Try this and let me know. First unplug the unit. Plug it back in. When you first push the power button, you should hear 1 click followed by another withing 5-20 seconds. My guess is that you don't hear the second click. Am I right?

You have this backwards. Applicable code(s) will be found in the remote control, if it is compatible.

It's time to take it to an electronics tech. Something inside it has died, blowing the fuse. This isn't a do-it-yourself project.

Not too difficult. On the back on the far left are two phono sockets marked CD, you can simply get some decent RCA to RCA leads and connect them via that.
Some CD players have either an RF lead or digital output socket. Suitable leads can be connected to the digital in sockets on the Marantz.
