LG G3 屏幕更换

Did you get it working i have the same issue? the picture displays with the original screen but not with the new one. i have tried 3 different screens and get the same on all of them. i even tried updating to the latest software but only get a black screen, no picture.

When i have had this on iphones i just so a reset by holding down the buttons and the screen starts to work.

Please someone help
