Ground Loop / Hum

[ihmeyers]

I've been trying for the past month to stop the hum when using my RF Modulator with the Admiral. It's definitely video not audio induced as it appears even when no audio cables are connected. I'm using a high-end Monster S video cable from the DVD player to the modulator and a decent coax from the modulator to the set. I am almost at the point where I want to scrap the modulator and try something different. On some programs the level of hum is pretty intrusive. It's not present on any off the air channels so I'm pretty sure it's not a tube or something on the board. Any ideas?

Thanks!
