How to Reset A Cable Box

The set-top box connected to your television delivers digital cable to the TV. If the cable box loses signal, fails to broadcast in high-definition -- despite having an HDTV and HD-compatible box -- or displays a pixelated or distorted image on some or all channels, the box might need to be reset. You can power-cycle the device as a troubleshooting method to see if the problem goes away.
