  Ashley JohnsonSep 12, 2025
  If your Sharp TV has no sound, verify that all connections to other components are correct and the volume isn't too low. Ensure that 'Variable' is selected in 'Output Select'. Check if you've accidentally muted the TV using the remote. Also, examine the audio output settings of any connected external equipment to ensure it's not muted or set too low. When using HDMI, you might need to configure the audio output through the HDMI cable. For PC connections via HDMI, ensure the PC's audio output is correctly configured to a compatible format like PCM or Dolby Digital.
