Why doesn't LG Optimus G Pro screen turn on after I repaired it?
I just finished repairing my lense screen and after I assembled it my screen doesn't turn on? What can I do? Is it fixable?
Carefully inspect the LCD flex that connects to the board, or in this case I believe it connects to the charge port flex. Try applying a little pressure to it or check for any signs of laceration, if the flex is torn at all then the LCD is no longer good. I make the comment about the pressure because something similar happened with an LG G2 i fixed. No image on the LCD but when I would play with the flex the image would show.

Did you double check your work? Did you make sure everything is properly connected? Have you tried the old screen to make sure you have a working phone? Why did you replace the screen? what happened to your phone before?
