Advertisements On boot up, Green light is on throughout this process. It shows the Welcome screen (amber light flickers a bit after a moment but never does again) -> briefly black -> Welcome (this repeats three times) -> Almost there -> black -> no signal -> black (this repeats many times). Then nothing. I tried replacing the HD, but there was no change. I put the original drive back in. Same problem as expected. I unplugged/plugged it in to run through the cycle many times, trying to understand what was going on. After many times, it miraculously booted up and showed me several random five year old recordings (including the Bionic Woman and He-Man in Spanish!). I played around with the UI and played back some of the recordings. Everything worked great. I decided to take the opportunity to do my factory reset (smart or dumb?) thinking between finally booting up and then a factory reset, the OS would have returned to proper operation. The reset appeared to go well, although not having ever reset a Tivo, I'm not sure if all the reboots and time it took were normal. It did boot into the setup process, asking for zip code and Wifi password. Then it wanted to download guide info. This seemed to hang on "Loading Info" and the Tivo abuptly rebooted. This happened several times. I went to bed. Today I find it will not get past the "Almost there" screen, but the screen looks different than it did before I attempted the reset. The colorful Tivo logo has been replaced with a white silhouette logo. I have attached photos of both to show the difference. I am using the power supply that came with the Tivo, but I did also try a laptop power supply previously and got the same results.
