merry christmas everyone dedicated lines..????


hello. i have 2 dedicated lines, one for the tv and one for audio. i am having some difficulty with my AC. i'm trying to address a ground loop hum due to my cable service. however that is not my question today. how it possible, with dedicated lines, that if my wife uses a hairblower in a bathroom three floors up i get hum bars across my t.v. and a terrible buzz through my stereo. i suspect the lines are not actually dedicated. any insight would be greatly appreciated. thanks, d.

thanks everyone. i will try all your suggestions, work on the lines myself and start tripping breakers. i'll do like a couple rooms a day, slow and steady will win the race! anyway warren, i have the tv, dvd, and cdp, in one outlet and the anaolgue gear in the other. i think that is the correct way to set-up, yeah? thanks again all, will post results...
I didn't read your post carefully. Two dedicated lines, I see. veddy good. you're on your way to electric nirvanna.
