make sure your receiver's settings are for a standard LNB, it's frequecy shown should be 10750
make sure LNB power is set to "on"
Make sure there are no switches, meters, or anything else in line when you are looking for signal. Coax directly from lnb to reciever to begin with.
make sure the coax cable from lnb is plugged into "LNB" or IF IN on back of reciever (not antenna in)
once you set your receiver to
IA5, you must also make sure you are set to an active transponder (think of it as a channel slot)
use this:
12177 V 23000 or 12152 H 20000
