Hello, I am receiving the error message "The DVR has detected a serious problem..." on a green page shown on my TV. This appears whenever I try to start my TiVo box. I have read in the forum I will need a new box, but I am unsure how to go about sorting/collecting this. Can anyone provide relevant advice please. I have kept the box turned on, turned it off, and it keeps going through the same routine of going blank to 'Starting up' and then automatically to this message, and then repeat...repeat...repeat.
