i recently bought a samsung WB100 bridge camera from online, but when i turn it on, the lens comes out and in then again, then the camera turns off. sometimes the camera will start up no problem, sometimes, the Lens wont even come out. i replaced the batteries and it stopped for about 6 hours then started again. is it the camera? or the batteries? or what? the batteries are just single use panasonic AA batteries. Is there anyway i can stop this happening without returning the camera, as it would be a lot of hassle? thanks for answering :-)
