Display not turning on. Also, Keyboard backlight not working.

I have a 2014 13” MBP that had coffee spilled on it. It will functions except a few keys do not work and the battery will not charge. I recently acquired a 2015MBP with a broken screen so I thought I would swap the screen to the 2015 and see if I could get it running. Since the cables were all the same I gave it a try. It wasn’t until I saw it didn’t work that I did some research and found that the video drivers were different. So I decided to swap it back to the 2014.

Well, now the display doesn’t work on the 2014. It still powers on, chimes and even works with an external display. I’ve checked the cable connections multiple times, did PRAM reset and SMC reset. The other thing is that the keyboard backlight does not work on the 2014. I don’t recall if it did before but is the controller for the keyboard backlight in the display? Could I have fried something in the display? I don’t see any image if I shine a bright light on the screen. So far I have $0 into this so I’m not too worried. I just don’t want to start throwing parts at it that cost me money.

Any help would be greatly appreciated.
Thanks,
Scott
