My TiVo is showing a green screen saying a fault has been detected and needs 3 hours to fix. It's been like that for days.
It seems I need a new box.
That usually happens when the TiVo software detects damaged areas on its disk and tries to repair it to continue.
Worth trying a power off and on to see if it recovers and, if not, you’ll have to call in to get it replaced.
I restarted. Went back to the same green screen for hours.
