Well, the tech came out, which is the retailer who sold it to me, I thought that was strange. Anyways, he switched out the lnb and it worked perfectly. On the way out, the tech tells me that if it does it again, that he will RA the 811 because some of them will send to much voltage to the lnb and slowly fries them, and since this is my 3rd lnb, he thinks that is what might be going on. Anyway, its a day after the repair and guess what?? The problem is back so the 811 will be going bye bye for a new one. Hopefully that will fix it forever. Also, could this be a grounding issue?? As it is now, it is grounded only on the grounding block where the cable from the dish connects to come inside.
