My tivo just yesterday stopped getting live tv, there is no sound and just a black screen. I can press the info button and it will show what is supposed to be on the channel, but it is all black. I am using a coax cable going from the tivo to the tv, and I have tried connecting my cable line straight to the tv and the cable comes in fine. I have restarted my tivo and gone through guided setup again. In guided setup however, when its asking what station is on a certain channel, its always black in the background. Can someone help?
