[TiVo Central] Help Tivo stuck on powering up

[bessiepat]

Hi,
I have a Tivo Series 2. When i got home from work today, the screen
said welcome, powering up. It was working fine this morning.
It's been on that for a couple of hours at least. How long is it
supposed to be on the powering up screen? I thought maybe the power 
haed been interrupted originally so
I tried turning off the power and its still on powering up.
Any ideas anyone? I really hate to have to call customer service.
thanks
Patti
