Hello,
I have the following voltage behaviour when connecting the logic board through USB only :
- PP5V0_USB is fine
- VCC_MAIN jumps from 3.8V to 4.2V back and forth
-PP1V8_SDRAM : jumps between several variable values between 0.1V and 1.8V
-PP_BATT_VCC : jumps between several variable values between 0.9V and 3.1V then between 1.0V and 2.6V
The iphone suffered from water damaged and oxydation : I replaced C5202_RF, C5203_RF and C2441.
Thanks for any help on this,
