I received the following error message "Your receiver is unable to receive a signal". What should I do?

 Updated 

Because weather can affect the signal to your TV, the following message usually appears during poor weather. After the weather clears, the problem should be resolved.

If not, please double-check that the signal cable (LNB) is properly connected.

If the problem persists, please contact your local customer service center and they will walk you through the necessary steps.
