Need help repairing Nintendo Switch Mariko after WiFi module replacement

Hi everyone,

I’m looking for some help or advice with repairing a Nintendo Switch Mariko.

After the second WiFi module replacement, the console stopped booting.

  • After the first replacement, only Bluetooth was working.

  • After the second one, the console won’t power on at all.

  • I also tried removing the WiFi chip completely, but nothing changed.

The console draws 0.1 A, and voltages on the MAX77620 are incorrect.

When I connect Picofly, it draws 0.18 A, the green LED lights up, and it reacts to power on/off, but it still doesn’t boot.

I’m attaching a photo after connecting Picofly for reference.

Has anyone had a similar issue with Mariko and can point me in the right direction?

Thanks in advance for any help or suggestions!
