A black screen is one of the fears every smartphone user has, “I was using my phone at night but when I woke up the screen was just black. I tried locking and unlocking my phone but the screen is still black, what may be the issue?” a concerned customer asked after experiencing black screen. Though it is not a common issue, it can really stress you.
Black screen can be caused by various issues which makes the repair process to be complex since all issues must be examined to ensure the problem does not keep recurring. Since Carlcare is the authorized after sales service provider for TECNO users, our trained technicians have the experience and professionalism to sort out all your TECNO phone black screen issues.
These are some factors that could potentially lead to black phone screen.
Drained battery
Sometimes the simplest solution is the best one. Maybe you plugged in your charger but did not switch on the power source when charging, hence, your phone does not respond and has a black screen. If your charger or cable is damaged, the phone will not charge. Besides, sometimes if the charger or cable is not the original one, you may also experience black screen issues too.
Battery contact
If your device has a removable battery, you should check if the battery is in contact with the phone. A battery mostly loses contact to the pone after a hard drop or fall.
Screen failure
Sometimes black screen happens just because your screen has some issues. For example, the cables that connect the screen to the motherboard may be loose or spoiled. This can happen if your phone falls hard, even if your screen is not broken, the connecting cables might be damaged, thus causing the screen to become black.
Software damage
A software glitch can cause a lot of panic since most smartphone users do not know about them. Glitches can happen at any time and they make your device work in a strange way. Viruses and malwares also can invade your device and cause the screen to be black
Liquid damage
Liquids are the greatest enemy to electric devices. Once the water gets into contact with the internal hardware parts in a phone, it could cause short circuit, causing the electric current to flow in directions that it was not intended to. When the current does not flow through the screen properly, your screen immediately becomes black.
Dirt and Dust
If your phone fell in dirt, the dirt may have gone into your device and is blocking essential connections like the connection between the battery and motherboard or screen and motherboard. This also happens if you expose your device to dust. Even though you clean the phone but some dust particles can potentially damage the electric parts inside your phone.
