Genie Mini flashing yellow - DirecTV

I have a genie mini C51-500 that recently started flashing yellow and unable to connect. Have unplugged and plugged back in, pushed reset button, reset main box, and refreshed on-line. Nothing works. Also held Directv on/off button for 15 seconds, didn't help. Now the remote won't even work.

This question, "Genie Mini flashing yellow," is about DirecTV channels, programming, equipment, and sports.
