Hi John; I did not go too much in details for my situation, always thinking that nobody would remember my setup "prior" to the problem: I have moved to a temporary rental apartment provided from the developer until the condo I purchased is built (they expect it around June), thus my "old" setup in the new conditions. The only change is that I don't have satellite tv anymore (not my choice) but Cox cable, at least until I move to my own place.
Also, from some research I did, it seems that cable signal is the problem. It appears like the cable signal causes a "ground loop" hum to my RC-1070 transmitted throught my TV. I called cable company as well and they were not that helpfull. The good news is I can play CD like before, can play dvd without noise but only if I unplug all cables going from the cable box to the TV. A little inconvenient you can see. The other good news is that I will not stay here forever (scary to think about another move!!). However, any advice on how to get rid of this hum would be appreciated.
