Will not come on. Took it out of the case and the lens was open so I pushed it back in to close the lens and the batteries are good but still not working.

There is a gear drive that moves the lens, so you may have dislodged the teeth of the gear. There are several things you can try to fix this problem. First of all, make sure the battery is freshly and fully charged. and the camera is off. Remove the memory card, hold the camera (lens pointing down), press the replay or image review button and hold it down then press the Power On button. That does a hard reset on many Nikon cameras. Release the buttons after the camera powers up. Try the lens to see if that fixed it. If it did not, power the camera off, plug the AV cord into the AV jack, hold the camera with the lens down and power the camera on. Having the AV cable plugged in prevents the screen from powering up and gets more power to the lens motor. If this still doesn't fix the stuck lens there are three more things you may try. Hold the camera with the lens down and power off. Press the shutter button down, hold it, and then power up the camera. If there is movement and the lens still doesn't come all the way out, try this a couple more times If there is no success, the next two attempts should be tried knowing they may damage the camera more, but also may fix the problem. If the cost of repairing the camera is close to or exceeds the cost of the camera, these are worth a try. Remove the AV cable, power down the camera. holding the camera by the sides on one end, lens pointing down,
press the power on button and immediate strike the camera into your cupped empty hand fairly hard several times. See if that freed the lens. If not the last try will be the same except this time place a handkerchief folded several times for padding on a table or desk top and strike the free end of the camera on the folded handkerchief fairly hard to try to dislodge the lens. The only other
thing I could suggest you trying as a totally last resort would be to remove the battery and try to gently pry the lens up a little at a time moving the pry tool around the lens a little at a time. If you can raise it to the point you can grasp it, pull it to the extended position and make sure it is straight, rock the lens a tiny bit left to right and see if you hear a click. Sometimes that will reset the pins. Good luck. If none of this helps, you are going to need a new camera.
