Okay, so my AM21 off-air channels went out shortly after a couple stations from my receiver (in which the dish needed realigning) went out. Someone came and aligned the dish, but the off-air stations are still a bust. Does the dish still need more aligning for the off-air stations to work. Or did I bump something from looking at my Genie? Is there anything I can do to fix it? Or has it gone defective? I did check the connection from the Genie to the AM21 and it's on tight.
