swapping display data cables, is it possible/the solution?

i have a cracked display with a display data connection that is functional (everything shows up fine on parts of the screen not cracked) and i have another "grade A used" display assembly that i installed and it wont turn on.

the camera and airport antenna are functional and the system report shows that the display is the correct one, however, screen is still black (on the used replacement display). tried smc reset, control+option+p+r reset, adjust brightness, reseating the display data connection (4 times) and still black screen.

i put the cracked display back on to see if i damaged the display data input connection and the cracked display connects just as it did before. so i am thinking its the display data cable on the replacement causing trouble.

is it feasible to swap the cracked display's cable into the replacement assembly? or is there another element i am overlooking in the troubleshooting process?

thanks for your time and help!
