My Screen is cracked!

So just to be clear, it's only the protective screen cover that's cracked and not the screen itself? If so, it should be possible to replace it. That protective screen is held onto the back cover with double sided tape. The protective screen is called the TFT Window and the part number is CB5-3882. If the remaining tape isn't sticky enough after removing the window, you may also need to replace the tape. Often times the tape will be included if you buy a new protective screen, but if not, the part number for the tape is CB5-1039. Ideally you'd use the correct tape made for attaching the window to the camera, but you might also be able to use some other type of double sided tape if absolutely necessary.

I haven't done this repair personally, so I'm not certain on the proper way to remove the window. It might be possible to pry off the window without disassembling the camera at all, using something like a plastic pick (don't use anything metal). If it's not possible to just pry off the window without any disassembly, then this guide will show you how to disassemble what you need to in order to get at the window. It's for a different model, but the steps should mostly all match up pretty closely.

If you don't want to do the repair yourself, I'd imagine any camera repair shops that services this model of camera should be willing to do the repair for you as long as they are able to get ahold of a replacement window. If a replacement window can't be found, then the next solution would be to just replace the whole back cover, which would work, but also probably cost a bit more money.
