For the past 10 days to 2 weeks my DSR-530 has been locking up and recycling. When I turn the unit on, it locks up within a few minutes and goes through a power recycle. Then it will constantly recycle, over and over again. When I do eventually get it come back, after a few minutes it does it all over again. I received a message in my unit last week about possibly having to do a power recyle to get the NFL Sunday Ticket to work. Does anyone think a problem exists in the maps that may be leading to this? My unit has run flawlessly for the 2 years and 4 months that I have owned it, up until this issue has arisen.
