  • If your camera still fails to perform then check with any other working camera.
  • Now check Resistor – 1, Resistor – 2, Resistor – 3 and Resistor – 4. If any of them is faulty then replace it.
  • Now replace diode, you need to replace it as you cannot check whether it is faulty or not.

s4 camera ic, capacitor and coils

  •  Now check connection between Resistor – 1 with Capacitor – 1 (Capacitor – 1 is at the other side of the board).
  • Check Capacitor – 2 and Capacitor – 3, replace if any of them is faulty.
  • Now check Coil – 1 and Coil – 2, if any of them is faulty then replace it. You can also use Jumper wire instead.
