How to tell if a charging port is corroded: look and symptoms

Corrosion in a charging port shows as a green, bluish or white deposit inside the port and darkened pins; a grey, felt-like build-up is usually lint. Switch the phone off and look into the port with a torch. Charging that cuts in and out, a moisture warning or a cable getting warm can also point to corrosion.

Phone works but the screen is black: what to do

If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
