Comcast is a communications provider that supplies customers with television services, Internet and phone connections. The company's television services includes regular and digital cable, and both types require a cable box to connect to your television. You can ask for a Comcast technician to visit your home and set up your cable box, but you'll find that it's very easy to do this yourself. The entire process should take only a few minutes.
Connect the coaxial cable extending from the wall outlet to the "Cable in" port on the back of the cable box by twisting its plug connector clockwise using your fingers until it is firmly in place. This coaxial cable connects to the cable service. If it hasn't been set up yet, you'll need to contact your local Comcast provider.
Connect one end of the coaxial cable you purchased to the "TV/VCR" port on the back of the cable box. Connect the other end of the coaxial cable to the "Antenna in" port on the back of your television. Both ends connect in the same way as described in the above step. This process only works for televisions that are not HDTV. Go to Step Three if you have an HDTV.
Connect one end of your HDMI cable to the HDMI port on the cable box. Connect the other end of the HDMI cable to the HDMI port on your television. Both of these ports resemble the USB ports on your computer.
Attach one end of the power cord to the back of the cable box and plug the other end into the closest wall outlet.
Turn on your television. If you have a standard television, you will automatically be able to view all of the cable channels that were included in your Comcast cable package. If you have a HDTV, press the "Input" button on your television's remote control and select the "HDMI" option to view channels.
