Mine started working again! The (relatively) short version: My 5 month old HDtivo looked dead. No signal, no power lights, and only the sound of the hard drive spinning and fan to tell me it was even plugged in. I pulled the plug and rebooted it and after the "almost there a few more seconds please" screen, it would shut down completely. No lights on the front-- nothing. I did this 3 more times to make sure and every time the same thing happened. I called Directv and because I have the protection plan they said they'd send out a replacement within three days. Fine. So I go about my business and then later that night I plug it in and it does the exact same thing, only this time, on a lark, I press the Format button and Voila, the lights on the front come back and it continues to boot. It's been running normally now for two days. The only problem is I got my replacement machine THE NEXT DAY (who knew they'd be so fast) and now I have to send back my old one or they charge me $400. Which one would YOU send back?
