Hi, I have this board on which the USB ports relating to JF601 and JF600 do not work, or rather it works as regards charging, therefore input voltage, but it does not work for the output voltage, this measured with a USB meter in reverse to see if the ports supply voltage, while JG600 works...
Hi I have this board that has 20v and current that restarts continuously 0.060 0.010 A I performed the swap of the soc T2 and the ssd nand from the donor board, the board enters dfu mode but the process blocks without returning any error I have no voltage on PP2V5_SSD or on L9030 L9021 or L9020...
a2681 with liquid damage on LT400 and UC850 and JT400, both touchpad and keyboard did not work, I fixed UC850 and everything started working again but suddenly the keyboard stopped working, while the touchpad and feedback work perfectly, I tried replacing UT3A0 and it started working again, then...
Hi, I have this 820-01700 board, which I replaced with a donor T2. When I power it, the board is in DFU mode. Soc_dfu_statu is 1.8V. I try to restore it with Apple Configurator, but it gives me this error: "Unexpected device state 'DFU' expected 'RestoreOS'" Error 4014.
I checked all the AWAKE...
I have this MacBook that has a question mark at startup as if there was no operating system I enter the recovery but if I start the installation freezes and restarts if I try to enter the disk utility it crashes and restarts at the question mark, where should I start?
I have this card blocked at 5v 0.20A-0.25A PPBUS =10v unstable 3v8 aon =3.7 stable I don't get 3.3 LDO the liquid damage affects the MagSafe side, I solved a short on the ic that manages the audio jack 3v8 aon in diode mode and 0.56
I have this card which, if powered by JG600, restarts continuously and 0 to 5v with unstable amperage, however if it is powered by JF600/1 5v 0.37 and then 0.02 stable PPBUS_AON 1.5 and nothing PP3V8_AON
I would like to have some advice regarding the possibility of doing a swap of the processor and the NAND, is it possible to carry out the removal and installation of the M1 CPU without a BGA station, but with only the 861..
If possible, what temperature and speed do you recommend I use?
I have this MacBook that has these artifacts when turned on but it boots and the touchbar displays the choices I can't understand the lcd problem I tested it on another board and it works the only anomaly I found it on pp1v5r1v35_s0_gpu_mem that in diode mode 0.204 and on a working board it is...
Hello I have this machine stopped on the 5v 0.09A on the usb ports on the right and 20v 0.02A on the usb ports on the left, Also the voltages wrong at U7800 are unstable or they are in loop between 0V and the nominal value PPBUS 12.57
820-01041 with video problems turns on you can see the apple only a series of colored lines, I thought it was the typical problem of flex but I tried another good screen and it has the same suspicious defect a problem all gpu the tuch bar works and displays the keys, no external video
I have this card going on 20v but with 0.001A I discovered a short on pp3v3_s0_left lifting u8295, mo I can't find the component in short how many Volts should I use to find it ?
Hi, I have this machine where the internal video doesn't work, but I get the external video, I've already found myself in similar situations, and the damage seems to be a CPU data line.
I get EDP_PANEL_PWR_BUF_EN, EDP_PANEL_PWR_BUF_EN,
PP3V3_S0SW_LCD_R, DP_INT_HPD with their nominal value, the...
Hello solved the problem of Flexgate by replacing lcd, but it does not have backlight, here are some measurements:
PPVIN_S0SW_LCDBKLT_F = 13V
PPVIN_S0SW_LCDBKLT =12V
EDP_BKLT_EN= 0v
BUF_EDP_PANEL_PWR_EN= 3.40v
EDP_PANEL_PWR_EN= 3.10v
PANEL_P3V3_EN_DLY= 3.29v
