Hello~ I've got a 13-Inch MacBook 467, Late 2008. The first generation of the Uni-body MacBooks. Now, I met such display problem... I think there's something wrong with graphics card at first time ,but the display problem won't happen if I use the external display through the Mini-Display port to D-sub. If I rotate the clutch cover ,the display problem will disappear sometime. I doubt if there is something wrong with the display cable,but after I replaced the cable, the display problem is there still... Anyone ever who know what's the problem on earth ? Thank you.
