    Nintendo Switch missing 1.8v

    Hello eveyone.

    I have a Switch that shows the blue screen upon startup but it sometimes will boot to the first Nintendo logo (once fully, only to bsod after turning off).

    The time it booted I was able to get 1.8v on the test pads near the backlight connector and above the MAX77621 right below the NAND/emmc chip.
    However, it not showing a bsod is rare and I'm not sure what is causing the rare boot that aren't bsod.

    Is it correct that the MAX77620 produces 1.8v across the board or do the two MAX77621 produce it locally?

    Basically, I don't think schematics or boardviews for Switch exist but any documentation of the system rails anyone has would help a lot. Any tips or info is also greatly appreciated.

    I know people often just say to reflow or reball the Tegra chip but I'd like to resort to that last.
    Thanks!
Working...
