how exactly did this issue begin? after flashing a firmware or after you replaced the screen or something else?

Please the phone fell into water. I service it and heat with soldering paste and heat gun before it began to work or function with no backlight or screen black. The charging indicator light and vibration in the phone works perfectly, but no display.

You probably need to check the LCD connector
