I have a Canon 30V Date camera.All was working well until I recently made a trip to Canada during which the camera was put through the usual security scanner at the airport. On arrival in Canada the camera did not work and showed the batteries as dead. These were replaced with new but with the same result. The screen shows an empty battery when switched off but this disappears completely leaving the screen blank when the camera is switched on. Can the camera have been damaged by the security scaning?
