Panasonic DMC LZ5 shutting down continuously

Krishna sometimes the software in the camera get lost how I do not know. When you pass through metal detectors it can happen. If I put mine down on the car hood the fields of electricity under the hood will cause it not to work. Remove the batteries and wait at least a couple of minutes and put fresh ones or strongly recharged ones back in and it should stop the problem. You batteries could be at fault as well, if they are weak it will cause the same problem
