iPhone display IC repair: signs and process

On iPhones, some chips that drive the screen sit on the main board. When they fail, a new screen still shows no picture, light or touch. On LCD models, a failed backlight chip leaves the picture very faint. The repair is done at board level by soldering.

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.
