Question about Televison & Video
There's a very distracting hum/noise when any audio plays from the tv. The hum goes away when muting, and when the volume is at zero. The hum at level one on the audio graphic display is the same noise at any other level. My cable box does not have the ability to adjust volume, so it shouldn't be getting too much signal. Any ideas?
I used an extension cord with a ground connection. Three prong plug capable.
I connected the TV, cable box and dvd player to the extension cord and the hum disappeared.
Ground loop gone.

Does the hum occur when playing a dvd or only when watching tv ? if the hum occurs only when watching tv, i would like you to disconnect the cable line from either the wall or the back of the cable box and see if this hum disappears. if the hum disappears call your cable company. you have what is called a " 60 cycle ground loop ". hope this helps.
