iPhone 6 Won’t Turn On – Water Damaged Repair
Press power button. It shows the phone won’t turn on. Then we take apart the phone and see clearly that the water damage indicator is red. Which indicates that the phone has been water damaged. Continue to disconnect the battery, and connect the battery connector with DC Power Supply. Press power button, the phone turns on with Apple logo. However, the screen goes black after 15 seconds and cannot access the system normally.
Current reading on the ammeter jumps to 510mA and then stay still. Which is abnormal? Normally, iPhone won’t turn on after water damage and accompanied with abnormal boot current issue is caused by short-circuited traces due to water damage of the board. So we need to further check the logic board. Since parts of the logic board bear obvious signs of water damage.
The first thing we do is to clean the logic board with PCB Cleaner. Once done, connect the battery connector with DC Power Supply and power up with trigger signal.
Current reading on the ammeter jumps to 220mA and then stay still. Which is still abnormal? So our previous cleaning of the logic board is not thorough enough. And we need to detach those moldy ICs and run thorough cleaning.
First, remove the shielding plate with Hot Air Gun. We can see clearly that U1501 and U1503 bear obvious moldy signs.
Heat with Hot Air Gun, and detach U1501 and U1503 from the board. Then apply some Paste Flux and remove tins. On the bonding pad with Soldering Iron. Once done, turn the logic board over.
Heat with Hot Air Gun, detach the two moldy components, U2402 and U0900 from the board. We can see clearly that area under U2402 has got seriously mildewed. Our initial judgment is that the fault is related to the seriously moldy area.
Apply some Paste Flux to the bonding pad. Then remove tins on the pad with Soldering Iron. Be careful with the components around when operating. If any of them got dislocated, we need to solder it promptly.
Continue to remove tins with resin-soaked Solder Wick. And clean with PCB Cleaner afterward.
Apply some Paste Flux to the bonding pad, and align new ICs to the right place respectively. Then solder with Hot Air Gun.
Tips: put it in the right direction
With Paste Flux overflowing and IC sinking continue heating for 5s. Also, treat U1501 and U1503 with the same steps. Once finished, clean with PCB Cleaner.
Now we can assemble the phone and test. Get the logic board and display assembly installed. Connect the battery connector with DC Power Supply. And press power button to power on, the phone turns on normally. iPhone 6 Won’t Turn On Caused by Water Damage issue fixed perfectly.
Warm tips: get the phone full assembled after confirmation of fault clearance
