Fixing Samsung Galaxy Phone Black Screen
Fixing a Samsung Phone with a Black Screen
Before diving into the more time-consuming solutions, let’s cover some basics. If your phone’s battery is severely discharged, it may not show any signs of power for an extended period.
The front-facing camera and various sensors, including the Ambient Light Sensor (ALS), are located on the top edge of most Samsung phones. The ALS sets the screen’s auto brightness. If it’s malfunctioning, the screen might not be black, just dim.
Although most display failures seem obvious, the display may not work properly due to internal issues, even without visible damage.
The motherboard is the hub for most of your phone’s functionality. Any of the small components on the board may have failed or become damaged. It’s a safe assumption of cause if nothing else has worked.
Lime the main interconnect cables that run across the battery in many models, the display connects are often very wide.
Here are six common problems you might encounter:
1. A black screen can be caused by a malfunctioning Ambient Light Sensor (ALS).
2. A severely discharged battery may not show any signs of power.
3. Internal display failures can occur without visible damage.
4. Motherboard damage can cause a range of issues, including a black screen.
5. Faulty interconnect cables can prevent the display from working properly.
6. A malfunctioning front-facing camera can cause issues with the screen.
