How to Set Up Your Comcast Cable Box
When you order Comcast Cable TV, it is possible to have your cable TV set up for your by a Comcast technician. However, this requires you to schedule a time have the technician come out, and you may be charged more money. You can instead setup the Comcast cable box yourself. Setting up the cable box requires connecting a single wire from the wall to the box, then connecting the box to the TV.
Things You'll Need
- 2 coaxial cables
- HDMI cable
- DVI cable
- Component cables
- S-Video cable
- RCA video cable
- RCA audio cables
Connect the coaxial cable from the wall jack to the coaxial jack on the left side of the back of the cable box labeled "Cable IN."
Connect the video cables from the back of the cable box to an available input on the back of the TV. You can either use HDMI, DVI, component video, S-Video, RCA, or coaxial cables (in order of descending quality) to connect the cable box. Connect the cable of your choice into the appropriately labeled output jack on the back of the cable box. For component video, you need to connect all three of the red, blue and green cables. Connect the other end for the cable you used to the an available input on the back of the TV. Some televisions may not have all or most of these connectors.
Connect red and white RCA audio cables from the "Audio Out" ports on the back of the cable box to the input on the back of the TV that you used for the video cable. For instance, if you plugged the video cable into the set of connectors on the back of the TV labeled "Video 1," you should also plug the audio cables into that set of connectors. If you used an HDMI cable for Step 2, you can skip this step.
Call 1-888-COMCAST to activate your cable box. The activation process may take a while.
Turn on the TV and cable box after activating, and set the TV's input to the input used to connect the cable box.
