Good morning everyone, I’ve got a problem with a Nintendo Switch console that was brought into my workshop. I should mention that another repair centre had installed a PicoFly using the ‘kamikaze’ method for the D0.
The power button on the console isn’t working; I can switch it on by connecting the USB power supply (once it’s on, I can disconnect the power supply). I’ve obviously tried another flat cable that definitely works, but nothing has changed. I’ve inspected the console and found no signs of damage, but I did find a lot of copper dust scattered across the mainboard. I cleaned everything I found, but nothing has changed.
The second problem, which I only noticed later, is that the Bluetooth isn’t working. The Joy-Cons stop working as soon as I disconnect them (though they work when disconnected on another console), and the console doesn’t detect any Bluetooth headphones when I try to search for them in the ‘Bluetooth Audio’ menu.
I carried out another visual inspection and I think I’ve found a problem. This component appears to be damaged; when I measure it in diode mode, I get an open-circuit reading (1). According to a .pcb file I found in the archive, the component is marked N64771 (package C-0201). I don’t currently have a donor board to try and replace it. Does anyone know what component this is? It is connected to pin 35 of the ALC5639 chip. Could it be causing the problem with the power button or the Bluetooth?
What could be the problem? What’s the next diagnostic step?
