Sometimes my television reception is good and sometimes it isn’t. Here is an example of a QAM unit that you can purchase. If your TV was manufactured prior to 2008 there is the possibility the TV may require a QAM converter. My television receives the QAM digital channels but I do not have audio on the digital channels. Turn the device off, unplug it from power, and bring it back up again.Check the connection on the cable from the wall jack to your set to ensure that it is secure.Most remote controls have a menu button that steps you through this process. Repeat the steps for cable channel recognition (or channel scanning). If your television has a remote control, the batteries in the remote may have died.Repeat the steps in your television owner’s manual for cable channel recognition (or channel scanning).If there has been a power interruption in your hall, the television set may have lost the memory function for cable channel selection. My television was working fine and now it is not getting any/all of the channels.
