Why iphone 5S display blue screen after
reinstall motherboard?
Maybe the screws on motherboard were
installed with longer one, so that broke the screw.
How to repair?
You will need microscope,
Special enameled wires, heat gun, blade, thinner, tweezers, etc. Special enameled wires
are taken from ear speaker or loud speakers.
Step 1: remove all broken lines remainder
from the position, with microscope, blade.
Step
2:
add enameled wires to the position where set screw, with
microscope, heat gun, tweezers; the straight lines are “blew” one by one,
even much smaller than hair, just can see clearly by microscope.
Step 3: clean. Done!
Kindly reminder: Do not exchange these
screws, otherwise will cause troubles!
Done!
Thank you so much :)
