Default Vizio 55" M550SL No volume up or down

Hello, and how is everybody doing? This Vizio's volume controls don't work on the tv and the remote... I don't yet have this tv, its waiting to be picked up... I'm wondering if this could be firmware or stuck, bad button on the televisions button panel...
