Member: 129507 Status: Offline Thanks Meter: 10 | iphone 5 light problem after liquid damage I received an iphone 5 liquid damaged. After cleaning up the board I managed to get the phone to power on but no light on the lcd. After measuring a few components I found L3 (light coil) to be open so I replaced it. When I powered on the device the light worked for one second then went out again. I measured L2 again and found it open circuit again, so I have a short some where. Ive measured the coil pads one side is grounded. Ive check D1 and its working. So could the fault be the light driver ic U23 ? If anyone can help and point me in the right direction on how to solve this issue . Thanks very much. |
