Hi dear friends ! I have a new problem with my macbook 13 aluminium, I bought it in dec 2008! some times the screen goes black unexpectedly and if I move the screen it goes back to its noramal condition ! I went to the apple store and they said that it is for the connector of LCD ! what do you suggest guys !? what can I fix this problem ? do you know anything about the technology of this macbook's LCDs ?! can I fix it by myself ?!
