Before undertaking any replacement, try running a display diagnostic (hold the D key through powerup). You should see a series of self-test screens. If you do not, the display is faulty.
If you do see those tests, proceed to check the cable connection to the mainboard (the one to the display side isn't accessible). It may be the cable has worked loose. If not, replace the display assembly.

The cable is part of the display assembly, which cannot be disassembled -- if the cable is damaged, the display assembly needs to be replaced.

Hello, I have a similar problem.
As recommended, I held down the D key while rebooting and a sequence of full screen monocromes appeared on my display.
Moreover, I tried connecting the laptop to a second monitor: a black background appeared, but I could visualise and control the mouse pointer.
Any suggestions on the possible reason for this issue and how to possibly fix it?
Thank you in advance.
