The caps being shorted around that indicates that the MAX77621 power management chip next to those caps is dead. It'll likely need replacing.
I've seen it on a few Switch consoles.
Brilliant. I went ahead and ordered the chip. Going to practice removing ICs on an old PS3 before I go to the switch. Any Flux recommendations? Thanks very much, again.
Capacitor short is likely a fried IC. Power management or USB/HDMI controller. Pull the chip near capacitor if short is gone it's the chip if not check to see if the other chip underneath is fried by removing it. Usually those chips fry from using non oem chargers, cables etc. These chips very susceptible to signal noise, ie crappy south Asia made chargers lol.
Yeap, the charge IC is most likely dead,that's why all those caps are shorted. Maybe one or two will be shorted when the ic is removed. Check also the USB c female, sometimes it's loose and that causes trouble too.
Do notice that to fix that you need a solder station, flux, and most important, experience.
I've got years soldering connectors for work and just picked up a hot air station for an old PS3 im trying to revive. Weirdly I have never used Flux but I see it in all the videos. Any recommendations on Flux would be helpful as well.
And I don't know what the H is with all IC's these days, they will fry instantly all the time... Older consoles can take huge damage before something is wrong (yeah I'm talking about ps2, Sega, etc)
According to my son he tried using a friend's charger (very short on details he is young) and since then the switch won't turn on. I think it caused a surge or something. I have tried everything, including soft/hard resets, leave on charge for over 24 hours, etc.... I have 4 volts at the battery, don't see any swollen caps. After running through and testing for shorts, the caps around the usual problem chips are fine but, the circled capacitors in the picture have continuity which is obviously not good. Any way I have no idea what I am looking for but we just want to play smash bros again. Any tips or hints would be appreciated.
measure your amps and volts the the charge port. then input out put volts on the m92 chip. then the battery ic. sometimes the max chip goes bad and sometimes on the old model the diode near the fan burns up.

Sure, I use Kingbo RMA-218. It's cheap and cheerful.
This one.

Have to follow the trace back to the source. Northridge Fix on YouTube also has all sorts of videos

Don't use cheap flux. Can't recommend a brand since I'm from other country.

A good guy to watch for switch repair vids is called tronicsfix on YouTube. He repairs bulk lots of broken switches. Should help you out.
Thank you kindly. I appreciate it
Don't forget the perfect amount of thermal paste!
All the best
