How to repair 5c touch screen problems after replacing it?

  •   It can be frustrating when you start experiencing iPhone 5s/ 5c touch screen problems, especially if it’s just after you’ve installed a new screen replacement. Luckily there are a number of ways you can try to resolve the issue. Before you can start fixing your iPhone 5s/ 5c touch screen problems, you need to first diagnose the problem. In this case it could either be the digitizer or LCD inside the iPhone 5s/5c screen replacement. How to fix the touch screen after replacing the LCD screen digitizer?


      The touch functionality and the image displaying on your main screen is facilitated by the Digitizer and LCD within the iPhone 5s/ 5c screen replacement. For instance, if touch is unresponsive due to the top glass being broken or nothing is being displayed on your screen, then this is the part the LCD and digitizer come in handy. The two usually come fused together on your iPhone 5s/ 5c screen replacement.


    1. Perform a soft Reset. In case your screen is only displaying white or black, then a performing a soft reset on your iPhone could be a good place to start. White or even blank screens after a screen replacement, typically mean that the internal software of the device may be slow in embracing the new screen. A soft reset is probably the easiest and most straightforward option you can try. This method will help you get rid of any temporary data that may be hindering the new part from fully functioning on your handset. To do this: While the phone is powered on, hold down the Power button. Hold down the Home button. Your phone will immediately power off and then restart itself.

    2. Make sure that the back light on the screen is on. If in addition to the screen not displaying anything, the screen’s backlight is off, then the LCD on your screen replacement may be plugged in the wrong way. Try to fix this and then confirm that the new screen is fully set up.

    3. Alternatively, if the problem is related to the digitizer and touch is completely unresponsive, try to repair it and check that the cable is not too pressed together. Crumpling may bring about tiny fractures in the thin metal within the flex cable. Once the metal experiences these cracks, the distribution of power along with any other impulses along the device is made difficult.

    4. If your issue isn’t any of the above, and only entails a certain grid of icons refusing to work for example those on the left or the top third, then the alignment of the cables may be uneven. To resolve this, simply open your iPhone 5s/ 5c handset and make sure that the flex cable’s connectors are aligned appropriately. If you find that the plug is off center, then that may be the cause of this issue, which is commonly referred to as blocking. Blocking also occurs when your motherboard or digitizer cable have pins that are missing or folded. In order for your device to be up and running once again, you need to put the pins back in place.

    5. If you’re display is experiencing blotches, then it means that too much pressure has been previously placed on the LCD. Once again open your device and check to see that there are no residual pieces of glass left behind from the original screen that broke. Clean the screen then afterwards, turn off your device’s Sleep mode and then plug your iPhone smartphone onto a charger for up to 24 hours. The heat brought about by the continuous charging will result in the crystals within the device moving back to where they belong.
