I've seen everyone mention everything from an app that's keeping the display on to a "car mode" being enabled. If doing a phone reboot (pulling out the battery) doesn't fix it then I'd say it has to be a setting somewhere. Best to do is to work backwards, ask her when it started and what apps she's downloaded since it worked. If she does backups, you can also try restoring to a previous date.
Oh and is she rooted?
