1. Check the power source: Ensure that the power outlet the amplifier is connected to is functioning properly by plugging in another device to confirm if it's working. You may also want to check if the power cord is securely plugged into the outlet and the amplifier.
2. Reset the amplifier: Sometimes, electronic devices can experience minor glitches that can be resolved by performing a reset. Unplug the amplifier from the power source, wait for a few minutes, and then plug it back in to see if it powers back on.
3. Check the fuse: If the amplifier still doesn't power up, it's possible that the fuse inside the unit may have blown. You can open the amplifier (if you're comfortable doing so) and visually inspect the fuse to see if it's damaged. If so, you may need to replace it with an identical fuse.
4. Professional inspection: If none of the above steps resolve the issue, it may be a more serious internal problem with the amplifier that requires professional repair. In this case, I'd recommend reaching out to Marantz customer support or a certified technician to diagnose and fix the issue.
