Okay, here's how I get mine to work if it won't search. Unplug receiver, turn on the dish (so that it can orient itself) wait about a minute, now plug back in the receiver (you must have 110V power for the receiver to work) The receiver should turn on and start searching. Once I find the bird I turn the dish switch off. Turn it back on if I want a channel on another bird.
Good Luck, it's not that hard, but patience is a virtue.
