camera wont stay on
camera wont stay on after power button is press, screen lights up for 3 seconds then camera beeps 3 times then shut down. the lens does not comes out and the battery indicator does not appear on the screen, this is not a battery problem as this problem keep reoccurring after returning from the technician. 3 times the technician looks on it each after a few picture problem reappear. thanks for your help
