I have a DirecTV HD DVR. It's the first one after the Direc TiVosHD went away, it's 3 years old. Last night it start where it keeps restarting or something saying "your directv receiver is starting up," and then it blacks out again and never actually starts up. Just this loop never gets pass this one step, and it usually doesn't even output that message to the TV. Any quick fix to play with or try? I tried unplugging it 30 minutes. Any stores that have these on shelves so I can quickly swap them out by buying a new one? Does Costco still have them? Thanks.
