PMIC Replaced - Missing voltages
テキスト:
I have an iPad Air (1st gen) which I have replaced the PMIC. The reason for that is because the iPad charges only when it was switched off. '''I have lifted the following pads during removal of the PMIC:''' * B17 * B16 * B15 * C16 '''Dont know If this is the cause of the problems below:''' * No backlight (filters are good) * Missing voltage on PP3V0_SPARE1 * Missing voltage on PP3V0_S2R_SENSOR * Missing voltage on PP3V3_ACC * No Heat on the board, and I can see apple logo on screen without backlight looping. Anyone can point me in the right direction or explaining those missing voltage lines could be a BIG help understanding the situation. Thanks :) + + + + [image|2264303]

I have lifted the following pads during removal of the PMIC:
* B17
* B16
* B15
* C16
Dont know If this is the cause of the problems below:
No backlight (filters are good)
Missing voltage on PP3V0_SPARE1
Missing voltage on PP3V0_S2R_SENSOR
Missing voltage on PP3V3_ACC
No Heat on the board, and I can see apple logo on screen without backlight looping.
