820-01041 MacBook Pro A1990 - PP2V5_NAND_SSD0 short to ground

[Saurabh]

Received condition:
Tea spill, damage near the NAND area. The Voltage was stuck at 5v.


After the cleanup:
- Cleaned the whole area. There was a lot of crap underneath the U9080, so removed it. 2 pins were gone.
- Connected power, 5V and 200mA, the C9080 was heating. Heard a crack, removed C9080 and C9081.
- Connected power, 19V and 65mA. But all the caps on the PP2V5_NAND_SSD0 are completely short to the ground.



Not sure what to do next?
In past, I have seen multiple A1990 with NAND short issues.

Overvoltage went from PPBUS_G3H to 2V5_NAND, through U9080.
SSD is dead now...

Did I cause this?
What should be done now? I mean, is SSD replacement a viable option?.

In my experience SSD short on this model is becoming one of the most common issues.
I searched on YouTube, didn't find any videos on this.

SSD died because of corrosion, not your fault.

 

[Saurabh]

Can we replace the SSD?

 

[2informaticos]

Hopeless project.
Apart of NANDs, must replace the controller, which comes in sandwich package.

That's sad
But anyways, thanks for your support.
