Hi all, first time poster and unfortunately first time TIVO not working. I hadn't watched the Tivo for a couple of days. I sat down to watch and got the Powering Up loop. I unplugged the system figuring that it needed a reboot. Upon powering up, I got noting at all. So I took the unit apart. It's a TCD24004A purchased in Jan. 04 from WK with a 120 Gig drive upgrade. The first thing that struck me when taking the top off was the internal fan that was cooling off the mother board was definitely shot. Next I noticed that when I plugged in the unit, the fan in the back (powered off of the motherboard) was spinning, but nothing else was going on. Neither HD's were even going into standby. So I unplugged the IDE cable from the motherboard and one drive immediately started spinning-up. No data access, but the platters were spinning. Plug the IDE back into the motherboard, and the drive stopped spinning. The other drive isn't doing anything. The other thing I did was power up the unit, having everything plugged in, and pulled the power to the motherboard. When I did that the fan in the back stopped, and the one 120GB drive spun up. I occasionally get a flashing red and green light on the front of the unit. I suspect after all of this trial and error that I have a blown drive and motherboard (and of course CPU cooling fan). I was wondering if anyone has encountered these sort of symptoms and what they might mean. I know testing the HD's externally is a good thing, but we're a MAC house. Thanks in advance!
