step 1: Measure the resistance of sockets. Incase, lose any lines, use zxw to tracking and joining the wires (in the yellow frame) together. The double wires lose resistance both sides, open A9.
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 undisplay 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.
The phones are damaged by water,IC provide voltage 1 almost die “5s, 5c, 6, 6+ can replace for each other”. Other cases, the wires in yellow frame (near socket) often broke. Finally, open or broke A9. Not found that IC source make undisplay screen.
