iPhone IC chip problems explained: signs and repair

An iPhone IC is a chip on the logic board that runs one task such as charging, audio, signal, Wi-Fi or the screen backlight. If the chip or its solder is damaged, that function stops: no charging, no audio recording or No Service. Software does not fix it; it is repaired on the board under a microscope.

Key points
  • An IC is a chip on the board that runs one function.
  • Knocks, bending and liquid can damage an IC.
  • The symptom shows which IC is faulty.
  • The repair is done on the board under a microscope.
  • For board repairs the outcome is given at diagnosis.

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.
