Everything is now set up properly for my 942, thanks to other forum members ideas. But I'm not sure about the sound this receiver makes when it is not being used. When both TV1 and TV2 are off, and the 942 has no lights on but is still plugged in, it makes the same noise as when it is on. The unit stays slightly warm, and has a humming noise which sounds like a fan, plus clicking noise from the hard drive. While the noise is not loud, it seems strange to me it should make any noise at all when it is turned off. Is this normal?
