In other words, once you have set the TV remote to the correct input for the cable box, make sure the cable box is turned on using the cable box remote. If nothing comes up still, go through the different inputs on your TV. It’s possible where it is plugged in got changed.
I’ve got a Vizio TV, and I thought the HDMI inputs were no good—until I figured out they’re numbered from bottom to top!!!
