On the back of the TV, there is a video input port for the coaxial cable/RF cable. Please connect the Cable/Satellite box to the TV by using the coaxial cable/RF cable.
Then, press the Home button on the TV remote, and select Input-->TV Source.
If your cable/satellite box uses the HDMI cable, please connect the box with the TV via the HDMI cable, and then select HDMI as the input source.
If the box does not work with the TV properly, please feel free to call the TCL hotline for further help.
