A2141 820-01700 - Liquid Damage around NAND1 hits 50*C

[it-solve]

Lots of liquid damage around U9000 and U9080. Reballed U9000 as it was badly corroded underneath.

Getting 3Ohm resistance on PP2V5_NAND_SSD1. 410Ohm on a same board for comparison.
Lift up L9080/1 to check if caused by U9080 but there is no short on it.


PP2V5_NAND_SSD1 - 2.5V - 3Ohm
PP0V9_SSD1 - 0.8V - 452Ohm

Internal SSD failure?

Very likely.
You can try changing one chip only.
But be prepaired to change all NANDs.

Read this, may help you...

Hello everyone I actually read on the forum that is possible to fix ssd shorted on the line PP2V5_NAND_SSD0. I had quite an high number of SSD short with no repair. mostly of them 15inch board o 16 inch board from 2017 - 2019. So my question is if there is a solutions to this and is possible...
