thanks very much to you both.
the walk though on ifixit covers removing the clam shell but doesn't go as far as getting inside it. I'm pretty sure it just needs a wire as it flickers on and off if I apply pressure to the left hand side of the screen. Don't seem to be able to find the cable seperate on ifixit.
Does anyone know who actually makes the screens, I could go to them and maybe get a cable?
