My only reason to think that the keyboard isn't damaged is that I can get it to work in the way it should, but it's just not consistant. I could be wrong though...
It is encouraging that you can get it to work sometimes. Please verify that you get full stereo when you listen at your Nord. If this is the case, it's possible the Nord's electronics are fine. --I don't have access to the Nord schematics, but I expect the Nord employs a circuit to detect when the monitor plug is inserted. This circuit might be damaged and affecting the behaviour of the monitor input.
It's possible too for the Nokia or Asus to work (to produce correct stereo), but the extra Mic contact introduces an unknown into this, so it best and safest to avoid those for now.
The case that I expect to work is the MP3 player, with plugs fully inserted at both ends. If you observe this case distortion-free, in stereo, but intermittent, then it might only be a mechanical problem with the Nord's jack or still a cable problem. If possible, try a different MP3 player.
If it is a mechanically-damaged or improperly-soldered jack in the Nord, the repair is quite simple (re-soldering or replacing the jack).
Please let us know what you find.
Best of luck,

So, after excessive testing with 3 cables,2 laptops, MP3 player, home stereo, 3 smartphones and home PC with Creative X-Fi Titanium sound card I found what was causing the problem and inconsistency. So, the problem was caused by the headphones that I connected to the headphones jack on my Nord. If it is a headset (with a mic), I get that inconsistency described in the previous posts.
I totally forgot that I have a mic on my Razer Electra headphones ( Before you judge me, I'm a student and those were the only headphones I had at the student's home ) since you get two cables with them - one with the mic on the cable and the other one without it, obviously. As soon as a saw the 4-pin connector on the end of the headphones cable, I felt stupid. I plugged in the different cable to the headphones and did testing with all the devices and it works as it should, so... no damage was done! (I guess)
I got the problem solved, which is good, but those 3.5mm jacks with 3-pins, 4-pins, stereo, mono, mic + sound mono, mic + sound stereo (or whatever) are blowing my mind and I had some problems with them in the past, but didn't really care as much. Thanks for that picture above showing what each pin on a jack does, I'll try to remember that. If you have any tips regarding those 3.5mm bastards when working with instruments, I would be grateful. I guess I should just always use a standard 3-pin stereo cable (with no mic) then?
Thanks again,
Rudolf
