cable hum after thunderstorm.........


Hi all,
Had Thunderstorms roll through early today and now I cant get the hum to go away from my cable, if I pull the feed from the wall it goes away, is this a box issue or something outside?, I rebooted the box several times with no help, could a ground breaker for the cable from Radio Shack be the answer (this has happened before but went away., thanks

I live in an old house and have problems with the cable creating a hum with storms also. My cable originally hummed all the time. I reported a ground problem with Time Warner. Time Warner came out and attached the outside cable box ground to the main house ground. This fixed my hum problems except for when storms occur. I hope somebody will have an answer on this thread.
I guess I should add I live in a rural city in Texas without a basement. My house ground is a 8 foot copper ground rod with a heavy copper wire running from the breaker box to the copper rod.
