Power switch samsung nx2000

Power switch of my samsung nx2000 camera was stuck after I dropped my coffee on it accidently. from that day I needed to push it a little bit hard to make it on. It 's working for a few month. But Now it is loose and I cannot turn on my camera. I want to fix it by myself due to no samsung camera service center anymore in my place, Bali, Indonesia. Are there someone can solve my problem? Thanks
