Hi there.... My huawei mate 20 pro was water damaged!!! After a while its LCD was displaying green lines and in no time it went blank, but surprisingly the phone works and still receives notifications and incoming calls. I could even answer calls in a blank screen by pretending to swipe as if its on. My question before i buy a replacement screen . Is the LCD really damaged or its the logic board ? This might help me decide on how to proceed with it.
