I have a HDVR2. In the process of hooking up new cables between the dish and the receiver the cable may have been shorted – center to shield. Now the receiver claims is can not find any satellites.

When I try to get the signal strength for the 101 dish I get zero. I am making the assumption that I should see a 13v switching signal on the coax but I see nothing. So either my assumption is incorrect or the 13v is not being applied to the coax. The rest of the system works fine so it is not a total power supply failure. I am wondering if there is a fuseable link in the tuner output that might have been “activated” to protect the output circuit if the cable is shorted. And if there is a fusable link or some other such protective circuitry, how can I fix it.

Thanks,
Arvid
