Hey!

I got this BSOD Switch OLED on Vinted for cheap in hopes to practice kamikaze, but figured I might as well try to revive it so I went and attempted a reball.

Had a few issues with 0201 caps going haywire when pulling the chip, but I soldered back some new ones with all resistances seemingly in the right ballpark.

Console now boots up fine and everything I could test is working (5Ghz Wi-Fi included) EXCEPT for Bluetooth.

Obvious culprit would be the antennae cables as they look completely f*cked but what makes me doubt they're the culprit is that they still "work" as far as Wi-Fi goes (signal gets better when they're plugged in).

I am waiting for a replacement to arrive and test it out, but I do wonder whether they can be fixed by soldering a new cable in the meantime?

Before I fully end it I do wonder if there might be something else I've overlooked so I took a video from under the scope :

I am very much struggling at dissolving the flux I've used here (2UUL "EcoFlux") even under heat and IPA with cleanroom wipes (could an ultrasonic cleaner be a good purchase for cases like these?)
there's quite a strong "nick" in the PCB under the APU shield but it does not seem to have exposed copper or ripped traces
~~the cap left of the APU seems shorted to ground and looks kind of cooked~~ nvm its an inductor
I could only see one ripped GND pad top-left under the APU (pic) and did not notice anything else, didn't bother fixing it

Sorry for the long post but I've gotten so much weird sh*t happening on Switch consoles recently I figured I could use the help. 😬

[Switch OLED] No Bluetooth (WiFi OK) after APU reballing, clear antenna issue or failed repair ?
