Thank you. Will do. I also have ordered an M2 A2338 16/256 logic board with Touch ID unlocked/no ic as it was significantly cheaper (about 250$) from a reputable seller on eBay. I wouldn’t have done this if I didn’t need a laptop for personal use and having already invested in parts for an...
Eitherway - I must really thank you. Are there any other components worth replacing? Or at-least to try? I can’t even do a DFU revive/restore it likely is bricked.
No no, I had not touched the connector. The only thing, still the worst, is the cable disconnecting during parts pairing. Well what I can do is just try again with the new screen and report back to you. If the CPU is done for there is no point in me trying to replace it. I am not that well...
At this point - Im just lost. I did as much research I could do. From what you know how likely is the CPU at fault? I have also ordered a new screen just incase.
Updated: I re-tested the screens. No luck.
I have however ordered a replacement edp cable just incase.
I also just noticed - RP611 appears to have a crack. On diode mode I get when I probe RP611, I get .334V and on the other side I get a short(Buzzer).
Would you say this could be the issue...
Thank you for the advice - I have two screens. One known good - brand new screen aftermarket (which worked up perfectly until I did what I did) and one OEM screen which had lines showing up on the screen - still partially functional even if i fully cant see everything.
Both of these screens...
Hello again,
update: With the screen connected and power via cable,
up710 pin14 is also accessible through via tb462. - I got 1.78 to 1.8 V
up710 pin 4 at ta277 - i got 1.8V
up710 pin 11 i got about 1.79V
These are two vias that werent on the schematic i have - as in connected to the POI.
am...
Thank you for your response. I will do the needful and update you.
As for responding - I see two buttons. One reply directly to the recent update by you. And another by the box where you type. This would be confusing to any new user on your forum. It is not with the intent to quote an entire...
For grounded pins - it should be 0V - i understand your point.
About earlier, i understand my question was a little stupid as I actually misread what you wrote - the way I work is methodical. Even if I know the expected output I have the tendency to confirm it anyways. Since I don’t run a repair...
Thank you for your response. will check the pins 2, 4, 6, 24, 26, 45, 46 in diode mode aswell.
For pins 8,18,28 and 38 and pins 4,11,14 i check for voltages with it turned on as in plugged in with the power button pressed?
If possible please tell me if the expected values as listed above are...
JP600_PIN_32
Default
d
0.595
Red to ground: 0.581
JP600_PIN_34
Default
d
0.595
Red to ground 0.583
JP600_PIN_36
Default
d
0.587
Red to ground 0.583
Just updating as i get the expected values by testing by polarity (as per instructions red to ground - black to component)
At UP710
@4 - 0.549
@11 - 1.156 (red to ground - 0.556)
@14 - (unable to check as test point is underneath up700 - Please confirm if i am to remove component)
thanks again i appreciate it.

Hi, thanks for the warm welcome and thank you for your response.
I did indeed disconnect the cable when it was powered on with the battery connected. I feel extremely stupid about this.
I do think it is a 820 - 02020. It’s a 2020 M1 MacBook Pro 13 16/256GB
EDITED: confirmed it is a 820 -02020 A...
