Last night was the worst lightning storm that I've ever seen. So bad that I would have ordinarily unplugged my Tivo S3 even though I'm using a surge protector. Unfortunately, I also have a cold and wasn't thinking clearly because of the NyQuil. So... I wake up this morning and there is no audio or video coming from my Tivo. I unplugged the unit, waited 15 seconds, and plugged it back in. All the lights on the Tivo look normal (it's even recording a program now), but I get absolutely no audio or video. I had several other things on the same surge protector that appear to be unaffected (e.g., my plasma, XBox, and DVD player). My throught is maybe the surge came through the Coax, which I had neglected to run through the surge protector (my cable line is buried, so I didn't think of it as a big risk). We never completely lost power last night, though it did flicker enough for my bathroom radio to lose it's preset station information (but not enough for my alarm clock to lose the time). Any thoughts on troubleshooting this thing. I really don't think it's the power supply since the unit seems to be working normally except for not sending any audio or video signal to the TV.
