Hey, I had a cracked touch screen, and I bought a new screen(with LCD and touch screen).
After replacing the screen, I'm getting a black screen.
tried to disconnect the battery and return it, - not working
reset - not working
return the old screen(which have working LCD ) - not working- seeing black screen
Connect to HDMI - everything is working well.
What can I do next? All flex cable and connections look excellent
