Hello, I have a trouble with a silver iPhone 6, that it has no image, even I changed the lcd, but the problem always exists, and by analyzing circuits to retrieve short circuits I noticed that the cpu is getting so hot, when plugging battery to the logicboard , so I removed the EMI shield and I noticed that coil inductors are little bit damaged, so I don’t know what should I do . Thank you so much. Here’s some photos : https://ibb.co/k9VJRa https://ibb.co/e1zjzv https://ibb.co/d6Gsma https://ibb.co/hj2bCF
@brahimeb, I believe you will have to check that voltage with the screen connected to get the 6v LCM_Boost from Chestnut
as well as L1519 boosting VCC_Main from 4.2 on one side to 6v on the other
Check FL2027 PP1v8 for 1.8, FL2061 PN5V7 for -5.7, FL2037 PP5V7 for 5.7, FL2035 (LCM_CHESTNUT_PWR_EN) and FL2036 (AP_TO LCM_RESET) for 1.8 with screen connected as well as FL2050 (PMU_TO_PHOTON_ALIVE) for 1.7 - 1.8
That is the fault of u2 ic.
