Video Asylum

I have found the performance and the flexibility of the b&k reference 30 to be remarkable in all ways digital. All my current sources such as CD, satellite, or DVD are digital (toslink or coaxial). I do have an odd problem which is causing me to seek service. Any idea?
This is the story. When the digital signal is interrupted such as between cd's or between satellite channels such as a menu guide or even any would be source not hooked up, the pre-amp says the signal is analog and outputs a loud high pitched tone around 2960 Hz, perhaps 5920 Hz. Occasionally, I get a hiss like white noise instead. The tone occurs even when the only hook-ups are a pair of headphones and AC power through a sophisticated filtered and balanced power source (cinepro powerpro 20). The tone is present for sources (all are phantom in this test scenario) except I get some white noise plus weak sounding radio station with am and fm. It occurs after the reference 30 has been disconnected from power for hours and returned through a proper boot-up sequence. I even turned off the power to all of the house save one plug to power the preamp but the noise was still there in the preamp. I also soldered some RCA plugs to short and stuck them on the analog input but it did not help. None of my other equipment have this problem but none of them are processing digital to analog signal.
