Definately reset the TV also (by unplugging it). In my case (MITS DLP) it works best by plugging the TV back in first, then the Tivo. I think Tivo does a better job of offering its hand than receiving the heandshake.

Have you tried rebooting both TiVo as well as your TV's (unplug everything, wait 10-15 seconds and plug them back in)? HDMI requires a handshake that may have been broken.

It doesn't seem likely that a lightning strike would destroy only the HDMI capabilities of any CE equipment...but hey, you never know!

I have reset the HDMI handshake this way several times. I have found that when I plug the TV back into power first, and let it sit 30 seconds, then plug the Tivo in it works better than doing the Tivo first.
