How to Repair iPhone 6 blurry screen after booting

The problem of blurring the screen after the iPhone 6 started has been bothering everyone. Today, we invited the VIP Pro Shop team. They have a good way to solve this error, please check the article below.

Remove the iPhone motherboard, we found the upper part is seriously deformed. For the iPhone blurry screen problem, first we need to measure the grounding resistance value of the iPhone display socket J2019 via digital multimeter, the resistance value all is normal. Since the resistance value is normal, next we need to remove the iPhone display IC U1501.



Measuring the grounding resistance value of the iPhone display IC J219, we found the A4 pin is shorted, A4 pin touch 5.7V power supply, it is connected to iPhone black touch IC and some filter capacitors. Because the upper part of iPhone motherboard is deformed seriously, and the iPhone black touch IC is easy to damage, so remove the iPhone black touch IC. Pic 2


However, it is still short-circuited after remove the iPhone black touch IC, seems it's not the problem of the iPhone black touch IC. Next we need to use QUICK 861DW hot air rework station to remove the filter capacitors that connect to it, after remove the filter capacitor C1577, the resistance value is back to normal. Re-install the iPhone black touch IC and iPhone display IC. Pic 3



Connect iPhone display screen, and the measure the iPhone 6 with DC power supply, turn it on, the iPhone 6 displays normally. Entering the IOS system, the touch function tested is normal, the repairs end!
