iPhone 6 Motherboard is Burned Out When Charging
When a smartphone like the iPhone 6 will suddenly not power on, there are three potential factors you need to consider. It could be just a simple battery power drain, a software glitch, or worst, an indication of a device being badly damaged. A customer said it has 1.4V current when turned off, and it cannot be turned on as the motherboard is burned out when in charge. Now vipprog will help you to fix the iPhone 6 motherboard is burned out and cannot be turned on when in charge.
Repair Process:
1. Plug the original charger, but it has no response. Tear it down and plug adjustable DC power supply. The current rises to 1.4A. I can feel that the chip is hot, which suggests that there must be short circuit. Remove the shield cover and put rosin on the charging chip, as shown in picture 1-1. The chip is obviously hot when energized and the rosin melts up.
2. Replace the chip and then measure the inductor. There is no short circuit now. Clean the chip and energize it to test. The current is normal. Assemble the screen and plug the USB charger. The charging icon is shown normally, as shown in picture 1-2.
3. Here, I recommend a USB current voltage meter. It is small and useful. It is convenient to check whether iPhone is in fake charge, as shown in picture 1-3.
