I have a Samsung Galaxy J7 (2016) J7108. The LCD screen broke, so i decided to buy a replacement LCD screen. It arrived, i installed very carefully in my phone. But the problem is, it doens't work. The phone works, cause I can feel vibrations etc. But the screen just stays black. Is it maybe because I bought a screen for a J7 (2016) J710? Because mine is a j7108 version. The screen fit perfectly fine. I also tried reconnecting the screen etc, still didn't work.
