when on it automatically off
i on the camera its automatic off == ==
@mominashfaq10 , Momin, Poor/low batteries can shut down camera, replace batteries with good quality batteries, Duracell Alkaline, EverReady Lithium, etc. or ensure batteries are fully charged.
Check the settings camera has an Auto-Off function, camera can turn off after a period of time when not being used in order to save power. If too cold of environment the camera could do this, try warming camera back to room temperature. If shutting down after a lot of usage, camera may be overheating/could be a bad internal fault/component needing serviced. Let camera cool down and try again. Use the link to manual below to help trouble shoot your camera. Good luck.
