Vizio TV Volume Going Up and Down

Of all the audio-related issues Vizio TV owners face, this is the worst. The volume on their TVs constantly goes up/down like a yo-yo, causing them & their neighbors extreme distress. Here’s why this issue keeps happening with Vizio TVs:

  • The TV’s control switch is stuck/damaged  
  • There are problems with the remote control (e.g., one button was accidentally pressed too hard).
  • Your Vizio remote volume button is not working at all 
  • There are issues with your Vizio TV’s software
  • The TV’s audio has the wrong settings
  • There’s a conflict between your TV’s advanced audio settings & the program you’re trying to watch 

To address these issues, take the following steps:

  • Make sure all the wires & cables connected to your Vizio TV are in good shape.
  • Check whether any buttons on your TV’s remote are pressed or damaged; if yes – manually fix them. 
  • Review your TV’s audio settings.

In most cases, the last issue (conflict between the TV’s advanced audio settings & the programs being watched) is to blame. To fix this issue, you’ll need to turn off your Vizio TV’s advanced SRS TruVolume:

  • Enter the Main Menu
  • Enter Audio Settings
  • Enter Advanced Audio
  • Turn off SRS TruVolume

Applying one or many of these fixes will hopefully address your TV’s volume fluctuation issues. You can also try updating your TV’s firmware. Here’s a helpful video guide that further elaborates on this specific issue.

Inaudible Sound

Vizio sound not working at all is an issue many users complain about. If your Vizio TV has no sound, perform the following troubleshooting tricks –

  • Disconnect all connected devices (set-top boxes, gaming consoles, etc.) for a while to see if the issue is fixed. If yes, one of your connected devices could trigger your TV’s audio issues.
  • Make sure no cables connected to your TV are dirty or damaged. If they are, replace them to see if the audio issues still persist.
