Question about Insignia 42" LCD Flat-Panel HDTV
If it is a cable box and you are connecting via coaxial cable using the rf converter in the box it is usually channel 3-4 but it can often be switched. If it is a satellite box it may use a high channel number like 73. Keep in mind that there is a traditional tuner and a digital tuner in your tv set so you made need to connect the cable and then do a channel setup for it to sense the active channel.
The image quality is best when the cable box is connected in this order from poorest to best; coaxial cable, rca cables (red,white,yellow), s-video (on older televisions), component video and optical audio using the three yellow, blue, green cables for video and a white or red for audio or optical input, DVI, or the best, HDMI with support for 1080p and audio. On your TV you should use an HDMI cable and simply change the Input or source button to that. The HDMI cable integrates video and sound and it will transmit a dolby surround signal to your TV just as a separate optical connection will.
