Welcome to the Community!
Really 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 your input signal levels that will need to be adjusted. I'd also like to have your hard drive checked out.
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.
