Replacing LCD display cable

Hello, few days ago the LCD of my camera stopped working. I tried to understand what was going on, and I noted that it depends on the position of the LCD display: when the display is in a precise position, it works normally, otherwise I cannot see a thing (but I can still see the baklight). I followed the ifixit instructions to disassemble the camera (just the step 18), and I found that the thin cable of the LCD display is damaged, it has a cut in the exact point in which it curves (and this explain why in a precise position the display was working).

Is there a way to replace only the LCD cable (hoping that the problem is only that)? Or I have to replace the entire LCD display? The camera is no longer under warranty, so could you please let me know where I can fing spare parts on the internet?

Thank you a lot!
