camera will only turn on when on gallery mode

i bought this camera at a yard sale yesterday, when i got home i put two fresh AA batteries and it worked flawlessly, then later when i tried to use it again it wouldnt turn on, the LED’s would all blink and the power on sound would start but cut off immediately, i tried a few things but none of them worked, i did find that it will turn on when its on gallery mode but will immediately shut down when i try to put it on any other mode. how can i fix this?
