Phone powers up but it has a blank screen

I attempted to replace my speaker; in the process I broke some of the wire tips that connect the screen to the phone internal storage. Now the screen does not come on but it does vibrate when I power the phone on. It also makes the connection sound when I plug it in to a computer but it does not show the icon of the phone storage connected to the pc. Is there any way to retrieve all my files and pictures from the phone internal storage?
