Hardware Nintendo switch - no power - goes to 15V 0.49A direclty

[needles]

Had another one. No luck with fuel gauge,

Disconnecting battery + plugging it back in gives battery charge symbol briefly, Nintendo Logo like it wants to boot, then black screen + 15V .5A

unfortunately, i have removed CPU, and the short clears. think this generally means it's dead/bad cpu. perhaps not all destroyed, but certainly needs CPU reball/replacement. equally strange and disappointing.

Bit late now, but I've read reflowing /replacing the WiFi chip can help with a switch that boots to the logo and goes off?

i have another one i can attempt it on and try it.

I was able to finally fix one by replacing a series of components near the battery charging chip. I also had another one where it was other parts near Power Chip. I think it's completely random in every case. I got 2 of them going again. I wish i had a solid answer for people.

Thanks, I will try to replace it too.

Same issue (15V 0.49A no power no display), but since the switch was a little bent I removed the motherboard and tried reflowing the RAM modules and It worked. I guess there were some soldering cracks and reflowing fixed it.
