While updating our 2630 and 3000, I believe that the display and reciever lost power.  The display seems to have updated correctly but the reciever is not communicating to the display.  The reciever is flashing a red light and I read in the manual  that this means it does not have enough voltage but I know for a fact that it does.  Is there a factory reset that I can perform or do you have other suggestions? TIA
