Gary got a TIVO Bolt six months ago that uses a cable card, but it's now stuck in "guided setup" with his zip being wrong. How can he reset it? Leo suspects that particular Bolt is defective, perhaps with a faulty hard drive. But Leo replaced his, and it's wasn't the hard drive. So the next option is the power supply. But it sounds like the Bolt isn't all that reliable.
But Mike B in the chatroom says that your cable card may not be correctly configured. Go to your cable store and either ask for a new one or repair that card to your account.
