I just took the whole thing apart, pulled the screen cables through the frame more, put it all back and it's working now, I think the connector for the led, at the bottom was not lined up correctly. I tested before putting the case back on, and stil lines, tightened the led connector, working so far. Good luck with yours, I still think it's a faulty part
I just got the samething, I'm thinking maybe defective replacement part or faulty/broken connectors. Btw where did you buy your digitizer/lcd Amazon? I'm gonna wait to see if there's an easy fix before try returning the part.
