jdc2000 is correct, the Keyboard wires would not run up to the screen.
It should be connected to the Motherboard which is below the keyboard.
There's normally a Ribbon Cable that connects the Keyboard to the motherboard.
Hopefully you can find something in the Links jdc2000 supplied.
Replacing that Keyboard could be a real PITA.

Been a long time since I really had to tear down a Laptop.
The keyboards used to be much easier to replace quite a few years ago.
