We have a sticky post about Air's backlight problems.

As fuse was burnt, check for short to ground on backlight circuitry.
Also check XW7720 integrity.
I am sorry , i am a bit Dumb.

Can you tell me how to " check XW7720 integrity "?

There is nothing shorted in that Area, I am not sure why fuse blown out
