You need to be more methodical, just point the dish in the right direction.
Go to dishpointer, that will give you a rough direction, you want 28E.
You can use your receiver and TV as a meter.
Pick a transponder say 10773H on 28E (see lyngsat for details). Put the dish so it faces roughly the right way, set the elevation so that the dish is roughly vertical, then slowly swing the dish from one side to the other, hoping to get good signal quality.
If you get nothing, change the dish elevation a bit and try again.
Also make sure you have no obstructions above the required elevation angle, dishpointer will tell you this ( 20 to 25 degrees maybe, in NI)
