LCD backlight not working after screen change
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?
Is this a good question?
