Zoom and shutter button doesn't work anymore

@kimora24 one good thing about the Coolpix L- series cameras is, that they are all very similar to disassemble. I would suggest that you take a look at the repair manual for the L20.You can find it now under the Documents Tab on this page Nikon Coolpix L20 Check your button bar and hopefully that is where the error is and not that you have cracked the top PCB.

If you have any problems taking your camera apart, you can always post some pictures of where the hang-up is :-) with your Question. That way we can see what you see and hopefully we can assist you in getting your camera working again. Adding images to an existing question

While you work on your camera, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
