The simplest way to check the wiring is to disconnect the F56 at the LNB end and check the voltage -- it should be around 13 or 18 volts; this will tell you three things; first, that the receiver is putting out the necessary voltage to power the LNB; second, that there are no shorts or opens in the wiring or connectors; third, that the HH motor is passing the voltage through to the LNB. Then try measuring voltage at the F56 connector that screws onto the HH motor.
I find after time that corrosion builds up on the F56 connectors outside at the LNB and eventually this will cause a malfunction -- when you take it off the LNB to test the voltage take a good look inside the F56 connector -- if it shows any signs or rust or corrosion build up, replace it. As a sidenote, if you are using those crappy thread-on connectors that came with the motor; replace them with proper crimp-on connectors. Those thread-on F56/F59 connectors are garbage.
If after testing the voltage and connections you still have no signal, you should do a factory reset on the receiver; then reprogram the parameters you need (like DiSEqC 1.2, correct satellite, etc) and rescan the channels. If you still have no signal then change out the LNB. If you still have no signal then I would suspect that the dish has moved.
Good Luck
