My 622 died also three of them!

Couple of things

I just got my replacement 622 (my previous unit would freeze and then restart at will) and for the first day it worked fine...well now its restarting all the time, I think this one restarts more than the last one...not sure what I should do, any suggestions...

Is the dish grounded and the 622 also grounded. If so there is a possibility that the two grounds have a different potential. This can cause a conflict that could be the whole problem. The other thing is are there and barrel connectors in line for the sat signal? If there is corrosion on any of the F connectors this will cause a problem from the LNB's to unit.
