I have two series 3 tivos bought two years ago at the same time. One is fine and the other suddenly is not. The power light is flashing green, but no other lights. I have read the other threads that start like mine, but unplugging the Tivo, waiting a bit and plugging it back in solved their problems, but it isn't solving mine. Nor is any Tivo screen showing on the TV. The TV itself shows the same "no cable input" whether the Tivo is plugged in or not. I have checked the input and it is the right one. We haven't touched the Tivo since we initially set it up because it always works great! So what's up? My router doesn't see the Tivo. My TV doesn't see the Tivo. Yet I can go online and log into My Tivo and see what's on my Tivo's harddrive. Tivo desktop cannot see it. Any ideas? Thanks!
