CBAND LNB TEST??

[elam budmore]

Does anyone know of a way to test a LNB i have been having problems seting up an old dish and im starting to wonder if there may be a problem with the lnb. im seaching for sat G1 ..chan. 5 and 3 i had it last night for a bit, now i cant seem to find it

is there any reason i would have a harder time finding these satalites today rather than last night, i just spenr 3 hour looking for G1 .. i had the dish and such marked last night and toda all i can get at that possion is just a bit if what looks like it WANTS to go into a picture but it doesnt quite come in. im looking to pull in a open analog channel

[FONT=Arial, Helvetica]when you lose every picture on every satellite it is the LNB. Test the voltage coming out of the receiver. The receiver sends 18-21 VDC out to the LNB to power it up. If you have this voltage present on the coax cable at the dish, the receiver and cable are fine and the LNB is bad.[/FONT]
