Huawei P10 plus green stripes?

The cell phone went perfectly and was connected to the charging cable this morning and after seeing only a black screen with a vertical green stripe

Does anyone have any idea what that might be?

(Mobile phone has been restarted several times)

Need a new display

What have you already done for repair attempts? First turn off completely and restart. If the battery goes out, remove it this time. (20-30 seconds)

If that does not help, you can do a complete factory reset (factory default)

If all this does not help, it will probably be broken.

Greeting Steffen

So far always only reboot tried, and again to the charging cable.

How can I perform factory reset if I can't access my phone? 😳

Since the display is broken, because you can't do anything yourself, it has fallen down once or have you hit the phone accidentally against something once?

Well, if the restart looks like that's difficult. If the battery goes out, then try that again.

Factory reset, loud google

Hard Reset: Reset Huawei P10

Turn off the Huawei P10, and then hold down the [Power] button and the [Volume up] button…
Now a primitive menu appears, in which you have to navigate with the volume buttons to the entry "wipe data / factory reset".

If you can't see anything yet, try it analogously to the video: count how many times the button presses and do it like him.

would be nice if you give feedback, obs has worked out. Otherwise, I can't help you.
