Hi all,
I have a mac book pro from mid 2008
The machine works perfectly and i am very happy, would like to keep it.
But the screen has started to behave strangely:

The problem come and goes by moving the display or patting it on the side
I've looked into the other posts but haven't found something like my case.
What do you guys think the problem is?
- lcd
- cable
-...
Thank you
