NO SYNC SIGNAL. - DirecTV

#1
My TV says NO SYNC SIGNAL. I've pushed the red button on the genie. It then says "This will take a minute". Then, "Running receiver Self Check. Then says, No SYNC SIGNAL, and the genie goes off.
Also, on the TV it says HDM1:2, (I think it should be HDM1) and the Input is 2 (I think it should be 1). I don't know how to change these. This is on my TV in our basement.


This question, "NO SYNC SIGNAL.," is about DirecTV channels, programming, equipment, and sports.
