TV buzzes only on different scenes. Why?

Question

When the camera angle changes or when there is something like a show title it buzzes. As soon as the scene changes to something different, then it's fine again. I have RCA cables from UF switch to DVD player to TV. Coax from wall to UF switch of course. THIS ONLY STARTED DOING THIS RECENTLY, OTHER WISE I NEVER HAD THIS PROBLEM BEFORE. I did some wire switching the other night, trying to arrange my audio differently.

To make a long lesson short, the signal entering the tv is too high. The video signal is bleeding into the audio. That is what you are hearing. In order to fix this, you should try reducing the signal at the tv by inserting what is called a "pad" , also called an attenuator, in the coaxial cable. They come in different sizes. You can get them at an electronics parts supplier. Maybe look in the radio shack catalog or online. Most larger cities have such suppliers. Look in the yellow pages. The pad looks like a AAA battery with threads on each end. You will need a second short coaxial cable to install the pad. They are sized in decibles (db). You might only need a 2 to 4 db pad. If the picture looks bad then the pad is too big. Use the smallest one it takes to stop the buzz. Hope this helps.
