I hope I have posted in the correct forum category. I have a problem with the receiver LNB power. Over the last two days I have done the following:
1. checked output voltage (18V) at receiver connection. OK.
2. " voltage at grounding block - OK
3. Installed new cable connectors on original cable. Continuity check + voltage is OK to dish.
4. replaced original cable with new RG6 with manufacturer's connectors.
5. As power was reaching the dish, I decided to check alignment (aimed at 91W Nimiq1). I have a separate dish on 82 on another receiver and it is working fine. When I connected the satellite finder to the 91 dish, the meter power shut off immediately when the receiver cable was connected. I disconnected the cable to the dish and the power came back on. As I thought I had a faulty LNB, I swapped it with the one used on the second dish and the same thing has happened. All told, I have connected four LNBs (two were obtained from a neighbour who took a b.. dish down.) All reacted the same way. I have full power to the dish until the LNB is connected and then no power.
What else can I possibly check???? Any advise would be sincerely appreciated.
