I have checked it several times again but still nothing, with red probe on ground, I get OL.

diode mode to ground at EDP_PANEL_PWR_BUF_EN is OL and pin 12 is 3.3V

good day guys, I hope all of you are well, please have got an issue with my 820-00850 , it does not display on the internal screen ,but displays fine on external monitor, I have swapped with a different screen cable, and screen but still no changes. At U8510 EDP_PANEL_PWR_BUF_EN = 0.22...

Yes, am using an 87W charger , is there something I can check next ?

06.26 on diode mode to ground on 2 of the CD3215 and 06.9 on other 2 , on opposite sides , meaning when I flip the board one side I get 06.26 on both and when I flip to the other side I get 06.9. I get 1V1 LDO voltage at all 4 CD3215s

Will do that now , and about this signal being low CHGR_RST_IN, I suppose it has nothing to do , and also if the issue was a CD3215, would it work with the charger ?

hello guys, have got n 820-00850 that would not power on charger but works 100% on battery . I do not seem to fully understand the 2018 model of operation , I measure 12.30V on PPBUS with charger only connected and 5V in PPDCIN, I have checked for a short to ground but no short, the only thing I...

hello guys, have got an iMac with no resolution whatsoever, from start up the resolution is already distorted, all big icons , I can't change it as there is only one profile for the display even. I have replaced a different display but no changes . I have not dealt with a case like this before ...

Thank you , the post can be closed . The issue was as you pointed out at R5127, even though 3.3V was present in and out , there was a break between the resistor and pin 3 of U5110, I recreated the break and the board worked okay . Thank you so much

my bad , R5127 voltage is resent and pin 3 is 3.3V

I have replaced C5101 but no changes , with U5110 removed SMC_RESET_L is high below are the readings of U5110 U5110 PIN 1. 3.40V PIN 2.GND PIN 3.0V PIN 4.0V PIN 5. 0V PIN 6.3V PIN 7.3.3V PIN 8. 1.1 and drops gradually

have replaced 3 functional SMC, with U5110 removed it goes high

hello guys, Have got an 820-2936 that works fine with the battery , but once I connect the charger the machine would start to lag, and runs really slow , Q5300 voltage devision circuitry is working okay as well as Q5310, am not sure where else to look, please help.

good day guys , this board is making me go crazy, SMC_RESET is 0V , but when I remove R5110 it goes high , when I put it back its low, I replaced it, but no difference , I tried with the SMC as well as R7100 to rule out a faulty U7100, and even R5100 replaced , all with no changes , please where...

what can I do ?

I can see the drive too during the installer stage, but when I when through with the WIFI option , I didn't see the drive . Also , with the pen drive installer , once the drive has been formatted and I try to install to it , it would freeze and restart, I wish I can show you a video, but I don't...

I can do it from both

Yes I can

yes I did , just as you instructed, the original macOS was Sierra , but no internal drive found , so could not continue
