So, I just bought a Sony Bravia 52' LED 120hz 1080p TV, got a great deal on it from Walmart actually. Anyhow, it was one of the tv's they had on display there, the problem being that I think it's stuck in "Demo Mode" and I'm not sure how to turn it off. It didn't come with a remote, so I'm stuck using the side panel. Can anyone help me figure out how to take it off?
