Cable TV causing system ground problems!

After responding to another thread about powerline products. ..I wanted to post what you might call a warning...or at least a "heads-up". Cable feeds...be they for TV or cable internet..or FM, can cause real problems for your stereo. The ground on cable can have DC and other problems..that if connected to your system through interconnects from unit to unit, or to the AC can cause you to go searching for a cure. The real cure is to keep cable feeds out of your system and your systems AC.

It does, and you're right. I am not a big TV fan..and am a big music fan..so I have just kept the two seperate.

Sfbaydude: I was speaking of cable TV/internet/FM..but not the 75 ohm coax lead from an external FM antenna. It is good that your cable TV input is not causing any concerns with your hi-fi system. Cable TV need not have ground concerns...but often does..and if it does, and your TV is connected in some way to your audio system..it will cause sound quality concerns. With anyone, the easiest way is to find out is just disconnect the cable (and all TV related items/cables) from you audio system..and listen. If your system sounds better with the cable/TV components disconnected..then there is likely a cable TV-ground concern.

I think some of the suggestions above are worth the try.. It seems that the ground form the Cable TV feed is usually the concern...usually DC voltage on the Cable ground. If you look at the info that comes with the Monster power strip series...like the model HTS-2000., they give some excellent information on the subject... It appears that Mr. Marsh and Monster are very aware that Cable TV presents real problems for audio systems...
