Advertisements I'm seeing the rebooting problem on my TiVo HD. No remote issues as far as I can tell, it continues to respond to the remote up until a few seconds before it reboots (and in many cases I'm not using the remote at all when the TiVo reboots.) Usual symptom: I'm watching something the TiVo recorded, and it suddenly goes to the "Powering up" screen. Sometimes it gets caught in a loop where it's constantly rebooting, with anywhere from 15 seconds to ~2 minutes between completion of one reboot and the next reboot. Unplugging it for several seconds seems to stop that. ("Seems to" because it could be coincidence, and because I'm usually so fed up at that point that I switch to watching something on DVD or AppleTV.) At first I thought it was the Tuning Adapter, but I took it completely out of the loop (unplugged the USB cable, and routed the RF cable straight from the wall to the TiVo), and it continued to do it. Then I figured it was the power, so I moved the TiVo onto the (tiny) USB my cable modem and router are plugged into. The problem continued. The one thing I haven't checked is switching from HDMI to Component, I'll try that tonight. (And I'll be pretty ticked off if it works, because that'll leave nowhere to plug in my Wii. Yay for one multi-purpose Component/AV input on the TV. Not.) I have no idea when the problem started, prior to a week ago there was a period of about 3 months where I barely watched any TV. But the last time the TiVo missed recording anything was back when it last had the "hangs on reboot" issue sometime in January, and since I've started watching TV and noticed the issue I have missed a few recordings. Possibly not coincidentally, I started watching TV again when I got a new TV -- and switched the TiVo to an HDMI input.
