My first post.
I am coming from repairing mostly MacBook Airs.
This is my first attempt at a Switch repair.
This unit won't turn on.
No water damage:
Drawing 40mA when plugged in.
I found one cap short near ALC5639.
This is a Realtek audio chip correct?
I am not sure if this is a related issue to the power on or not.
I will have to order a chip as I don't have a donor board.
Could this cause a power on issue?
I am planning on removing the ALC5639 and seeing if this short resolves.
I have already checked the USB connector continuity, it looks good.
However, near MAX77620H I found a bunch of short CAPS
The large ones are inductors so I assume those are good but 2-3 caps are short
See the image below.
This is a power management IC correct?
I was going to order a new chip for this one as it seems to be the responsible IC.
I was expecting the issue to be at the charging chip/M92T36
The Nintendo Checks.pdf document I found does reference that the ALC5639 has some direct input from M92T36.
Any assistance would be much appreciated.
