Hi moooey74,
Welcome to the Community!
Sorry to hear you're having trouble with your TiVo®.
I've run a diagnostic on your equipment and I can see an issue with the signal that's likely to cause this type of fault. I've sent you a private message (purple envelope at the top right of your screen) so I can arrange for a technician to take a look at it.
Look forward to hearing from you! 
Josh
