Before i describe my issue here is a little background first! On july 1 2010 i took in my 13" MBP to my local Apple Store in Novi Mi, for screen replacement. The screen had a bruise in the center so the Geniuses kindly offered to replace it. This is not the first screen replacement i had on this MBP, during the past two months i had the screen replaced 4 times. This morning i picked up my MBP turned it on to make sure everything was working properly. Nothing seemed wrong so i headed home. The Geniuses decided to also replace my logic board with a new one, thinking that it might solve my issue but no luck. Now for the real issue: From what i can tell it looks like screen tearing. I can't really describe the issue so i took a video to show you: http://s838.photobucket.com/albums/zz309/emiljanhaxhi/?action=view¤t=MOV01741.mp4 This started to happen when i got home. I powered on the MBP and went online to check my email. About 15min later this started to happen. I don't know whats causing it but i think the graphics card on the new logic board is faulty. I reset the pram and smc and no luck. This only happens after the mbp is on for a few minutes its not something that happens as soon as it boots up. Also when i close the lid and open it back up the screen if fine again, then a few minutes later the screen tearing comes back. I'm stumped on whats going on, so i thought i would ask here before i return to the apple store.
