If your Marantz Amplifier has power but you're not hearing any sound, there are several things to check: * Ensure the speaker cables and input cables are properly connected. * Verify the INPUT SELECTOR knob is correctly set. * Make sure the VOLUME knob isn't set to the minimum. * Confirm the SPEAKERS knob is correctly set for your speaker setup. * Check the POWER AMP DIRECT button setting. * If the MUTE indicator is on, press the MUTE button on the remote.
