SSD is not getting detected on macbook pro 1707. Checked for power supply in all NANDs. The diskutil is also not showing the hardware nand attached to the system The NAND power distributor is getting over heated but the power supply is proper. I have checked all the NANDs in the attached image for power supply.
Ouch! Sadly your systems logic board has a problem! It could be the flash chips them selfs failed a common issue with smaller drive setups which have too much stuff! You really need to leave 1/3 of the drive free! The larger drives need about 1/4. Otherwise the drive is over taxed. It’s also possible you have corrosion damage due to a liquid spill. Best to find someone local who have the needed Mac & micro soldering skills
