Why did the sound go out

No Sound Troubleshooting Tips

1. Check Volume & Mute Settings
   • Make sure the TV volume isn’t muted or set too low.
   • Verify the remote control is working properly (try the physical buttons on the TV too).
2. Input Source Settings
   • Confirm the correct input is selected (HDMI, AV, Component, etc.).
   • If using HDMI, try a different port or cable to rule out a bad connection.
3. Audio Output Settings
   • Go into the TV’s audio menu and check if the speakers are set to “On.”
   • If using external speakers or a soundbar, ensure the TV is set to output audio through the correct port (optical, RCA, etc.).
4. External Speaker Jack
   • The E422AR has an optical audio output and RCA stereo outputs.
   • If connected to external speakers, make sure cables are secure and the external device is powered on.
5. Firmware Updates
   • Check if a firmware update is available through VIZIO’s support site. Updates can sometimes fix audio bugs.
6. Factory Reset
   • If settings got corrupted, perform a factory reset from the TV’s menu.
   • This will restore default audio settings and clear glitches.
7. Test with Different Devices
8. Plug in a DVD player, game console, or streaming stick to see if the issue is with the TV or the original source device.
