MacBook Pro early 2015 screen swap fail

Hello everyone I swap a working screen from a MacBook Pro to a new one, the screen was fully working before the swap, So I check the old screen cracked and it’s working on the new computer. I don’t know why the new screen it’s not working. Also I check and the screen cable has a code and it’s different one to another. Both MacBooks are early 2015 why the swap doesn’t work?
