Motorola DCT6412 (Dual-Tuner) Set Top Box...
My old STB from Comcast died a couple of weeks ago so I upgraded to the DCT6412 (Dual-Tuner) DVR STB and I can't help but notice just how loud the thing is. It's a 'humming type' noise coming right from the unit whether it's powered on or off, I had to unplug it a day or so ago whenever I was listening to some reduced level music.
Does this sound like a grounding issue? It's the only component out of my system that makes this sort of noise and the old STB was completely quiet.
