How can I fix a sunken power button on a JXD S7800b?

I dropped my Jxd on its side and so the power button has sunken. I have no way to press it. I managed to pop it out a little but it will not stick out like it use to. Even then it still doesn't press down or there is no reaction or clicking feeling anymore it's just loose and sunken. I opened it up fully and i can't seem to see what's the problem as I don't have experience. If I were to take a wild guess, it looks like it was crushed but I still intact. Maybe it was sodered on there? Not sure. I don't even know how to remove it. I can take pictures if they allow me to on this website. Email me @ themonsterhunterg@gmail.com if you would like to help :/ thanks I'd greatly appreciate it!
