How to identify a broken cable jack
1. Locate your wall jack for cable
Once you locate your cable TV jack, do a visual inspection. To the best of your knowledge does it look okay?
Every room will have at least one wall jack, you may need to look behind furniture.
Does your jack have the right connections?
The previous resident may have removed the Cable Barrel Connector to install a cable splitter if you are missing a cable barrel connector. If your jack is missing a cable barrel connector, please contact TechHelp.
2. Test the connection
Is the cover missing? Many times the jack is fine even if the cover has fallen off.
If you feel comfortable doing so, test the connection to determine if the issue is cosmetic such as a missing or damaged cover.
