There is a coaxial cable connecting each Set-Top Box to a wall outlet. Check each end of the cable to make sure:
- The connection is snug and secure
- There is no obvious damage to the cable
If there is damage to the cable, replace it with another coaxial cable.
If you are using a cable splitter, make sure its connections are secure.
