iPhone 6s Plus lỗi cảm ứng màn hình
step 1: Measure the resistance of sockets. Incase, lose any lines, use zxw to tracking and joining the wires (in the yellow frame) together. If The wires lose resistance from both sides, open A9 or use IC source.
step 2: Measure the capacitors (in the purple frame), if it shorting, isolate it and remove slowly follow shorting line.
step 3: watch the resistance (green frame). If it error or damage one side by water, replace it with the same value.
step 4: 5v7 -5v7 5v1 connect with screen and turn on to export voltage. If it hasn’t, try to replace IC provide voltage 1 or the wire amplify voltage 2.
step 5: Attach screen with IC provide voltage is heat, if it not shorting, try to replace capacitors (orange frame).
IC source make freeze the touch screen but in reality rarely happen to IC source.
After all, take off IC provide voltage 1, measure the resistance bases. If it lose, use zxw to tracking the testpoint, scrape and connect.
From IP6S up, module induction has embed to SOC chip so most of them include voltage line (IC provide voltage) or the wires (in yellow frame) near socket just broke or peeling off.
In reality, when you find the common problems, please comment below, ICfix. Solutions alway try to improve everyday.
