My tv has no sound all of a sudden - Televison & Video

Check the obvious first, such as whether the mute button is on or whether the volume is turned down. If that's not the issue, try the following:

1. Verify that all of the cables are firmly seated by reinserting each one. Loss of sound from bumping into equipment is common, especially if your TV is connected to a sound system. You need tight connections to hear the audio.

2. Make sure the cords are connected correctly. Some TVs have color-coded inputs that can be matched up with cable boxes and sound systems.

3. Try a new cable to see if that fixes the problem. Over time, cables can malfunction too.

4. Make sure the remote is set to 1) the proper video input (TV, satellite/cable) and the correct audio input.

5. Check all channels to make sure it's not a TV provider issue. You can also call your provider first and make sure the problem doesn't originate with them and not your TV.

6. If you have an external sound system, test another input such as a radio, CD player or game console.
