Olympus D-460 Digital Camera Trouble

[DellHop]

Does anyone have an Olympus D-460 Digital Camera. If so have you had an issue with the camera shutting off and not closing. I think i may have hit a lock button and I dont know how to unlock it. The camera doesnt respond to any thing. The lens stays extended, all screens are blank and it doesn't respond to any buttons being pressed. Any help would be greatly apreciated. Thanks
