BlueSreen Nintendo

Hello, I have a Switch with BlueSreen I already replaced the M92T36 because I detected a short, I already reflow the ram and GPU and nothing.
Continues with BlueSreen, then I detected a short there in the MAX77621 area, is that the problem? What is the MAX77621 for?
Sorry I’m new to these things

It generates the different voltages for the soc
Could be that that chip is the issue, because the processor needs multiple stable power supplys

Replacing it shouldn’t be too hard, just make sure that the pads on the pcb are all flat and even

I will replace that chip and see what happens
