I am not sure I understand?
I already wrote that the hum is entirely unaffected whether or not the cable that comes from the outside, from VirginMedia, is connected to the STB or not.
This cable is the only F-connector that I can see anywhere, so I am not sure what you are referring to. Could you please explain in more detail?
Also, as I had written before, the hum is produced by the STB already if it is only connected to a power supply and any single audio/video cable running from the STB to the receiver, connected anywhere, regardless of the state of either device (i.e. both in standby, except for the subwoofer itself.)
(Also, the STB is fairly hot at 48⁰C. I was told by VM phone support that this is normal for the ScientificAtlanta 4200DVB. However, the part of the NagraVision SmartCard that is inside the STB has turned to well-done brown color. There is nothing on top of it, it has about 5cm room to the next shelf above and to either side, and room temperature is at at 20⁰C. The STB is constantly burning 30W, regardless of standby.)
