Samsung Galaxy S20 Black Screen Repair

Troubleshooting a Black Screen on Your Samsung Galaxy S20

Is your Samsung Galaxy S20 screen not turning on? Don’t worry, we’ve got you covered. At Salvation Repair, we offer a limited lifetime guarantee on all parts and labor, and our expert technicians are here to help you diagnose and fix the issue. In this tutorial, we’ll walk you through the steps to troubleshoot a black screen on your Samsung Galaxy S20.

Samsung Galaxy S20 Black Screen

Before we begin, make sure you’ve tried the basics: charging your phone, checking for any blockages in the charging port, and ensuring that your screen isn’t just locked or in sleep mode.

Battery is Dead

If your phone’s battery is dead, it won’t be able to display any images on the screen. Try charging your phone using a USB-C cable or a wireless charging pad. If your phone still doesn’t turn on, it’s possible that the battery is faulty or the charging port is malfunctioning.

Dust Blower

Use a dust blower to clean out any debris from the charging port, and try charging your phone again. If it still doesn’t work, you may need to replace the battery or the charging port.

Firmware Malfunction

Temporary files, background processes, and system glitches can cause your Samsung Galaxy S20’s screen to go black and prevent an image from showing. To reset any firmware blips, you can perform a force restart on your phone.

To force restart the Galaxy S20, press and hold the Power button and the Volume down button simultaneously for 10 seconds. Release the buttons when the phone restarts.

Faulty Battery

Lithium-ion batteries like the one found in your Galaxy S20 are only rated for around 400-500 charge cycles before the battery capacity degrades to 80%. If you’ve been using your phone for 2-3+ years and have amassed a thousand or more charge cycles, your phone may have trouble starting the hardware up, even when fully charged.

Check your phone’s physical appearance for any signs of swelling or bulging. If you notice any, it’s likely that your battery is faulty and needs to be replaced.

Broken AMOLED Display

If you’ve eliminated discharged/faulty batteries and software issues as a cause for your faulty screen, the most likely culprit is a broken display. The OLED display on the Samsung Galaxy S20 is responsible for generating the images and colors on the screen.

If your screen has significant visible damage such as large cracks, or if your phone has been submerged for a substantial amount of time or at great depths, this may be the cause of your display degradation. In any case, you will likely want to replace the display assembly of your Galaxy S20 device.

Faulty Motherboard

Although a rarer case than a broken screen, it’s possible that a faulty motherboard is preventing the entire phone from functioning. Since the motherboard controls all of the processes of the phone, its malfunction would prevent the screen from displaying images or accepting touch input.
