Having your phone turn on but the screen won't light up can be worrying and frustrating. This article will help you find out the cause and provide effective solutions!

Fix the error of the phone turning on but not displaying the screen easily

The problem of the device turning on but the screen not lighting up is a common and annoying problem. This error can be caused by many things, from software to hardware. Below are instructions on effective solutions to get your device working normally again.

Restart your computer

A simple way to fix the problem of the phone turning on but the screen not lighting up is to restart the device. This problem can be caused by a system freeze or software conflict, causing the screen to not work even though the phone is still on.

Press and hold the power button for at least 10 seconds until the phone turns off completely, then turn it back on. Restarting helps the system recover, free up temporary memory, and fix software conflicts, so the screen will display normally again.

Use genuine charger

To fix the problem of the phone turning on but the screen not lighting up, make sure you are using the original charger. Non-genuine or poor quality chargers can provide unstable power supply, causing problems for the device.

Using a genuine charger ensures a sufficient and stable power supply, helps avoid undercharging and protects internal components. If the phone does not turn on the screen when using an unknown charger, try switching to a genuine charger to keep the device working normally and avoid damage to the device.

Remove the application causing the error immediately

There are some applications that are incompatible or contain malicious code that can conflict with the operating system, leading to the situation where the device turns on but the screen does not light up. To fix this, remove or disable third-party applications. This helps restore normal operation to the phone and improve screen display without having to intervene deeply into the system.

Remove the screen protector on your device.

Screen protectors are often used to protect phones from scratches and cracks. However, after a period of use, especially when moving in a pocket, the protector can become dented, peeled or cracked. This damage can cause discomfort and affect the touch when operating the device.

If your phone turns on but the screen won't light up, try removing the screen protector and checking for debris that's blocking the touch. Removing the old screen protector may help restore the display and improve your experience.

Replace the battery for the device

If you experience a sudden drop in battery power while using your phone, this may indicate that the battery is worn out or damaged, resulting in the phone turning on but the screen not displaying anything. For phones with removable batteries, remove the battery to check. If the battery is swollen, this is a clear sign of damage.

To ensure the safety and performance of your device, you need to replace the battery. If the device is still under warranty, take it to a warranty center. If not, take the device to a reputable repair center to replace the battery.

Replace phone screen

Another reason why your phone turns on but the screen does not light up could be that the screen is damaged. In this case, you should take your device to a reputable repair center for a thorough inspection by a technician. Depending on the extent of the damage, different measures may be required, such as repairing the socket, replacing the screen, or dealing with IC-related errors on the mainboard. A thorough inspection will help determine the appropriate solution, allowing you to continue using your phone normally.

Replace motherboard for machine

The motherboard is an important part of the phone, containing components such as memory and camera, and ensuring the stable operation of the device. If the phone turns on but does not display the screen, the problem may be on the motherboard. In many cases, replacing the motherboard is necessary. To solve the problem, you should take the phone to a reputable repair center for technicians to check and replace the motherboard if necessary.

The article has provided information on the causes and solutions for the situation where the phone turns on but the screen does not light up. These solutions will help you effectively handle and optimize screen-related problems.
