Re: TV throwing back electricity to my cable
You stated that the cable is separate from the electrical ground. That may be causing a difference in ground potential allowing the electricity to try to ground via the coax plant. |

| Hi claydean,
Thanks for the reply -- I'm not sure if that's the problem. I plugged the TV into an outlet on a different circuit in my house, and there's no problem with stray electricity coming out of the TV through the cable. And the lower channels that were "snowy" due to electrical interference are now just fine.
I've been discussing this over on another forum, too: »TV seems to be throwing electricity back to the cable
Anyway, if you've got any other ideas, I'd love to hear 'em!

| Use an outlet tester, make sure the outlet is wired correctly.

Where I was going is that it appears that the outlet was using the coax plant to ground. This can happen with poorly wired outlets, poor grounds, or difference in ground potential. The phone, coax, and electrical should always have a common bond to common ground to prevent ground loops. |

Best answer right there...
Your cable system should be bonded to the electrical ground |

Wilmington, DE |  The cable at my old house was bonded to the gas meter when I moved in. They changed it soon as I pointed it out to them. Talk about scary! |

Bonded to a gas line right, Somebody thought it was a water line. |

I know of two techs who DRILLED through it... one a gas pipe in the wall, the other a gas meter on the other side of the wall.
Not sure how, I wasn't there, but I figured they'd stop drilling if they hit metal... guess not. |

I've seen catv "bonded" to the heating oil inlet pipe a few times.. one tech (who is no longer employed) thought it was ok to strip 5" of the ground wire and stick the wire into the ground..
I could go on of the ingeniously stupid things I've found on QC's.. |
