Long story short, i changed the thermal paste on my macbook pro as it was running hotter and hotter (as a matter of fact...

Ok, end of the story... IT WAS THE CABLE! Today i changed it and all is working again. Not a easy fix for a non professional like me, but i managed to tear the screen down without breaking anything (screen only half an hour in a 75°C oven, the glass came very well with a guitar pick and a small succion cup to help pulling), and put it back together quite clean. I'm very happy, end of a little nightmare... So what i learned: Those cables are fragile as happiness. If you have to disconnect it you have to be extra careful. I advise you to take away the cable holder to have a little more freedom of movement. It's just a phillips to unscrew and it could spare you ten days of sorrow and an afternoon of wobbling knees! (by the way, excuse any bad english, i'm french...)

Hi, since i got the exact same problem (only difference is that i checked the display socket with magnifier and it seems absolutely intact) i wonder if you found a solution. Was it the cable? Thanks
