It works but I am afraid to pull the display cable. It's too strong and i am constantly afraid I might break it and even break the motherboard by pulling it. I tried to pull a little hard and the mother board made a small noise and I thought it was sound of breaking. So, I stopped. Thanks for the guide but I will still take to a repair shop.
Did they have the scream on hand or was it hard to get when you took it to the shop?
