Several things can cause the Galaxy M51 screen to stop showing anything while the phone itself keeps running.
Why Is My Samsung Galaxy M51 Screen Black?
Temporary Software Glitch
Android can occasionally freeze or fail to load the display properly. This can happen after an app crash, system error, or failed background process.
If the phone is still vibrating, ringing, or responding to button presses, a software glitch could be the reason.
Battery Completely Drained
Sometimes the phone may appear dead because the battery has dropped to a very low level. A faulty charger or cable can also prevent the battery from charging properly.
Try charging the phone for at least 20 to 30 minutes before testing it again.
Screen Damage
A drop or impact can damage the AMOLED display even if the glass does not look badly cracked. In such cases, the phone may continue working normally while the screen remains black.
Look for cracks, black spots, coloured lines, flickering, or any recent impact around the phone.
Loose Display Connection
The display connects to the phone’s motherboard through an internal connector. A strong drop can sometimes affect this connection.
This is not something you should try to fix at home. Opening the phone can cause further damage if you do not have the right tools or experience.
Water or Liquid Damage
Moisture can affect the display or internal components. If the black screen appeared after the phone came into contact with water, avoid repeatedly trying to switch it on or charge it.
Let the phone dry naturally and get the hardware checked if it does not recover.

How To Fix Samsung Galaxy M51 Screen Black Issue
Try these fixes in order. Start with the simple ones before considering a repair.
1. Force Restart Your Galaxy M51
A force restart is one of the first things to try if the screen suddenly goes black.
Press and hold the Power button and Volume Down button together for around 7 to 10 seconds. Keep holding them until the phone restarts.
If the issue was caused by a temporary software freeze, the display may return after the restart.
2. Charge The Phone Properly
Connect the Galaxy M51 to a working charger and leave it connected for at least 20 to 30 minutes.
Try a different charging cable or adapter if you have one available. Also check the charging port for visible dust or debris.
After charging, try the force restart again.
3. Check If The Phone Is Actually On
There are a few easy ways to check if the phone is running.
- Call your Galaxy M51 from another phone.
- Check if it vibrates when you press the power button.
- Connect it to a computer and see if the computer detects it.
- Listen for notification sounds.
- Check if the phone becomes warm during charging.
If the phone responds but the screen remains black, the display itself could be the problem.
4. Check For Physical Screen Damage
Think about what happened just before the issue started.
Did the phone fall? Was it pressed under something heavy? Did the screen develop lines or flicker before going completely black?
Even when the outer glass looks fine, an internal display failure can stop the screen from showing anything.
If the phone has suffered a recent impact, avoid pressing hard on the screen or trying to bend the device to get it working again.

5. Try Samsung’s Safe Mode
If the display comes back after a restart but keeps going black later, a recently installed app could be causing problems.
To test this, restart the phone and try entering Safe Mode. If the screen works normally in Safe Mode, recently installed or updated apps may be worth checking.
Uninstall suspicious apps one at a time and restart the phone normally after each removal.
6. Check For System Updates
If the screen works intermittently, check for available software updates under:
Settings > Software update > Download and install
An outdated or buggy system can sometimes cause display-related problems. Keep the phone updated once you regain access to the screen.
What If The Galaxy M51 Screen Is Still Black?
If the phone clearly turns on but none of the above fixes brings the display back, the problem may be hardware-related.
A damaged AMOLED panel, display connector, or another internal component could be responsible. At this stage, repeatedly restarting or charging the phone is unlikely to solve the issue.
A proper diagnosis can help identify whether the screen needs replacement or another internal repair.
