Is this a MacBook Air with a dead backlight fuse?

crwdns2934249:0crwdne2934249:0:

I have a MacBook Air 13” mid 2013 with a working screen but no backlight. This can be simply a dead fuse so I’m trying to avoid paying a hefty motherboard technician bill.

Upon opening the MacBook, I immediately notice 3 motherboard screws that have come loose and were attached around the LVDS area. This might have caused problems.

I go straight to the fuse close to the LVDS, assuming that’s the backlight fuse. I’ve done a diode and resistence test on this component. It seems dead: infinite resistence on both tests.

My questions:

* Have I measured the right fuse?
* Would simply replacing this fuse fix my backlight problem?
