The other night I went to flick over to my Tivo and it had a black screen. Pulled the power plug and left it for a bit then plugged it back in.

Got the Tivo Welcome screen so thought everything was good and went and did something else for a bit. Flicked back over and the screen was black again.

Repeated the process and watched it this time, shortly after getting the Tivo welcome screen the screen flashes with a bunch of colours and then goes black.

When using the remote I can see the LED on the front of the Tivo unit flashing in response but nothing happens.

Tivo was modded about 2 years ago and is running a Western Digital Red drive.

Any troubleshooting steps to take?

Cheers

Matt
