Cable TV Has No Sound on Certain Stations

by Eoghan McCloskey

If you use any cable TV service at home, it is inevitable that you will encounter some technical problems with that service at one point or another. You can always turn to your cable provider's technical support service, but often enough, exercising some basic troubleshooting on your own can resolve the problem and save you valuable time. Missing audio on certain channels, for instance, is a common problem that you can resolve in a few simple steps.

Troubleshoot the TV

It is very often the case that for simple cable TV problems, the TV itself is the source of the problem rather than the cable service. Make sure your TV's SAP function is disabled because having this option activated will cause missing sound on certain channels. Test the TV's other A/V component devices such as DVD players and video game systems to see if audio intermittently cuts out on those devices as well.

Troubleshoot the Cable

If troubleshooting your TV does not resolve the issue, it is time to troubleshoot your cable service. Locate the coaxial cable that attaches your wall cable outlet to the coaxial input on either your TV or a digital cable box. Tap or jiggle the cable and check if audio is restored to all channels. Make sure the coaxial connectors on either end of the cable are hand-tight. If audio is still missing, remove the cable and inspect the copper needle running through the middle to see if it is bent, broken or damaged. If it is, replace the cable.

Isolate the Problem

If you eliminate an individual coaxial cable or TV as the problem, it is necessary to determine the scope of the audio problem. Note which channels are missing audio and check the other TVs in your home connected to the same cable service. See if the same channels, different channels or no channels are missing audio and repeat the test for every TV in your home.

Contacting Your Provider

If none of the other options fix the problem, contact your provider and report the problem to its technical support department. Inform them how many channels are experiencing the issue and if the issue was duplicated on the other TVs in your home. The representative will likely take you through some additional troubleshooting steps over the phone and dispatch a repair technician if necessary.
