Good repair acticle, i want to presume finger touch can't detect the filter's temperature.The use of higher current with low voltage is additional gain to me, thanks for sharing.

Moshe: thanks man
if you look closely to the photos given you will see the solder pins on the bottom of the part and to solder the part on board you need a rework station..have a blessed day

Tayo: thanks man. thermal camera is a very good investment and it will be for itself. have a blessed day

this may be a silly question...but...i don't notice any gull wings on the filter chip, so, how did/do you solder it to the board?

Albert: yes I did as it is mentioned in the article. High current but low voltage. I used a thermal camera to spot the short, removed and replaced with a good filter. Have a blessed day

I recently purchased a thermal camera for just such a repair. Cant wait for it to pay for itself!

Probably because the original power adapter limits its current because of the detected short.
A preferable method also good to track shorts in laptop mainboards. And if such a short is for instance on the 19V DC input port we beside the higher current can also increase the external supplied voltage to the same 19V voltage. Or to the voltage that shorting circuit normally would need.

I believe those filters are often also used in tracks to USB ports.

Yogesh: thanks man. I do not have parts for the Nintendo switchs so I managed with this one. have blessed day
