I´m pretty new to the switch game but i do have experience with microsoldering and diagnosis of iphones and macbooks. I already fixed a few switches but I´m stuck with this one.
It looks like it has some liquid (coca cola?) spill. Board looked clean except the eMMC had some liquid between the pcb and the chip and there was some under the fan. I did clean both and gave the eMMC a good reflow but the console won´t start. no shorts on any of the caps.
It charges with 1 amp, i get the battery sign and then reboot and repeat. When i disconnect the eMMC i can inject payload and start Hekate. When i then connect the eMMC i can access it with Hekate and it looks ok. After reboot with Hekate i get the Nintendo Screen for 1 sec then it shuts down and doesn`t reboot.
I can’t get it into recovery mode by pressing the 3 buttons.
