Add me to the club, my TiVo got the grey screen of death as well.

I tried all the 6 hour turn off type stuff to no avail.

So I bit the dust and rang TiVo support.

They did nothing but take my name and promise to call me back..... They never did.

I called them again and asked why they didn't call me and the guy didn't know and didn't know how to find out......

I went through the standard turn off for 6 hours and disconnect the aerial stuff which I told them I had already done. I asked why they wern't doing something about what was obviously a common well known fault.... he just denied it (of course)

So I have to wait 2 days for the problem to be escalated and for someone to call me back.

However some good news. I left it turned off for about 12 hours, disconnected everything except the power and composite output, and it booted up.

It's been 24 hours, so far so good.
