iPhone 6 plus sáng một bên đèn màn hình 2018
step 1: measure the resistance at 3 sockets, if lost any line -> tracking and lifting wires (yellow frame).
step 2: If Any lines were short-circuited -> remove the capacitors (purple frame) on line.
step 3: When the screen was bright and device was heat (IC light (red frame) heat) or bright a while, then die -> replace the components (orange frame). Do not remove diot capacitor.
note: In reality, Most of IP 6+, the screen just bright one side, ’cause break base from IC light to testpoint (blue line) -> take off and measure, if lost resistance, then lifting it. With phones drop in water, most of them were rotten and broke the wire (yellow frame) on 20v line or combustion orange diot.
