I have a separate receiver for HT. When that receiver is turned on, I have a similar issue, regardless of whether the TV or cable box is. When it's not, I don't, regardless of whether the TV or cable box is. If you don't have a separate receiver, you probably have to ground your TV, cable box, or both.
Ground Loop in HT system???...HELP
I have a reoccuring hum coming thru my amp and cd player about every 5 to 7 seconds.
My equipment is McIntosh mc205 and mx136,Naim Audio CDX,Oppo 93,Furman Elite 20PFi,time warner cable box and Pioneer Elite Pro 110fd plasma tv. All on a dedicated 20 amp line.
I've narrowed it down to the tv. When the picture's on the hum is there, when tv is off...no hum. It's not the cable box either.
I had luck with an extension cord for the tv-plugged it in across the room...hum is gone. Also used a smaller LCD tv set up with in the HT and no hum. Is it my HDMI inputs on the tv? I'm lost and no one seems to the any answers. Any help would be very much appreciated. Thanks guys
