Hi, I have an A1706 820-00239-A with no power. Only has 5V and 0A on ampmeter (all ports). Board has no signs of damages, and client said that it stoped powering on overnight. PP3V3_G3H = 0V and 0.002 on diode reading Diode readings U3100: PP3V3_UPC_XA_LDO = 0.453 USBC_XA_CC1 = 0.605...

Hi, I have an A1932 820-01521 that enters in DFU mode, but always gets an error before the end. Sometimes it says that he needs to install a software update (on the Mac with the Apple Configurator 2), I start the update, but at the end it says that it can not update , because nothing was found...

Hi, I have an A1398 820-00163-5 with no image. Nither internal or external. I have green light, CPU gets hot, have fan spin that increase RPM after a few seconds. All big coils have voltage, but USB tester doesn't show USB activity. Can you help?

Hi. I have an A1466 820-00165-A with no power. I have green light on charger but no fan spin, and only puls 0.2A from lab PSU. R8165 was burnt and ALL_SYS_PWRGD pad was gone, and I've jumped it to pin 4 of Q8150. PPBUS_G3H = 8.59V PP3V42_G3H = 3.4V SMC_RESET_L = 3.3V PP5V_S5 = 5V PP5V_S0 =...

Hi. I have an A1398 820-3787-A with no green light and no power. It had U7190 burnt and I've replaced it. Now, P5V1_VIN = 19.7V (shoulden't it be only 5V?) PPDCIN_G3H_CHGR was shorted, and after replacing Q7130 the short is gone. However, i don't have no power and no green light on charger...

Hi. I habe an A1707 820-00928 without backlight. It shows a very dark image, but I can see the Apple logo. External image is OK. I've already replaced U8400, but with same result. Can you help?

Hi, I have an A1466 820-00165-A with no power. It has green light, but it only puls 0.30A from lab PSU. PPBUS_G3H = stable 8.59V PM_SLP_S3_L = 0V ALL_SYS_PWRGD = 0V and no pulse. PP5V_S4RS3 = 0V No big coil seams to be shorted. PP5V_S5 = 5V PP5V_S0 = 0V and 0.457 on diode reading...

Hi. I have an A1278 820-3115-B with no power. It has no green light, no fan spin, puls 0.10A from lab PSU. Client says that some times it get an orange light in charger, and in those cases the mac powers on. Here it hasen't powered on any time. PPBUS_G3H = 12.27V PP3V42_G3H = 3.4V...

Hi, I have an A2251 that has no power. It puls 5V and 0.120A from lab PSU. It had PP3V3_G3H shorted, and after replacing U6903 that short is gone. However on PP2V5_NAND_SSD0 I have 0V and 0.095 on diode reading wich I think is to low (not sure). Already tried DFU but it isen't recognized...

Hi, I have an A2337 820-02016 with no internal image, and it had contact with a bit of liquid. LP670 was burnt, and CP677 was also burnt. After replacing them, I get 5.1V on them, but still no internal image. On external display i get image. Already tried a good display, but same result. Can...

Hi, I have an A2179 820-01958-A stuck in recovery mode. Already tried DFU restore, but it always fails, and goes to recovery mode. Board has no damages signs, and client said it stoped working overnight. Can you help?

Hi, I have an A1398 820-00138 with no power: PPDCIN_G3H = 20V With board alone on the bench, PPBUS_G3H = 1.098V, and 0.473 on diode reading. PPVBAT_G3H_CHGR_REG has 0.490 on diode reading. None big coil seams to be shorted. No visible damage on the board and no history available. Can you...

Hi, I have an A2159 820-01598-A with no power. It pulls 5V from ampmeter and 0A. PPBUS_G3H is shorted. It has 0.002 on diode reading. PPVIN_G3H_P3V3G3HRTC is also shorted with the same readings. Can I inject voltage there?

Hi, I have an A1466 820-00165-A with no power. Client said it stoped working over night. It has green light, no fan spin and puls 0.2A from PSU. C7500/03 are burnt, and the pads are also burnt (gone). PPBUS_S5_HS_OTHER_ISNS test pad is also missing. PPBUS_S5_HS_OTHER_ISNS = 8.56V on U7501...

Hi, I have an A2159 820-01598 with no power. First it was pulling 0.70A from ampmeter, and I've tried safe / target boot mode, and DFU restore without success. DFU gave a lost conection error. After DFU try, now I have board alone on bench, 20V on ampmeter, but 0A. PPBUS_G3H = 12.62V...

Hi, I have an A2141 - 820-01700-A rebooting. Client was covering the web cam with a sticker, but presured to much the sticker, that broke the display (and probably damaged the cam). Now the mac is rebooting, even with just the board on the bench, and client needs to recover his data. He...

Hi, I have an A1466 820-00165-A without power. (It takes 16V from bench PSU, and the amperage is very strange (oscilating bettewn 1~2A w/o battery). No fan spin, and CPU gets very hot, and thats with I try to don't take too long with it connected to the PSU. PP3V3_S5 = 0.002 diode reading...

Hi, I have an A1989 820-00850-A without internal image, and rebooting Already tried a knlown good display, but only have external image. I can see image in the external display, but it reboots afetr a few seconds. Client said that it stoped given image, but it worked on external display for...

Hi, I have an A1708 that only has image on external display. Client said that it was listening music, and the display died. Already tried 2 known good displays, with same result. Not sure if the problem is backlight or image, but I can't see nothing on the display, even with a flashlight...
