I've had a Dreamcast for several years with a bunch of games.  Haven't played it for about a year, dusted it off, plugged it in and I can't advance the part where it asks you to put in the date.  Nothing happens, it just sits at that spot.  Thought it might be the controller.  Tried 5 different ones in each plug.  Nothing.  Tried different games.  Nothing.  Tried no games.  Nothing.
Went down and bought a used machine for $20.  Same problem.  Tried new controller from the used machine.  Nothing.
Tried different input plugs on the TV.  Nothing.  It is getting power, the power light is on, I can hear the disc spinning.
Only other thing I can think of is the signal cable to the TV but I'm getting the start up Dreamcast sequence so it is getting a signal.
I tore one of the machines apart to take a look at the connectors and everything looked fine with all the pieces in place.
Any suggestions?
