify that the selected decoding mode matches the input signal format and that you've chosen the correct input source. Double-check the connections between all components. If you are playing a file in PC-LINK mode, try executing the media player again.

Why is there no sound from the surround speakers on my LG Stereo Receiver?
- C
  Christopher HarrisAug 31, 2025
  If you're not getting sound from the surround speakers, first check that the surround mode is enabled and not set to normal stereo mode. Make sure that both the MASTER VOLUME and surround level are adequately adjusted. If you are using a monaural source, switch to a stereo or surround source. Finally, ensure that the surround speaker setting is not set to “NONE” and select the desired surround speaker setting.

Why can't I receive preset stations on my LG Stereo Receiver?
- A
  Alexandra WalkerSep 3, 2025
  If you are unable to receive preset stations, it may be due to an incorrect station frequency being memorized. In this case, memorize the correct station frequency. Alternatively, the memorized stations may have been cleared, so try memorizing the stations again.

  If you're not hearing sound from the front center speaker, it might be because Dolby Virtual or normal stereo mode is selected. Try selecting the desired surround mode. Also, check that the MASTER VOLUME and center level are properly adjusted.

Why is there no sound from the surround center speakers on my LG SR72BR-A?

  Heather MonroeSep 10, 2025
  If there is no sound from the surround center speakers, the input signal format or the current surround mode might not support the 6.1 surround. Under the proper situations, perform the 6.1 surround playback. Also, ensure that the MASTER VOLUME and surround center level are not set too low.
