on the top of the camera, there is a dial which says QUAL, WB and ISO. Look for button and ring just below this. It should say S, CL, CH, Lv, a clock and Mup. Press the button to release the ring and rotate it to the clock icon to activate self timer

I think the factory repair service is the best choice for this type repair. The El Segundo location worked well for me. You may be able to contact them by phone (number on the Nikon web site) and ask about cost, but if you ship the camera to them they will give you a quote before starting work.

Get the battery checked in a nikon customer care. See if the camera works with same nikon battery of the some other person. If not, the problem might lie with the camera. Visit the customer care for repairing it.
