Can I repair the screen

@gustgoris sure you can. Use something like this video to at least get you into your calculator. Or you can check this site for some really good instructions. Written in French so you may need a translator for that :-) You may need to do an extensive online search for a replacement screen. Places like Alibaba.com or Taobao.com might yield results to get a new display.

While you replace your screen, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
