Sometimes we will run into the phone is broken, it is very upset for our life and work. If you worry about iphone 6 display black screen and high-current, and when it comes across what can you do. This article will introduce you some guide to solve this problem.

IPhone 6 displays black screen and DC power shows the current flows normally but a little higher than that of average working iPhones.

If you are ever to come across any glitches or temporary bugs on your iPhone, it is always recommended to restart it, as you would a computer. iPhones don’t have a dedicated restart button so there is a certain command which is holding the power button + home button together for 10 seconds. This will restart the iPhone back up and sometimes can take up to 1 minute. You can not loose any data, contacts, music when doing the restart. This step is successful across all forms for trouble shooting on the iPhone whether it be for sound, camera, display, reception and so on.

If the iphone 6 no response,either. You maybe need fix it, the fix step is very easily, please follow me.

1. Teardown iPhone and measure the diode data of each pin of display screen interfaces. The data is normal. There is no output after measuring the display power supply ±5.7v voltage.

2. Replace the display screen power chip U1505, but the same problem still shows up. Therefore, we conclude there is something wrong with the surrounding circuits’ resistor-capacitor units.

3. After carefully measurement we find capacitor C1554 is short circuit.Replace it, the ±5.7v voltage output is normal. Assemble motherboard and turn on iPhone, the screen displays normally. Trouble is removed.

That the voltage of capacitor C1554 is under 5.7v suggests the damage of Touch IC chip or low starting conditions.
