      If your Marantz Receiver has no sound and picture despite being powered on, first ensure that mute is off by using the remote control.

    Why is there no sound output from the surround speakers on my Marantz Receiver?
    • J
      Jeffrey MartinezAug 27, 2025
      If you're not getting any sound from the surround speakers, check that the speaker cables are correctly connected. If the Surround mode is set to STEREO, no sound will be output from the surround speakers, so select a different Surround mode. Also, ensure that 'Surround = NONE' is not selected in the SETUP mode; correct the setting if needed.

    Why is there no sound output from the center speaker of my Marantz SR4200 Receiver?
    • R
      Ronald SheltonAug 26, 2025
      If there's no sound from your center speaker, first ensure the speaker cable is properly connected. Check that the Surround mode isn't set to STEREO, as this mode deactivates the center speaker. If it is, switch to another Surround mode. Also, verify that 'Center = NONE' hasn't been selected in the SETUP mode; if it has, correct the setting.
