Switched to new TV

[StacyAEH]

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.

If your TV has multiple inputs, then try cycling though the different inputs on your TV. Maybe your TV tuner is using the wrong set of inputs.
