Black screen / green vertical lines / software running

Question

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

It may be your Graphics card or the Display.

Try an SMC reset:

Try resetting NVRAM:

Try starting up in Safe Mode:

Run Apple Diagnostics

Press and hold the d key on startup:

If none of those work make a Genius Bar appointment for a free diagnostic:

Thanks for your prompt response.

I tried everything there using the power buttons and the keys as I cannot see what’s on the screen. You could tell there was a response by the computer but it unfortunately didn’t make a difference.

Any other ideas would be greatly appreciated. Thank you for your efforts.
