Hi to all!

I have a Nintendo Switch that has a short on an output line of the max77621, I have isolated the track, removing the coils and capacitors from said lines, and I have found that the short is in the red circle in the image I added.
The question is, is the processor shorted, or could it be one of the capacitors?

Thx in advice!

I haven't heard many reports of the processor shorting out the voltage lines.
It is more likely a capacitor somewhere on that line.
If you have been modding it, maybe check if something unintentionally got bridged somewhere.
A colleague uses a thermal camera and injects a low current voltage into the line to see if something heats up more than it should.

Thx for answer thesjaakspoiler!

I have removed the processor, and the short is gone. I have checked the capacitors on top of the processor, and the short is gone. will play in the next few days, reball, =´)
