What should I check if I have no video, a snowy picture or I cannot tune to any of the digital channels?

Make sure all cable connections are secure and that the TV is tuned to the correct input (Channel 3 or HDMI or component).  Also make sure you are actually controlling the cable terminal (press the CBL button on the remote control).
