Part 1. Potential Causes of Macbook Pro Screen Goes Black
Battery Drain
Your Mac may be a workhorse but develops malfunctions with abuses like prolonged use. A defective battery or a faulty charging cord can unleash the dark screen nightmare. Check all hardware components related to the charging system.
Software/App Error

It's a strange cause, but sometimes junk files open a new can of worms, so it doesn't hurt to try this piece of software.
Broken Disk Permissions/Login Items

Waking from Sleep
Black screen problems also occur when rebooting your Mac from sleep. It may be caused by factory defects leading to a stubborn screen. Sometimes, the computer may respond with noises, active fans or indicator lights while the screen remains blank.
MacOS Operating System
The new operating system might trigger compatibility issues leading to a black screen. Similarly, macOS contains bugs that could produce the black screen of death. iMyMac PowerMyMac frees up system storage space to optimize performance. Reinstall the macOS and all apps to the latest versions to solve software issues.
Part 2. How to Fix Macbook Pro Screen Goes Black and Unresponsive
Method 1. PRAM Reset Your Mac
The first and most decisive way you can pull off this trick involves a PRAM reset. PRAM means ‘Parameter Random Access Memory'-a division of memory that archives system settings. Resetting the PRAM memory can help kill the black screen.
Step 1: Reboot and once you hear the sound; latch on Command + Option + P + R buttons.
Step 2: The next time the boot sound chimes, the PRAM is reset.
Step 3: Give the Mac time to boot up and check if the dark screen has disappeared.
Method 2. Reset the System Management Controller (SMC)
Trying to reset the SMC may do the job as it lies at the heart of your Mac system. SMC refers to an integrated circuit in charge of power management. Resetting SMC can fix the black screen. Follow the steps below.
Step 1: Switch off your mac and plug in the charger.
Step 2: Press down the Shift + Control + Option + Power keys at once for 5 seconds.
Step 3: Free all the button keys.
Step 4: Your Mac should now restart without the dark screen.
Method 3. Sleep with a Keypress Sequence
Next, boot up your Mac after sleep. This hack can work if the other methods above fail.
To do this:
Step 1: Hit the power off switch to throw up the dialogue box even though it remains cloaked in darkness.
Step 2: Press the S button, the shortcut for sleep.
Step 3: Latch on the power button for ten seconds to get out of the way.
Step 4: After 15 seconds, hold down the power button to reboot it.
Part 3. Other Solutions to Remove Macbook Pro Black Screen
Solution #1 Restarting
If you can't access the system metrics, restarting the machine may address the issue. Click CNTRL + EJECT keys to display the dialog box, then hit ENTER even where the dialog box is shrouded. Afterward, press the power button once the computer shuts down to restart it.
CNTRL+ CMND + EJECT automatically launches a restart. Latch on the power button for 5 seconds to screech it to a halt. Give it 15 seconds and hold it again to reboot. Your Mac should launch to its normal state without the black screen.

Solution #2 Reinstall MacOS

Solution #3 Hardware Problems
Where the issue requires a replacement of a hardware component like charging or battery, you have to fix this to remove the darkened screen. Check the current model and the serial number of equipment to order a compatible version. Incompatibilities can exacerbate system failures and increase the costs of repair.
Part 4. In Conclusion
Black screens throw a spanner in the works leaving you frustrated and confounded. The first and conclusive solution is to reboot your machine. If you can restart your machine without a clear display, this will counter the problem right off the bat.

Ciao, ho un Macbook pro retina mid 2015 dal 2017 (nuovo)(ovviamente è già fuori garanzia) , da ieri 15/03/2021 il macbook ha deciso di dare schermata nera. Collegandola tramite un cavo HDMI riesco a visualizzare il macbook tranquillamente, ma senza schermo esterno non saprei come fare dato che lo schermo nero rimane perennemente senza permettermi di vedere nulla. Fortunatamente funziona tutto, ma capite che la situazione è ingestibile, soprattutto per chi lavora come me. Dopo aver fatto diverse prove anche parlando con il centro assistenza Apple non siamo riusciti a trovare una soluzione. l'assistanza pensa che possa essere un problema hardware , e quindi chiedo a voi , quale potrebbe essere secondo voi il problema hardware di cui parlano? e in caso quanto mi verrebbe a costare il tutto?dato che il macbook funziona abbastanza bene potrebbe essere stato l'aggiornamento a BIGSURE che ho fatto verso dicembre? vi ringrazio in anticipo per la risposta , spero di risolvere dato che ho acquistato il macbook per lavoro e non per perdere tempo come gli altri pc. Grazie in anticipo spero di essere stato abbastanza chiaro nella spiegazione.

Hallo!Na een weekje mijn MacBook niet te hebben gebruikt, krijg ik hem niet meer aan de praat. Alvast dat dacht ik toch. Als ik met een zaklamp schijn en zeer goed kijk, zie ik dat mijn MacBook werkt. Ik heb zelfs mijn paswoord ingegeven en kon ontgrendelen. Echter werd mijn scherm niet helderder (ook niet wanneer ik mijn helderheid wou aanpassen). Voor de rest werkt mijn capslock lampje en de helderheid van de toetsen ook. Enig idee aan wat dit kan liggen? Alvast een dikke merci!

To check which peripheral device is the 'culprit', connect one peripheral device to your Mac at a time and test. If a single peripheral device doesn't cause the 'Mac keeps restarting' issue, you can try to connect two or more peripheral devices to your Mac and test.
- While if a kernel panic occurs later, it must be something wrong with the internal RAM or third-party hardware. If so, follow tip 2 to check the hardware.
Tip 2: Check the internal RAM and third-party hardware on your Mac
Step 1: Shut down your Mac.
Step 2: Remove the third-party RAM and internal hardware from your Mac. Reseat your Apple RAM if you get one. If not, reseat the RAM you have instead.
Step 3: Start your Mac and use it as usual.
Step 4: Do troubleshooting.
- If the 'Mac keeps restarting' problem doesn't happen after you use your Mac for a period of time, you know that the third-party RAM or third-party internal hardware should to replaced to avoid the kernel panic.
- If your Mac keeps restarting again, you need to go to the Apple Store nearby with your Mac to seek help from Apple.
For software related kernel panic:
