Power/lens Problems

I'm having some power/lens problems with my camera. When I turn on the power in either the picture or video mode, the green light will turn on for a split second then turn off. The lens does not come out at all. However, when I try to turn it on with the picture viewer or in the menu it works just fine. When I start with the picture viewer and then switch to the camera it turns off. Thus it seems that whenever I want to take a picture or a movie the camera doesn't work. I've tried reseting the camera but this did nothing. I've also made sure the batteries are fully charged, and in the picture viewing mode the camera indicates the batteries are fully charged. This didn't help. I would appreciate any help that is out there. Cheers.
