Hello Guys,

I have a Sony Xperia Z4 Tablet, Model: SGP771. After changing a cracked screen, with a brand new original Sony screen, the screen work but it doesn't light up. I mean it shows information and the touch sensor works, but the LCD light is not working.

I tried two different screens, and i get the same problem.

Any idea or suggestion with it?
