Dean, There have been several suggestions that you might want to check out, a ground isolator that could be put between your cable and your TV, or someone suggested such a device on your patch cord. I have not seen one for patch cords so don't know about those. I bought such a device for a cable many years ago, but a search on Amazon might turn something up or perhaps others with more recent experience could suggest something specific.
