Frozen or\u00a0Touchscreen\u00a0unresponsive \u00a0is one of the most commonly seen cases in iPhone repair. Generally speaking, there are two different causes for iPhone x touch screen unresponsive. Malfunction of rails or components on the motherboard. Or touch failure caused by malfunction of the screen, which can be easily fixed by replacing with a new display assembly.<\/p>\n
Today,\u00a0we\u00a0are\u00a0teaching\u00a0you\u00a0how\u00a0to\u00a0rule\u00a0out\u00a0and\u00a0get\u00a0the\u00a0problem\u00a0fixed\u00a0by\u00a0starting\u00a0with\u00a0simple,\u00a0then\u00a0complex.<\/p>\n
We don’t know where the problem lies. On screen? Or on the motherboard? So here we use a simple way to make a preliminary\u00a0judgment first. Replace with a new undamaged screen! If it works fine on this phone board, we can confirm that the problem is related to the screen. As\u00a0 iPhone X screen digitizer assembly<\/span> is expensive, it\u2019s not that cost-effective for customers to change a new one. So let\u2019s try to fix it.\u00a0\u00a0Cosmetic inspection goes first!<\/p>\n We can see that the touch flex cable is not fractured, and the touch connector also looks fine. There is nothing unusual on the bonding area between the touch flex cable and the display flex cable. Judging by this, the fault is probably caused by the touch IC or the screen itself. So let\u2019s start with the touch IC.<\/p>\n Stick High-temperature Tape<\/a> around the touch IC. Then place a thermal insulation gasket under the touch IC. Heat with the Hot Air Gun to remove black adhesive around the touch IC.<\/p>\n Once done, pry up the touch IC. And then clean the bonding pad. Once finished, apply some Paste Flux to the bonding pad. Get a new touch IC in position and solder with Hot Air Gun. Clean with PCB Cleaner after soldering.<\/p>\n Now we can assemble the phone and test if the touch screen of the phone is back to normal.
