I really hope someone can help.


I recently fitted a new screen to a iPhone 7 but upon start up the phone got to the apple logo and then restarted again. After searching the threads I thought it could be the audio ic which I tried to reball but there was no change so I put the phone aside.


Today I had another iPhone 7 and thought I could use the new screen however, the same thing happened with this second phone i.e bootloop ( the phones restore normally but then revert to a boot loop )




I had a look at the screen cable under the microscope and found a bit of solder touching ground and the top four pins ( I think they go to pins 1,2,3 and 4 on the motherboard )


I have checked the board and discovered at least pin 2 is short to ground which the schematics show as "I2C_Disp_EEprom_SDA_Conn"


I have checked FL4741, C4741, C4731 and FL4729 and all are shorted.


Can someone please help and give me some idea where the short is possibly coming from as I have two customers iPhone 7's to repair.


Thank you in advance
