Press pause button and hold down while turning off machine.Continue to hold pause button and turn power back on. If numbers come up on display make note of them for future reference. Release pause button and all lights on display will light up. Turn power off again and then turn back on. If machine was in a cycle it should end it and then return to normal operation. .Dont know if new lock made a difference. Try the reset procedure first.

hi,
seems like a silly question, and i dont know about canon copiers, but on my toshiba, underneath the key panel there is a scroll button that turns the brightness of the lcd up and down, if hit by accident, as often happens the lcd appears black. It has tricked me before!! haha
Take care
