Our Tivo HD has been sporatically restarting quite a bit lately - about once a day, but sometimes only twice a week or so. It's super annoying, because it always seems to happen right when we need to use it of course. And it takes quite a bit of time to restart, around ~10-15mins?

Anyway, I wanted to run through some of the kickstart codes to check the hard drive. But no matter what I've tried, I just can't initiate it. I unplug it, walked away and came back 5mins later. With remote in hand, I plug it in. All lights flash VERY briefly, then right away the green light flashes once. A couple seconds later, the "Starting up..." screen appears. I tried pressing and holding pause at various times here but no luck. I also tried just holding down pause as I plug it in, but nothing happens.

I've tried staring at the green light to see if it flashes later on, but since it takes up to 15mins to finish rebooting I might be missing it when I dare to blink :P. Can anyone give any tips on how to catch this thing? How soon after plugging in the power should I expect the green light to flash?

For grins I cracked it open to inspect the capacitors, as I read they can corrode and cause restarts. It looks brand new inside, nothing out of place. I blew out any dust for good measure before closing it back up.

Thanks!
