We had a couple of power outages the other day, and although I have this particular TiVo HD on a surge suppressor, when the power came back, the machine won't stay up for more than a few minutes before rebooting. I'm trying to get it to kickstart, but no matter how I time the button presses, it simply won't kickstart. I've also tried removing the DVR Expander with the same result. Is there any way to get past this issue? I'd at least like to see if I can give the drives a scan before I give up on it.
