Yes I let the board sit for 30s or so

What should I do now?

Okay: L7130- 12.79 L7520- 5.18 L7320- 1.71 L7310- 1.70 L7630- 1.06 L7430- 1.36 L7710- 0V L3095- 0V hope those help. What a frustrating board as it’s so close to working with the cpu heating up, fan spin etc… BTW I also noticed R6131 wasn’t on the board near the SPI flash. Is that always not...

Okay issues are sadly still there. Machine occasionally just turns off while using it and after a night in sleep I once found it back on the login screen after a reboot. No error messages though...

What should I check? There are tons of voltages...

Yes. You mean Voltages on U1950?

Also I’ve noticed pin 2 of R1950 seems to be at 3.3v for about 14s (estimate) before falling to 1.8. Same at Pin 1 so PP3V3_S0 is falling

Well isn’t that Pin 3?

Also super strange is the fact that pin 2 on R1950 occasionally shows 1.8V despite using the 1k resistor. If I unplug and replug power it fixes it

And for U1950 we get: Pin 1 - 3.3 Pin 2 - 3.3 Pin 3 - 3.4 Pin 4 - 0 (GND) Pin 5 - 3.4 Pin 6 - 3.4 Pin 7 - 3.4 Pin 8 - 3.4

It’s 1.070V. Also now know why the jumper, pad 2 was torn off the board

Also still wondering why someone who worked on the board before me ran a jumper between Pin 1 of C1297 and Pin 2 of L1295… Someone seems to have already given up on this one or it failed later

So with the 1k resistor it has about 3.3V on both sides of the resistor. Still doesn’t work though… No display or anything.

Well the board has seen liquid damage but the are looks fine. I’ll check the chip again and if not try the 1k resistor

Yup. Tried two more and no change.

Yup I do. Pin 2 is 1.7 and Pin 1 3.3

Okay so I changed it and R1950 but still stuck at 1.7V on R1950…

Quick question: Is U2100/U7950 on the 820-3332 compatible?

Okay so any old programmer supporting the "normal" EFI chip can also write to the T2 flash chip?

Hi, so I have an interesting problem. Got in a liquid damaged 16 Inch MacBook Pro for a customer for board repair. Well there is no fixing this thing, it is toast. I sold him an exact replacement 16" as I had a used one. Well he called me next day saying his professional software he uses for...
