That is clearly NOT covered, nor is anything caused by a customer modification (customer messed with the dish, moved a receiver to another room, got a new TV and can't hook up the receiver to it right, etc.). The PP expressly does not cover customer-caused issues.
I think it is very hit or miss. When I had my house resided, my dish, which is mounted on the side of the house, was taken down by the contractor and re installed that day. Despite being very careful to mark things and making sure the mount was plumb, etc, the readings on other than the 101 sat were very low. At the time I did not have the PP. When I called D* to ask for someone to come out the CSR gave me two choices: 1) they would send someone "when they had the time" and I would have to pay $75 for the service call, or 2) I could sign up for the PP and they would have someone there the next day and not charge me. I chose option #2, and someone was here at 8 am the next morning.
Now maybe he was trying to make me buy the PP and maybe that gives a CSR some bennies, but he certainly made it sound like any time in needed my dish re aligned for WHATEVER reason, they would have some there to fix it at no charge.
