I have an old Late 2007 MacBook, it has been working until few days ago. Suddenly the backlighting of the display stopped working.
Basically I turn on the computer and the screen is almost dark.
If I point a lamp in front of the display, I can see the interface behind, however even at maximum brightness it's still dark.
I've contacted Apple support but they told me that there are no replacements of a machine that old.
I'm quite comfortable at opening it and try to fix by myself but I don't know what parts i need. What could be the issue?
