The screen is black, but the phone works (even the touchscreen).
Texto:
My P20 Pro turns on, sounds, receives calls, and even the touchscreen works (I can get to the dial and it makes sound when I touch); but the screen is pitch black.
What I tried:
* Restarting it to see if it’s a software issue. It restarts, but the screen is still black. I even tried to go to recovery or bootloader and the screen still is black.
* Opened it up to see the screen connector. It wasn’t loose, nor dirty or corroded. I cleaned it up regardless, but still it doesn’t work.
+
So, I want to know if someone has experienced something like this… I don’t know if it could be a screen problem (since it’s in mint condition and the touch works), or it could be something related to the motherboard.
Any ideas? Thank you in advance![br]

I checked out the screen for a backlight issue, and I didn’t saw any images, but I noticed this blueish line underneath the phone, followed by a faint dark thick line. It covers the whole bottom of the screen. Could that be signs of damage of some sort?[br]

It also goes up a bit from the side.

'''A CHANGE OF SCREEN FIXED THE ISSUE.'''[br]

Before the change I fully opened it up, and it showed that water entered from the bottom right speaker. The mic board was fully corroded, and that blueish line that I saw inside the screen was indeed corrosion.
