You need to check if the problem is with your receiver, dish, LNB, or cable.
One easy way. to check your receiver, is to try it on somebody elses dish and see if the receiver works normally.
If it does then check that your dish is still aligned, and fixed correctly, although your description, of the problem, tends to make me think the problem is either your receiver, or LNB.
If the receiver works correctly, on another dish/LNB, then i'd check the cable, for any signs of water ingress, or damage, check the connections are tight, and correctly made, then finally try replacing the LNB, even if you borrow one, to use as a test.
