We had a bad storm here yesterday with several lightning strikes. After the storm I had a 771 error on one of my receivers. I have a Slimline connected to an HR20 in the house and an H20 in my shop. The H20 is fine but the HR20 is showing the error. I swapped the coax connections at the LNB with the same results (seems to rule out the LNB?). I brought the working H20 into the house to test and expecting it to work, but to my surprise I got the same error on the H20(I haven't tried the HR20 in the H20 location yet).
This was a head-scratcher and after some thought I couldn't help but wonder if the grounding block did its job and took the hit? (The H20 is on a separate block). My cables running from the dish to the house are relatively new and buried the entire length (40 ft). It was dark and raining and I had to give in for the night. The grounding issue did not occur to me until this morning so I have not been able to check for continuity or receiver voltage at the block. I am looking for some insight as to what may have been the cause and steps to a solution. I have always installed and serviced my own equipment but his is a new one to me.
