Why is the backlight not working?
I just replaced the lcd of my macbook and now the backlight does not work. when I turn on the laptop, the lcd works but the backlight does not turn on. I tested with a couple of screens but no success.
Is the problem with the backlight LED, or fuse or logic board, is there any solution?
Model: Macbook air, 11 inches model A1370, 2011.
Any help would be highly appreciated
Questa è una buona domanda?
What are the last three of your serial number? that number will allow us to identify your computer and your motherboard a bit better.
When replacing an LCD u need to be really carefull and me personally don't recommend doing it yours self.
maybe u forgot one of the cables when closing it?
the last three letter of serial number are: JYC
all the cables are connected, the thing is that at the beginning i connected the backlight cable inversely, that might have missed up something...

Navid km, it does appear as if your MBA has a backlight fuse. "The fuse is on the same side as the LCD connector (upper left, looking at the logic board with the botom cover removed). It is near a small 6-pin chip (WLED driver?) and the fuse itself is very tiny with a white dot (or "P"" in the center).
Hi thanks for the nice replies,
I have to open the case and check the fuse on the motherboard, Can you please let me know where the WLED on the motherboard is and how to test it?
