I'm an authorized service center for Marantz although I mainly work on vintage equipment, according to the manual the code your getting is for speaker impedance imbalance , but if you don't have speakers hooked to it then you have issues with one of the channels output stages, it may not be something you can fix yourself unless you have some fairly advanced electronic skills

Here is the entire service manual with lots of troubleshootnig ideas...Good luck!

I do not know the answer but I would check to be sure there is nothing on top of it and that it has adequate ventilation. Try pointing a room fan at it and see if the problem goes away. If not you may wnat to contact there service as it sounds like it is either overheating or failing.

The Sr 6003 is not HDMI version 1.3a. and, it's not upgradeable via a software patch. What has everyone up in arms over this issue is that it's "HDMI"'s fault not your manufacturer. All AV receivers pre 2008-09 have 1.2 or 1.1 which does not work. The problem is what's called HDCP compliant. It's the movie and dvd makers crying about copyright protection. All you can do is to run HDMI direct from your DVD, Cable Box, etc. to the TV, then run Digital Coaxial or Optical to your receiver for audio. I know this is NOT what you want to hear! sorry!. We all have this problem! Hope this explains it for you. If you want more "Techno" on this issue, post a comment and I can get you anything you need.
