Yes the usb cam work good, the internal doesn't

Hello, I have restored the system several times with different Macos and still the camera does not recognize it.

ok got it, will tried to solve in that way, thank you

No, the Macos installed is the original Monterrey compatible with that model, i installed the older ssd and the camera still doesn´t work

Hi, i have a Macbook Air that the camera stopped working after a ssd drive change, i tried with smc and nvram restart and another 2 cameras and still doesn't work, with a external usb camera works good Volts J4002 Pin 12 5V Pin 11 0.9V Pin 10 0.9V Pin 9 3.2V Pin 8 3.2V...

Hello, I received a Macbook Pro 820-01700-A that does not turn on, the customer tells me that sometimes when he closed the lid sometimes the battery continued to discharge and sometimes it didn´t. One day it stopped turning on, the equipment has no knocks, no liquid damage and has never been...

Thank you for your help, i make the heat with quality flux and now its working.

i told you keeped in 0V PM_SLP_SUS_L 0V

i dont have oscilloscope but with multimeter show something when i conect the power wire and keeped 0V so i assume the signal PM_SLP_SUS_L its ok PM_DSW_PWRGD 3.4V PCH_DSWVRMEN 3.2V PM_BATLOW_L 3.3V PM_RSMRST_L 0V RTC_RESET_L 3.3V PCH_SRTCRST_L 3.3V PCH_INTRUDER_L 3.0V PCH_INTVRMEN 3.2V

3V3_S5 Present 3V3_SUS Not Present

ok, i changed the smc ic and now the lights turn on green and then orange without a battery connected, the fan does not start either

Sorry, i got a little confused since i don´t have much experience repairing mac and i literally searched for the line you asked me for. I made the measurements on the lines you asked me to 3V3_S5 0v 3V3_SUS 0v SMC_PM_G2_EN 0V

SMC_RESET_L 3.3v U5110 PIN 1 3.4V PIN 3 3.4V PIN 4 2.7V PIN 5 3.3V PIN 6 3.3V PIN 7 3.4V PIN 8 3.2V 3.3_S5 0v 3.3_S5/SUS does not appear in schematic Diagram

Hi friends i have a Macbook Air that does not turn on, it does not have liquid damage. F7140 voltage 8.1V present

What can i do now? I want to try everything possible. I've already checked all the bad sectors many times and I've checked all the voltages and resistors and I don't care if the board dies in the process but I don't want to give up please

I already reviewed the entire sequence and I have some doubts with these lines P1V1_SLPDDR_SOCFET_EN 1.8V P5VG3S_EN 3.3V P3V3G3S_EN 1.8V P5VG3S_PGOOD 1.8V All voltages are present up to the PMU_ONOFF_L line. When the power button is activated, the voltage of the PP3V3_S5 line is not generated

ok, I already checked the resistances related to ssd and they are all good, I tried again to restore and now it gave me another error How can I check the basic signals of the U9000?

There is some possibility of discarding by taking memories, this mac has 6 memories and I have a good reballing technique, so just tell me what I have to do and I do it.

yes i have the correct voltage on SSD coils, some of them have a little of damage corrosion, but it is only on the top not at the base where they are soldered.
