Macbook air, 11 inches backlight not working after lcd replacement I just replaced the screen of my macbook air and now the backlight does not work. When I turn on the laptop, the screen works but the backlight does not turn on. I've 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.
You'll have a much better vantage point than us on the internet to guess.

First, reconnect all cables and hope it's that.

If not, you'll need to start replacing parts one by one. The odds of a new LCD being faulty are low - but the circumstances of the repair might help.

Was the LCD out the reason you swapped the panel?

You might need a second machine to isolate each part - test whether it's the cable, inverter, logic board LCD or something else.
