Has anybody come across the tivo box cutting off signal to the TV every 5 to 10 minuites lasting upto 10 seconds everytime. I've changed hdmi and swapped inputs at the back of tv, swapped TV, reset the box. Gone into settings and made sure 1080 was the only signal.. Nothing works. I even left it all disconnected and switched of at the plug over night to see if it worked, but nothing works and it still does it.
