when ever I push the on/off button, the green light will come on, the camera will "chirp" and the display will come one ... but only for a moment and then the the camera will shut off before the lens extends...if I press and hold the "blue triangle in a box" button below the display while pressing the on/off button the display will function and I can view any pics on the memory... but thats it ! does anyone have any hints as to the problem?thank you
