With the recent switch to all-digital programming made by the federal government, all stations you watch are now completely digital. However, this does not necessarily mean you are not going to have a drop in signal quality. There are still issues that may arise, typically due to bad cable connections. Whatever the reason behind your bad digital television signal, it is possible to fix the issue with a few troubleshooting steps.

  1. 1

    Inspect the cable connection running from your cable or satellite receiver. Make sure that the cables are completely inserted into the connection ports.

  2. 2

    Remove the connection cables from the television and receiver and spray a few shots of compressed air into the connection points. If dust has built up on the ports, the audio and video quality may fail.

  3. 3

    Contact your satellite company. It is possible the satellite dish has been moved out of place due to the wind or precipitation. If the satellite dish is not positioned properly, most of your stations do not come in.

  4. 4

    Try out a different cable connection. If you are using a coaxial cable and there seems to be something wrong with the connection point, switch to RCA audio/video cables or component cables. These offer higher quality and may fix the issue with the bad connection.

  5. 5

    Move your antenna (if you are using an antenna based connection) away from your radio. If the TV antenna is near the radio antenna, it is possible to pick up radio station interference while viewing your programming.
