My 722 that I have had for over 5 years is starting to fail. I keep getting the Complete signal loss 015a signal code 11-12-11 error. I just had a service call today where they verified my dish was peaked and the signal at the end of the cable in the house is good, but the receiver keeps having this issue. I am thinking of upgrading to two hoppers to replace my 722/622 setup as I don't want to go below 4 tuners in my house. My main question is what to do with my purchased receivers if I decided to upgrade the 722 and 622 (checked on my account and they still show as purchased I know some have had trouble with it changing on them) The 722 is dyeing and the 622 is old so should I just salvage the HDs from them not sure I would want to go thru the hassle of selling it, but worried I will just hold on to them forever like the 510 and 3000 model receivers I still have from dish.
