Apple products are notoriously hard to fix. 

As Apple designs its products to make them difficult to take apart and repair. In addition, Apple does not sell replacement parts for their products.

I would not advise trying to fix it yourself if you are unexperienced, your best bet is to bring it to an Apple Store or experienced third-party repair shop specializing in in Apple product repair.
