Hi community - I recently did a main board swap. Everything seems to have worked, and when I turn on the machine I’m presented with a bitlocker screen to enter my key. Thing is, the screen is dark, really dark, and the brightness keys don’t do anything but the rest of the keyboard works. Seems to me like the backlight is off. I’ve opened it up and reseated the screen connector to the main board, but to no avail.
Any suggestions on what to troubleshoot?
