Default [Q] Replacement parts

Hello all I was wondering if anyone could help me in finding some replacement parts for my oppo find 7a. So what happened was the very tip of the 3.5mm audio jack on my POS headphones stuck in my phone while the rest of it came out. No matter what I did I couldn't get it out. It prevented me from making calls or obviously using the jack for headphones.

So I took it apart. I successfully removed it but in putting it back together the little button that actuates the power switch was not in place so I couldn't control the power button. I went back in and managed to break it off. One tiny little piece of plastic and the entire phone is now useless. So I was hoping someone could point me in the right direction of ordering a replacement part. I think I will have to order an entirely new little circuit board. I haven't found anything on Oppo's site, could anyone help me out?
