Can you repair and replace the phone shattered LCD?

Bob, ifixit does not do repair. Here you can get parts and a lot of advice on how to fix it yourself. I am making the assumption that your phone is a Nokia Lumia 1520. If so, follow this video for a look at the disassembly and how to replace the LCD. The display assembly is available, although not cheap. You are looking at around $250 + for a replacement. Hope this helps, good luck.
