I recently purchased a big screen TV and sound system. It's in my basement adjacent to my SD-1 and speakers.

Since the TV was installed, there has been a loud buzzing noise in my SD-1 speakers. I've isolated the source and it's a result of my video out on my SD-1 into the new TV. The SD-1 video out cable is connected to an RF modulator and the coaxial cable from the RF modulator is hooked into the coaxial antenna input in the TV. This worked fine on my old TV with no static. Any ideas are greatly appreciated.
