How to Make a Cable Box Work With Comcast Cable
- 1). Connect the coaxial cable running from the wall outlet into the "In" port on the back of the Comcast cable box.
- 2). Plug in the RCA cables into the "Video Out" ports on the cable receiver box. Insert the other end of the cables into the "Video In" port on your television.
- 3). Power on the television and the cable receiver box. Press the "Input" button on your television remote and select "Video." You can now watch your Comcast cable through the connect cable box.
