We inserted the cable card in the slot in our TV, but all our TV will do is post a message: "Cable card inserted. Cable service must be connected. Now receiving channel information." It has been doing that for over a half hour. What do we need to do to get the card installed and the cable running?
Call the cable company and tell them you have just installed a cable card, and upgrade your programing to receive digital channles if you weren't already.
Whether you were already getting digital cable or not, they will then have to authorize your card from their system.
You will likely need the make and model number of the TV, a serial number off of the TV, as well as a number off of the card.
