Hi guys, I have an iPhone 6 that came in with several missing components near fpc home and fl2024. I proceeded to replace everything but still does not light up. When the power button is pressed the absorption reaches 0.06 and does not increase, I checked the main lines and I have all the voltages.

AP_BI_I2C_SDA: 1.8V
AP_BI_I2C_SCL: 1.8V
AP_TO_I2CI_SDA: 1.8V
AP_TO_I2CI_SCL: 1.8V
PP1V8 OK
PP1V8_SDRAM OK
Pp3V0_NAND OK
PP3V0_TRISTAR OK
PP1V2_NAND OK
PP_VCC_MAIN 4.2V
PP_VCC_BATT 4.2V
PP_CPU 0.86V
PP_GPU 0.05 (no short)

Can someone help me? Thank you

Try to re-solder CPU. It maybe caused by CPU pseudo soldered
