Just picked up and installed a new tivo which I am setting up for a family member. But as soon as I switch it on it has a green flashing light, and nothing appears on the screen. I do have 2 tivos myself, and they never had this problem. Anyone know what a green flashing light means?

I have rung telecom broadband/tivo support, and they don't know either, but have said to turn off for 6 hour s to hard reset and try again,and if it is still occurring return to the store. This will be the second one I will have to return after problems shortly after buying, so there DOA rate must be quite high.
