Nintendo switch v1 - No power and Shorted caps but why?

Hi everyone,

I need some advice…
In theses below images, I have continuity to ground on the red arrow connections.
I didn’t find others.

I removed the USB-C connector because some pins were bent.
This didn’t solve the problem.
I removed the max77621aew1, M92t36, pi3usb and bq24193.
This didn’t solve the problem.

I don’t know what to do next. I already have a lot of work to solder all these chips again.
(Well, I think it’s good training)

Thank you for your advice !


that cap is on 1.8v line generated from max77620, remove and check for short again

Thank you for your help.

Do you mean the cap near max77620 ? ( It’s so small ! )
Because I tried to remove the one near M92t36 and it wasn’t that.

No, I mean remove max77620, the ic itself. If you looking to remove individual cap one by one to figure what is short, I wish you good luck and hopefully wont make you all the way to cpu eventually

Oh, the max77620, okay. I was thinking of max77621, that’s why I thought you were talking about removing the cap.

Thanks for your help, I’ll try that tomorrow.

It is still shorted after removing the max77620 …
