hi i´m having problem with my lcd screen on my macbook 13" the screen fluctuates sometimes and goes out and to fix that i will have to rock the screen back and forth for about 2-3 cm this is getting really frustrating and i am not going to the apple store to get it fixed due to cost vs old computer is there no way i can fix it by my self ? it seems to be connection problems on the screen should be a easy fix i think has no one had this problem ?? before and is willing to share his wisdom !!
