We have a 4 year old Series 2 Toshiba RS-TX60 with lifetime service. We had a power outage a few days ago related to some thunderstorms. This afternoon, the TIVO box starting acting up. It's constantly trying to reboot - sometimes it gets to the Almost There screen, mostly it just cycles through the Powering Up screen, flashes black, hard drive clicks, and then it's back to Powering Up.

What has failed? The hard drive, the power supply, or the motherboard.... The search I did in the forums here has me thinking power supply - I'm so hoping it's not the motherboard....

Any help would be appreciated.
