With nothing connected to the receiver, uncheck super dish and alternate and run a check switch. It should come back with no switch detected and no satellites listed in the results. Now power off the receiver (unplug if necessary) and connect the receiver to the tailgater directly (new cable would be a good idea) and power on the receiver and your TV. If you do not get the Tailgater setup screen the 2 pieces of hardware are not communicating and you will then need to try a new cable before contacting King Dome to see if there are any additional trouble-shooting options.
