I switched my Series 2 TiVo to another TV. I go through the cable box, but those hookups weren't changed. Since then TiVo and the TiVo remote won't work. I see the lights working, but the tv doesn't display anything, therefore I can't get in to setup to reconfigure the remote. I am watching cable channels and have to manually change channels, but nothing regarding TiVo is visible through the TV. Am I supposed to restart TiVo after switching to a new TV? Any suggestions are appreciated.
