We are canceling our cable. So we had to pull the cablecard from the tivo (tivo premier w/ DVR expander drive) to return it. I thought we'd be able to use the tivo after that to watch the recorded shows and see what season passes we had. But now I'm getting a black screen (not just on "live tv", the UI is gone too, nothing but black no matter what I do). The only thing I can make it do is make the error sound when I press the tivo button on the remote. After restarting I can go through the guided setup but at the end I always end up back with a blank screen. Has anyone else come up against this problem after yanking a cable card? Is this some kind of copy right feature or am I just doing something wrong?
