If your Marantz Stereo Receiver isn't powering on, ensure the power plug is correctly inserted into the power outlet. If it still fails to power on, the protection circuit might be active. In that case, disconnect the power plug from the electrical outlet, wait 5 to 10 seconds, and then re-insert it.
Why is there no audio output from my Marantz Stereo Receiver?
If you're not getting any sound from your Marantz Stereo Receiver, check the connections for all devices and the speaker connections. Also, make sure the audio device is powered on, the master volume is adjusted appropriately, and the mute mode is off. Ensure you've selected a suitable input source and input mode. Also, disconnect the headphones, as no sound is output from the speakers or the PRE OUT connectors when headphones are connected.
Why is there no sound from my subwoofer connected to Marantz Stereo Receiver?
If you're not getting any sound from the subwoofer connected to your Marantz Stereo Receiver, check the subwoofer connections and ensure the subwoofer’s power is turned on. Also, verify that “Speaker Config.” – “Subwoofer” on the menu is set to “Yes.” If “Front” and “Center” for “Speaker Config.” are set to “Large”, and “Subwoofer Mode” is set to “LFE”, no sound may be output from the subwoofers, depending on the input signal or selected surround mode.
How to set up DTS sound output on Marantz Stereo Receiver?
To enable DTS sound output on your Marantz Stereo Receiver, set “Decode Mode” on the menu to “Auto” or “DTS.”
Why is there no sound from surround back speaker on Marantz Stereo Receiver?
If there's no sound from the surround back speaker on your Marantz Stereo Receiver, set “Amp Assign” on the menu to “Normal.” Also, set “Speaker Config.” – “S.Back” on the menu to something other than “None,” and ensure the surround mode is set to something other than “STEREO.”
Why is there no sound from front height speaker on Marantz Stereo Receiver?
If there is no sound from the front height speaker on your Marantz Stereo Receiver, set “Amp Assign” on the menu to “Normal.” Also, set “Speaker Config.” – “Surround” on the menu to something other than “None.”
Why is my Marantz Stereo Receiver's power indicator blinking red?
If the power indicator on your Marantz Stereo Receiver is blinking red in intervals of approximately 2 seconds, it indicates that the temperature inside the unit has risen. Turn off the power and re-apply it after the temperature has sufficiently fallen. Also, reinstall the unit in a place with good ventilation. If the power indicator is blinking red in intervals of approximately 0.5 seconds, please use speakers which have the specified impedance or firmly twist the core wire in the speaker cable, and then re-connect it to the speaker terminal because the speaker cable may have shorted (is touching).
What to do if no video is output with HDMI connection on Marantz Stereo Receiver?
If you're experiencing no video output with an HDMI connection on your Marantz Stereo Receiver, start by checking the connection of the HDMI connectors. Ensure that the input source is set to match the connected HDMI connector. Also, verify that your TV is compatible with copyright protection (HDCP); if it's connected to a non-HDCP compatible device, video output may not work correctly.
How to fix Marantz Stereo Receiver remote control when it is not working?
If the remote control unit is not operating your Marantz Stereo Receiver, replace the batteries with new ones. Ensure you operate the remote control within 7 meters and at an angle of within 30°. Remove any obstacles between the unit and the remote. Verify the batteries are inserted correctly, checking the q and w marks. Also, the set’s remote control sensor may be exposed to strong light; move the set to a location where the sensor isn't exposed to direct sunlight or inverter-type fluorescent light.
Why is my Marantz Stereo Receiver display off?
If the display on your Marantz Stereo Receiver is off, set “Display” on the menu to something other than “OFF.”
