Causes of a Blank or Black Display

A blank or black screen can be caused by several factors, some of which are hardware-related. These include a depleted battery, a faulty charger, or physical damage to the phone or tablet. Sometimes, the problem might be due to a software glitch or a severe system crash.

Depleted Battery or Faulty Charger

A dead battery is one of the most common causes of a blank or black screen. If the device’s battery is completely drained, the screen cannot turn on. Similarly, a faulty charger can prevent the battery from charging, leading to the same result. You can check whether this is the problem by trying a different charger and cable, preferably one that you know works well.

Physical or Liquid Damage

Physical damage to the device, such as a drop or impact, can also cause a blank or black screen. Moreover, liquid damage can harm electronic devices, leading to various issues, including display problems. To check for physical or liquid damage, inspect your device carefully. Look for any visible signs of damage, like cracks, dents, or corrosion, especially around the USB connections and charging port.

You can also check the Liquid Damage Indicator (LDI) on Samsung devices, typically located in the SIM card slot. A solid white or white with pink or purple X’s LDI suggests no liquid damage, while a red, pink, or purplish-red LDI usually indicates that the device has been exposed to liquid.

How to Troubleshoot a Blank or Black Screen

If you’re facing a blank or black screen issue, here’s a step-by-step guide on how to troubleshoot it:

1. Inspect the Device and Its Accessories: Check your device, charger, and USB cable for any signs of physical or liquid damage. Remove any cases or accessories that might obstruct the charging port or buttons.
2. Force a Restart: Sometimes, forcing a restart can solve many issues, including a blank screen. To do this, press and hold the Power key (or Side key) and Volume down key for about 20 seconds. If your device has a removable battery, you can also try removing it for 60 seconds and reinserting it.
3. Charge the Device: Connect your device to the charger and charge it for at least an hour. The battery charging indicator may take up to 10 minutes to appear on the display, so don’t worry if you don’t see it immediately.
4. Try Turning the Device On: After charging, disconnect your device and try turning it on by pressing and holding the Power key (or Side key) for 15-20 seconds. If you see the Samsung Galaxy logo, your device must be charged.

If the above steps don’t resolve the problem, your device might need professional service. In such cases, it is recommended to contact Samsung Support Center for further assistance.

Remember, while a blank or black screen can be frustrating, it doesn’t always mean your device is permanently damaged.
