I received an xbox360 from the repair center, but i cannot get auto-play to work with it. I have a game in the console and when i turn it on. I have to hit a button to launch it.
How do i set it up?
I already have auto-play enabled in settings
and auto-signon for one of my profiles.

You want it to start the game when you turn on the console? I think there is another setting, besides auto play, for that. I'm not at home, so I don't remember where it is exactly. I think there is a startup section in the settings. You can set it in there to either go to dashboard or auto play a disc on startup.
