There are many reasons why your phone screen won’t turn on. Unless you dropped the phone or spilled something on it, it can be hard to tell if it’s a hardware or a software issue.
How to Fix a Broken Phone Screen That Won’t Turn On
Follow the troubleshooting tips below in order to get your phone up and running again. The tips in this article can work on tablets as well.
Check For Signs of Physical Damage
You may not remember a clear accident that may have damaged your phone, but it can still happen. Was your phone exposed to hot or freezing temperatures? Was it exposed to any liquids? Very small amounts of liquid, such as from sweat, can still damage the device.
Leaving the phone in your pocket is a generally bad idea, as it can bend out of shape.
If the charger was plugged in forcefully, the port may be damaged. This can prevent you from charging your phone.
Letting an overheating phone cool off can be all that is needed for it to restart. The same can apply to a damp phone that was left to dry off.
However, most physical damage to your device will require a visit to the repair shop.
Fix the Power Button
Check to see if the power button is broken, stuck, or unstable. If it’s stuck, you can try cleaning around it with a dry cloth or a toothbrush.
A problem with the power button is a reason to visit the repair shop. For one, it’s likely the reason why you can’t turn on the device. Even if it’s not, it will make troubleshooting significantly more difficult because you may need to reset your phone multiple times.
If your power button is fine, keep reading.
Restart your phone
On most devices, you can do this with a long press on the power button. It should take about 5-7 seconds. Try turning on the phone again after that.
If your phone case can be opened easily, remove the battery for about 10 seconds and put it back in. Hold the power button.
If nothing happens, or if the screen flashes for a moment then turns off again, keep reading.
Charge Your Phone
If available, use the charger and cable that came with your phone. Try them on a different device to make sure they’re working. If they don’t charge the other device, try a different outlet.
Try different outlets, chargers, and cables until you find a combination that works on different devices. Once you do, plug in the phone in question.
Make sure there’s no dust or other particles in the charging port, and that no phone accessories are pressing any of the buttons. If you’re not sure, remove all accessories such as phone covers, screen protectors, medals, etc…
Leave the phone to charge for at least 30 minutes before trying anything else.
My Phone Won’t Turn On When it’s Fully Charged!
Sometimes your phone is charging fine, but it still won’t turn on. Follow the steps below for a potential fix.
Troubleshoot The Screen
If you don’t see a battery icon while the phone is charging, it could mean that your screen is the culprit. To see if your phone is working otherwise, try pressing the power button for 30 seconds, then wait for about 2 minutes. Press the volume-up button a few times.
During this process, listen for any sounds that your phone may make. If you don’t hear anything, use another device to call your phone.
If you hear any sounds, it means that your phone is working, but the problem is with the screen. In this case, you may need to have the screen replaced.
If you don’t hear anything, keep reading.
Try the Safe Mode
The buttons for the ‘safe mode’ can vary by device. Try turning on your phone, waiting for about 5 seconds, then pressing and holding the power down button.
If you’re not sure about the exact button combination for your device, look up your phone’s model, check the manual, or contact the manufacturer.
If your phone boots up in safe mode, it means that one of the apps you have installed may be responsible for the problem.
Remove recently-installed apps, then restart your phone normally. You can do this for each individual app until you find the corrupted one.
While in safe mode, you can also try resetting your device to factory settings. This will erase all of the installed apps and data in the internal memory and will reset all the settings. Restoring to factory settings is a great way to get rid of any malware if it exists.
If the device didn’t start with safe mode, keep reading.
Sometimes the software on your device can get corrupted due to system tweaks. For example, if an update was interrupted.
In this case, you can try reinstalling the firmware for your device. The correct firmware will depend on the make and model of your phone. Most likely, you’ll need to connect your phone to a laptop or PC and to install special software that will install the firmware for you.
Replace The Battery
If you’ve had the phone for a while, the battery may need to be replaced. Lithium-ion batteries are very durable, but they can only be recharged so many times before their capacities begin to degrade.
An old Lithium-ion battery may show that it’s 100% recharged, even when it’s not.
It’s actually rare that a battery becomes 100% unusable. Usually, you’ll notice that you need to charge your phone more often. It won’t die out completely all of a sudden.
If your phone case can’t be opened easily, it’s better to take it to a repair shop. A professional would know how to open it without damaging any parts.
If All else Fails
Have the phone looked at by a professional.
Sometimes phones just die out, and there’s nothing much you can do about it. If it’s new, you can contact the manufacturer for a replacement, or at least discuss the terms of their warranty. It’s possible that your device, in particular, is defective.
