Where are the channel buttons on a Vizio?

Big flat screen Vizio in out theatre room. Someone took the remote. Trying to find channel buttons on TV.
Thank you!

exact model of the vizio? might not have button on the tv, or could be on top bottom, back, etc

There are three different layouts depending on the model, a one button lower left rear that does everything, a set of buttons on side, and one with front touch buttons.
