Consumer Tech: How I fixed my Samsung Galaxy A51 Black Screen of Death

Intro

After its customary overnight charging my A51 simply showed me a black screen in the morning. Yet I felt something was there because when I plugged it into the computer’s USB port the device was recognized. I was very concerned. But I did manage to completely fix it!

The symptoms

So various sites address this problem and give somewhat different advice. I sort of needed to combine them. So let’s review.

  • Black screen
  • Holding power button down for any length of time does nothing
  • plugging in to USB port of computer shows A51 device
What kind of works, but not really

Yes it’s true that holding the power button and volume down button simultaneously for a few seconds (about three or four) will bring up a menu. The choices presented are

  • Restart
  • Power off
  • Emergency Call

There’s no point to try Emergency Call. But when you try Restart you are asked to Restart a second time. Then the screen goes black again and you are back to where you started. If you choose Power off the screen goes black and you are back to where you started.

What actually works

Continue to hold the power button and volume down button simultaneously – ignore the screen you get mentioned above. Then after another 15 seconds or so it displays a lightning bolt inside a cricle. And if you keep holding that will disappear and you have a black screen. Keep holding and the lightning bolt appears, etc. So let them go. I don’t think it matters at which stage.

Now hopefully you have realy powered off the phone. So then hold the power button for a few seconds like you do to start the phone after it’s been powered off. It should start normally now.

As the other posts say, when you see Samsung on your screen you know you are golden.

Conclusion

I have shared what worked for me recover my Samsugn Galaxy A51 from its Black Screen of Death.
