All you need are some Mobile Phone Repairing Tools.

All models of iPhone till now have a separate IC called “Touchscreen Controller” to handle the job. However, Part Number of the IC in different Models of iPhone is different but their location on the Logic Board and Function is same.

Here I explain step-by-step easy to understand process on how to solve iPhone touchscreen not working properly problem. The same solution applies to all models of iPhone including – Original iPhone, iPhone 6, iPhone 5S, iPhone 5C, iPhone 5, iPhone 4S, iPhone 4, iPhone 3GS, iPhone 3G.

iPhone Touch Screen Not Working Properly or is Unresponsive – Problem and Solution

  1. Using precision screwdriver, carefully remove all the screws from the housing of the iPhone and keep them at a safe place.
  2. Remove all the screws from inside and carefully disassemble all the inside parts until you reach the Logic Board of the iPhone. Remember the sequence of disassembly. This will be helpful when you assemble back the iPhone.
  3. When you look at the Logic Board of the iPhone, you will see an IC similar to the image above. Remember, different models of the iPhone will have different part numbers on the Touchscreen Controller IC. For e.g., the Part Number of iPhone 4S Touchscreen Controller IC is – TI 343S0538.
  4. Dry solder could be one reason for the touchscreen problem. Using ESD-Safe Brush, apply good quality no-clean flux on all sides of this particular IC.
  5. Using Hot Air Blower, give hot air all around the IC. Make sure to give hot air from some height. If you give hot air from too close then the solder can melt. Our motive is to not to melt the solder but to remove all the oxides from the solder joints.
  6. Now using any good PCB cleaning chemical like IPA solution, clean the logic board with the help of ESD-Safe Brush.
  7. Assemble back the iPhone and check the touchscreen. It should work now.
  8. If the problem is not solved then you may have to replace the Touchscreen Controller IC (SMD).
