Black screen / green vertical lines / software running
Hi all,
Got a dreaded black screen on my laptop when I turn it on and it stays that way. When I manually turn the laptop off, the screen turns off. There are visible green lines which change when the screen it turned on and off but stay green and vertical. Picture attached. 2017 MacBook Pro.
Obviously I will be taking it to an Apple retailer to see if they can fix but can anyone help me with an idea of what the issue might be and more importantly, the cost!
Thanks.
MacBook
