Trying to fix this MacBook Pro (16-inch, 2019), but no success.
Under thermal camera i found short on u9080 AND U8600
PP2V5_NAND_SSD1
PP2V5_SSD1_AGND

PP2V5_SW2_TPS62180_SSD1

There are probably more NANDs damaged.
These machines suffer a lot from SSD problems.

You should need to change all NAND chips I suppose.
Sometime is possible to solder less chips, changing original configuration.
All you need to know about SSD configuration can be found on pages 2 & 3.

That one has the lowest resistance to ground.
Once it removed, you may still get lower value than normal.
