I'm not 100% sure because I haven't had time to reorganize everything to test it but the most likely thing is the cables are getting outside interference from the other cables. Unlike digital where there isn't really anything that could interfere with the signal it's much different with analog where a host of things can screw with the signal. So it could be the quality of the cables insulation is letting in interference from the surroundings or the length of the cable might be too long for the power output of the system if you're using aftermarket cables. There's a few other things that can interfere with the signal but I think those are the two main ones. If you test and rule out outside interference then it might be the TV. Good luck, hope this helps.
