Hello, I've come here on an off while being a mac owner while looking for the proper upgrade to this very mac. I recently (last year) had my screen broken by my college roommate and got it replaced. About a month ago it just started shutting off randomly, so I sent it away to get fixed at a local apple store. After about a month I got it back saying it was fixed but quickly realized it wasn't, so I took it apart myself and noticed a frayed cord that when pushed back together fixes the issue. Here is a picture of where the cord is, and i'm wondering what my best option is? Edit: circled where the cord is frayed, directly under where those screws are.
