Hi,
What you are experiencing with your screen can be caused by certain scenarios that may include software issue.
To address this concern, we suggest that you perform a two-button shutdown. Here's how:
- Press and hold the volume-up button and power button at the same time for at least 15 seconds and then release both.
- The screen may flash the Surface logo, but continue holding the buttons down for at least 15 seconds.
- After you release the buttons, wait 10 seconds.
- Press and release the power button to turn your Surface back on. You should see the Surface logo.
If the issue still persists, follow the steps provided by CindyMonteiro from this link.
Get back to us with the outcome so we can help you out further.
Regards.
