If There Is No Picture or No Sound on HD Channels

Verify that you subscribe to the channel you're trying to watch.
Check that the TV Box is on.
Confirm you're tuned to an HD channel.
Double-check all connections and make sure you're using HDMI or component cables.
See if you're able to view other HD channels.

I hope this is helpful? PLEASE "ACCEPT" and mark it "HELPFUL" to complement my little effort. Hope to bring you more detailed answers
