Could 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.
Issue:
IPhone 6 displays black screen and DC power shows the
current flows normally but a little higher than that of
average working iPhones.
iPhone Screen Has Gone Black Step
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.

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.
Fix Process:
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.

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