We just got a new Edge - 2TB, upgraded to be a 3TB by weaKnees - and we hooked it up to our tv and everything connected and started up and was working fine and then it got to the cable card part of the set up and we realized we hadn't put that in. So we unplug the Tivo, put the cable card in, and replug everything in. Now the Edge won't start up. The cable card was from a previous TiVo, and when it wouldn't start up, we took the cable card back out to rule out that as the issue. The lights keep starting up on the front as if it's booting up, but the tv doesn't register it as putting out any signal. The input screen will flicker black as if it's retrieving the signal, but then it quickly goes back to no signal. I've unplugged and replugged everything multiple times. Does anyone have any ideas??
