iPhone 6 plus lỗi cảm ứng 2018
step 1: take a careful look at socket. It easy to break base ’cause the sensor wasn’t glue right -> correct or replace.
step 2: measure 2 sides of resistance (yellow frame), if lost 1 side, and had 1 side -> lifting it.
step 3: measure the capacitors (purple frame), if shorting -> isolate to shorting line, use zxw to support.
step 4: the capacitors and diots or wires (orange frame) were error -> replace (do not lifting) or remove.
red text: after done all basic steps, but it still doesn’t work -> replace oscillation and IC supply voltage follow order 1,2,3.
green text: With phones drop in water, take a careful look at the resistances (green frame) or rotten 1 side adapt voltage -> replace same value.
note: with our experience, 80% IP 6+ just freeze sensor and the screen was noise from top to bottom ’cause break base from IC sensor to sync 6 bases -> just take off IC and lifting from IC base to next test point, it will work. With phones rarely freeze and without noise -> most of them were error at LCD.
