Hum when cablevision is plugged in to tv

I am trying to watch & listen to DVD's through stereo but get hum out of speakers when the cable tv is hooked up to back of tv. When I disconnect it the hum goes away. Never had this problem before until I moved to this apartment in big house. Any advice would greatly be appreciated.

Get a cable isolator from Audio Advisor ($99) or make your own for about $4.

The cable isolator is the same thing as a ground loop interrupter, which Radio Shack sells for around $10 or less. I installed one on my son's TV cable and it did the job just fine.

This is a common problem. You have a ground loop caused by your cable connection. You need to isolate The cable from your system. Audio Advisor caries a product from Mondial called the Magic Block. AT $99 it is expensive, but it works.

Enjoy,

I heard that you might need to check to see if your Cable connection Outside your house is properly grounded.

I called the cable company they are going to come out on the 3rd, hopefully they can ground it better or I will try some of your suggestions. Thanks very much Agon members for your help.
