Connect the cd audio out to the line in or cd in on the marantz

You can connect TV RCA outputs to any line input e.g. tape, tuner, CD etc on the Marantz. If your TV doesn't have separate RCA outputs use a 'scart to RCA audio outputs' adaptor... TVs have a standard line output level compatible with most if not all hi-fi.

Please see my answers regarding the hookup of Marantz amps and preamps.

Can you please repost this download link? I have corrupt firmware on a marantz 1602.
Thanks!

First thing to do is replace the cable with a new high quality one. They can go faulty. If that doesn't work, check that you are outputting the correct signals from your devices, plus it is set to pick them up. If that doesn't work you might have a fault possibly on the TV.

the best soution is to connect them.hope this helps.kind regards,KJ

If what you meant was that the composite input is not working specially the video the fault is with the video processor in the input section. Unless a signal check is done the fault cannot be confirmed as it can also relate to a logic gate failure in the input selction.
