The pop up flash won't pop up. I've tried turning it off an on. I tried taking the battery out an putting it in again ( this worked the first time I had the problem, but doesn't any more. Any suggestions ?

Look at arms on the top cover were you can put a external flash sometimes they are bent and the flash thinks there is a external flash and won't open. Also if you look under the right side of the hot shoe flash you will see a little white piece sticking up under the arm that recognizes an external flash sometimes it gets dirty, some alcohol and a qtip will solve this. If that doesn't help reset the camera to the original settings. Put the camera in P mode go into the main menu and clear the custom functions and the camera settings and then with your nails grab the flash cover and then use your other hand and press the flash pop up button. Alot of times residue will get in between the top cover and flash cover. Again use alcohol and a q-tip and clean everything under the flash real good. Sometimes the arm is bent under the flash, it should be straight and rest forward slightly if it is bent use a pair of pliers with no teeth and straighting back into place! If none of this helps could you take a pic of the top of the camera with the flash closed and open and maybe I can see what is going on!
