The satellite name is whatever is programmed into the receiver. It doesn't pull this information during a scan or get it from space.
The receiver can say "Galaxy 19" and if it's aimed at Galaxy 19 you'll get all the programs. Equally, you can aim it at a different satellite and scan in different programs, or you can aim it at the ground and get nothing. The receiver will still display "Galaxy 19" in all these examples. You can even rename the satellite in your receiver to Neilsat. If the dish is pointed at Galaxy 19, it will still scan in the programs and report they are on Neilsat. So ignore the satellite name.
Probably your dish isn't pointed at anything or you have a setting wrong somewhere. In the latter case, most likely the LNB setting does not match the LNB in use. Check that it is set up for a universal LNB. Also double check the cable run from the dish and make sure the connectors are tight and not corroded. During testing, remove any splitters or switches that might be in the signal path.
Assuming you still don't have a signal, the dish is probably not pointed correctly.
As suggested, the best way to aim this yourself is to go into the manual setting and define a known, strong transponder. Then you can adjust the dish by watching the S (Signal) and Q (Quality) meter on screen. Like the satellite name, the S reading is not what it seems. It's saying there is a signal from LNB, not that it has a signal from a satellite. Your S reading will probably be around 70-90% and just sit there all day long no matter where the dish is pointed.
What you're looking at is the Q reading, which is the quality of the signal coming down. Assuming the dish is mispointed, you need to slowly move it around until you see the Q meter start to move, then even more finely move it until you peak the reading. Then you should be pointing at the satellite and you can blind scan. The dish needs to be aligned to within one degree of where the satellite is, so it might take a while and you need patience. But the folks here will help you through it.
