It looks like one of my old HR 21-100s has finally died. It’s running the receiver self test and gets to the “almost there” screen then starts running the receiver self test over and over and over. DirecTV is sending a replacement and didn’t even give us a hard time about it. I’m not sure exactly how old it is but I believe we got it sometime in 2008. Now to see what model of DVR shows up in the mail.
