Black screen, laptop still has power. Was working on monitor.

Hi there.

So, yesterday I was working on my laptop with it hooked up to a monitor and all of a sudden the screen goes black, but not as if there was no power, it was still dimly lit but it wasn't showing any icons or anything.

Now, if I hook it up to my monitor and close the laptop lid, it will display fine on the monitor. But if I open the lid then the monitor display goes grey (but I can see and move the mouse curser) and the laptop display is still black.

Then today, it began working fine again until I tried to exit fullscreen from a YouTube video and then boom, black screen again.

If I start up the laptop I will hear the sound, the back apple logo lights up and the keyboard lights up, all as normal, only the display is black.

I have tried all the SMC and PRAM resets but to no avail. Anything else I can try? Maybe a loose connection since it started working again and then stopped? I am praying it is something that I can fix myself and don't have to fork out ££ for.

Little update - It now works when plugged into the monitor again. The laptop screen stays black, but I can use it to type and use the trackpad.

Sorry about your Mac! Attempt to first update your OS, as his may well be a bug.

When you had your computer plugged to a monitor, did the flickering carry over to it? Or was it only on the Mac’s built-in display?

Hey. Thanks for the reply. How would I go about updating it since I can't actually use the laptop?

Sorry could you explain the last part again? What do you mean by flickering?

No worries! So, if you connect a screen to your laptop, do you see the same flashing/flickering on the external screen?

Daniel Braun さんによる2019年2月21日

There is no flashing or flickering at all. The laptop screen is just black.

Okay, then this is likely a problem with the display module. You may want to try to reseat the display cable (as illustrated in Step 10 of this guide MacBook Pro 15インチ Retina Display Mid 2015のディスプレイアセンブリの交換 )

I will be honest: this isn't likely to fix the issue-- only rarely does this work. If this fails, you will need to replace the display on your Mac.

I'll give it a go. How much would it be to fix? Roughly?
