iPhone Touch Screen Not Working – Problem and Solution

 



iPhone Repair Vancouver If your iPhone's touch screen isn't working properly or is unresponsive, we'll show you how to fix it with a tried-and-true technique. These solutions work with all Apple iPhone models, including the iPhone 10, iPhone 9, iPhone 8, iPhone 7, 6, 5, 5S, 4, 4S, iPhone 3G, and all others.



A typical issue with iPhone touchscreens is that they don't work correctly or are unresponsive. The touchscreen problem might affect any iPhone model. The problem, on the other hand, is simple to solve. You may simply remedy this touchscreen issue in any version if you have a little DIY experience assembling and disassembling (opening) any mobile phone. Only a few Mobile Phone Repairing Tools are required.


To far, all iPhone models have used a separate IC dubbed the "Touchscreen Controller" to handle the task. However, while the IC's part number varies between iPhone models, their location on the logic board and function remain the same. Read: Apple iPhone Components


Here, I'll show you how to fix an iPhone touchscreen that isn't working properly in a step-by-step, easy-to-understand approach. All iPhone versions, including the original iPhone, iPhone 6, iPhone 5S, iPhone 5C, iPhone 5, iPhone 4S, iPhone 4, iPhone 3GS, and iPhone 3G, are compatible with the same solution.


Problem and Solution for an iPhone Touch Screen That Isn't Working Properly or Isn't Responding


Carefully remove all of the screws from the iPhone's housing with a precise screwdriver and store them somewhere safe.

Remove all of the screws from the inside and carefully disassemble all of the internal components until you reach the iPhone's Logic Board. Keep in mind the disassembly order. This will come in handy while reassembling the iPhone.


When you look at the iPhone's Logic Board, you'll notice an IC that looks like the one shown above. Remember that the Touchscreen Controller IC on different iPhone models will have different part numbers. For example, the iPhone 4S Touchscreen Controller IC's part number is TI 343S0538.


One cause of the touchscreen issue could be dry solder. Apply good quality no-clean flux to all sides of this particular IC with an ESD-Safe Brush.

Give hot air all around the IC with the Hot Air Blower. Make sure you blow hot air from a safe distance. If you blow heated air too close to the solder, it will melt. Our goal is to remove all of the oxides from the solder junctions rather than melting the solder.

Clean the logic board with an ESD-Safe Brush and any good PCB cleaning solvent, such as IPA solution.

Put the iPhone back together and test the touchscreen. It should now work.

If the problem persists, the Touchscreen Controller IC may need to be replaced (SMD).
