hi all. my macbook 3,1 Intel Core 2 Duo, 2.2 GHz has a problem and "i've had all i stand and i can't stands no more" (sorry popeye) ok heres the deal. my screen only lights up when i angle it towards the user (about 65 degrees or less) above that it goes dark. too dark to see. i was told that it could be a pinch in the cable or ribbon. how can i check and repair this.
