The ghost of closed captioning!! If someone can figure this out I am very grateful!!?

What keeps happening is the closed captioning will be on for a few days and then mysteriously disappear. Then a week later it reappears. This cycle keeps happening. I have TIVO, Qwest cable, and a Philips TV. Each of them blame the other. So why is it going on and off? So that is why I am blaming the ghost. Do I need to buy a new tv? By the way I already read each instruction pamphlet several times with no ado. Maybe my ghost is deaf??
