Repair iPhone 7 Plus Motherboard Cannot Turn On

Ms. Aymie came to our shop with her iPhone 7 Plus that cannot be turned. The source of the problem is unknown and we need to further inspect the device. Firstly, we inspected all the device’s component and did not find any faulty component. Secondly, we inspected the motherboard and found some corrosion. We also were able to point out the problem which was a malfunction capacitor IC. The capacitor IC is placed nearby the corrosion area. Next, we removed the capacitor IC by applying heated air around the capacitor IC. Then, the device was reassembled and we tested the device thoroughly. Lastly, the device was working normally and we returned the device back to him.
