bad or no signal

All of a sudden I have no signal on my prosat v 8.it said bad or no signal, what could be the problem.

Try posting which satellites you're trying to pickup, dish and lnb type, any switches you're using and your setting in antenna setup; and someone may be able to help you.

You didn't have a thunder storm around you did you?

make sure you switch is not emp the box does like them

don't forget to check all connections including switches, if you got the signal level, but no signal quality the connection and switch are fine, you may needs adjust the dish, if you don't get the signal level, and no signal quality that mean connection or switches are bad
