MacBook Air 2015: seems to boot normally, LCD screen does not turn on
My Macbook Air (A1466, 13 inch, early 2015) has a loose screen hinge, so I followed this guide for removing the display assembly, removed the black shroud (with some difficulty), and tightened the screws in the hinge. But when I reassembled the laptop, the screen will not turn on. I cannot see an image when I shine a flashlight through the translucent Apple logo on the back. The laptop seems to boot as normal: I hear the chime and I hear system sounds (such as when I insert a USB stick), and I can turn the keyboard backlight on and off. The laptop also seems to charge normally, since the LED is amber when I plug it in and turns green after a while.
I've previously replaced the SSD and the battery in this laptop, and the laptop worked fine after those repairs.
I've disassembled the laptop again (using this guide) and used a can of computer duster to blow out dust on the logic board and inside the connections. The pins on the connectors look okay. I cannot see any damage to the wires. I wiped the board with some 99% isopropyl alcohol.
I do not have a Thunderbolt adaptor to test with an external display.
