My Tivo Series 2 (TCD140060) was working fine when I unplugged it to change its networking from wireless b (Belkin adapter) to a wired adapter. When I plugged the tivo back in, instead of showing any of the normal Powering up screens or Almost there..., it shows no video. Weirdly, the audio from my cable box is being passed through immediately, so I can hear the live audio from the cable box (no Tivo sounds and I can't change channels using the remote). When I plug in the box, the two LEDs on the front panel turn orange immediately, and stay orange. They do not change at all. I have tried unplugging the box several times, for a few seconds, then 20 minutes, still nothing. FYI, I got the Tivo latest update fine, and that did not seem to be a problem... I read here http://www.tivoblog.com/archives/2006/10/12/whats-wrong-with-my-moms-tivo/ that this could be a side effect of a bad power supply? Usually when a drive crashes, I see the Powering up screen... but this time there is nothing. No startup screen, no video, nothing.... Any suggestions?
