My Dell Latitude E5470's monitor stopped working a few weeks ago. After a few days of testing it with an external monitor I realized there was a shadow of the screen and if I put a light beside it I could see a little bit of what's on the screen. I took out the screen along with the eDP LCD cable and tried it on another laptop of the same model and the LCD turned on fine. Next I plugged in the other laptop's screen to my laptop's eDP port and it had the same problem. I have tried various things such as: raising the brightness inside windows and in the BIOS, running Windows from and external drive, running multiple diagnostics, and at last I dropped it off with a technician and he thinks it's either a hardware issue or the wire but again I tried my screen along with its wire on a different laptop and it worked fine and another laptop's screen had the same issue on mine. 

I am open to all suggestions as I'm trying to save some money and not purchase another laptop.
