I've got an aluminium 08 unibody macbook (I suppose an 'equivalent' of the macbook pro). Recently, I'm having issues with the display. As the pictures below show, there's a 'bar' of distortion, running vertically down the screen. If I wiggle the screen, it can sometimes alleviate it, but if I knock the screen again, it'll reappear. It's a bit of pain. Can anyone suggest which part of the innards I should clean? I tried taking the back off and cleaning away the dust, but it made no difference. I assume maybe it's a loose connection somewhere, but I don't which display connector to unplug and reconnect. Any tips/tutorials would be great, I don't really know what to search for.
