I have 2 622 receivers but the main one on the Family room was installed in 2004 so is almost 5 years old. I am starting to see intermittent 1 second dropouts of audio on both live TV and on some recorded shows. Happens sporadic- maybe 1-2 times a night and I haven't seen a trend towards certain channels. Could this be a sign that the 622 is starting to reach the end of it's life and should I start asking DISH for a new receiver or just wait and see if it worsens? It is a leased receiver so what would DISH offer me if replaced at some time?
