First, try to determine where the problem is. There are three common places that problems can occur: the handset, the cable, or the phone itself. If the handset is not working, remove the battery and replace it. If that does not work, try cleaning the contacts with a pencil eraser. If that does not work, you may need to purchase a new handset. If the cable is not working, unplug it from both ends and plug it back in. If that does not work, try replacing the cable. If the phone itself is not working, unplug it from both ends and plug it back in. If that does not work.

There are a few things you can do to repair a telephone problem. First, check the phone's wiring to make sure that everything is plugged in correctly. If there is no change, try cleaning the phone's connectors with a cotton swab and some rubbing alcohol. If that doesn't work, you may need to replace the phone's handset cord. Finally, if nothing seems to be working, try calling your service provider for support.
