"My camera won't turn on" için yanıthi there. i was having the same problem and there was a red light by the lens. i used two brand new energiser batteries straight out of the packet. after reading the above comment i realised my second battery was the wrong way around. i switched it and it took about two seconds for it to turn on, and now it’s perfectly normal again. i would very much recommend checking where the battery’s positive and negeative is.
