Hi - I have received the following from TiVo support:

"Apologies for the difficulty you are experiencing. Please try the following steps (if you haven't done so already):

- Perform a hard reset, this is when the TiVo is unplugged from the power for at least 6 hours.


- Plug the TiVo Back in with only the power and the av connection to the TV (ie no wireless or ethernet, antenna or expander drive), if possible directly to a wall socket (or a different wall socket) and using the yellow composite video cable.


- Leave the TiVo on for at least 1 hour to see if the TiVo will reach the TiVo Central menus.


We hope this response has been of assistance and as a valued customer we appreciate your feedback.

For any future enquiries related to this issue please reply to this message leaving the reference number in the subject.

Regards,

TiVo Support"


I will try this overnight and post here as to how it goes...
