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. Everything else between the receiver and the dish seem to be fine. At least my Acutrak III says there is plenty of signal. But when I try to get the signal strength for the 101 dish on the receiver I get zero. I am making the assumption that I should see a 13v switching signal on the coax when trying to get the 101 signal strength but I see zero voltage between the center and the shield. So either my assumption is incorrect or the 13v is not being applied to the coax. The rest of the receiver 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 some type of "one shot" protection circuitry, how can I fix it. Thanks, Arvid p.s. System configuration - Yesterday the weather in Minnesota was good enough that I could start my conversion to HD. I replaced the 3lnb dish with the 5lnb dish and performed alignment per the instructions and the Acutrak III. New cables between the dish and new ground blocks. New cables between the ground blocks and a new SWM8. Checked all four cables at the SWM8 end with the Acutrak III and everything looked good so I attached them to the four SWM8 connectors. Checked to voltage on the new cable from the SWM8 power module and it shows 18v, +/- a tenth. Attached it to the appropriate SWM8 connector - red to red. I also put a 75 ohm terminator on the unused SWM8 power module - the white one. The green light is on inside the SWM8 power module so that and the voltage on the coax to the SWM8 suggests all is good in those areas. Took the two existing legacy cables and attached them to legacy port 1 and 2 on the SWM8. I then went to the HDVR2 receiver expecting all to be well but got "no signal" message. Then started the debugging process above.
