my camera always turns off and on continuously, initially my camera has not been used for a long time and I kept it in the cupboard safely, now I want to use the camera again but it seems the battery is dead so I charge the battery as usual, after a few hours I want to put the battery back into the camera, after I put the battery in the camera turns off and on continuously, I can also see at a glance that the lens is fine but the camera always turns off and on, and the camera can only turn off when I take the battery out, I have tried various ways but it is useless
