My husband spilt some coffee and a bit was on the back of the phone and now the screen shows a black background with a question mark . He has dried the phone opened it up to check it was dry inside set it over the heat vent and it is plugged in for power. Still shows ?

Solution
Replace the phone, water damage, not turning on, dead device. Most likely the onboard memory is dead and the phone can't load the operating system since you are getting a display.
