I’ve been trying to fix this Switch for a long while now and I’m out of ideas at this point. When I got it, I immediately noticed the USB port was ruined, so I tried replacing it. This unfortunately didn’t go too well, since it was my first hot air station attempt - all upper row traces were torn off. I did however manage to connect everything as it should be and checked continuity with a multimeter - all seemed to be fine. The console still did not turn on. I opened up my working one and charged the battery of the dead one. It booted into error 2101. I’ve read that replacing M92T36 might help fix that, so it was the next thing I did. The error went away and the console appeared to be working, but it still wasn’t charging. What I found next was that there are these diodes on both sides of the board, that can sometimes cause a no charging issue. On the side with the CPU, with the port pointing upwards, they’re located below it, to the right, next to the shield. On the other side, port pointing up, they’re to the right of it, below the screw hole. Not all models of the Switch have them, and it was apparently fine to remove them, so I did. After this, it started charging, with both a phone charger and the official Nintendo one. The next step was the dock, and this is where I’m stuck. When I put it in, the dock light would blink very irregularly, the console’s screen would stay on and the battery would charge. I assumed it was a fault with P13USB, even though there were no shorts on it. I replaced it, but it made no difference. I then thought that maybe I damaged the chip or it was already faulty, so I replaced it again. What I didn’t notice, was that I accidentally moved a capacitor next to the chip in a way where it interrupted a connection. Port pointing up, there are two tiny, beige capacitors to the right of the filters leading to P13 - it was the left one of them, on the trace that leads to the first point of the right side of P13 (I would post a picture but there’s some issue with embedding). One point on the P13 chip also didn’t form a connection, although I cannot remember which one it was. I tested it like this - the console screen actually went off and the LED on the dock stayed lit, but the TV was not receiving a signal. I took it out and inspected what I did, finding the two things I described and fixing them. This brought me to the same point as earlier - flashing dock LED, console’s screen staying on and the battery charging. Does anyone have any idea what else I could do to fix it? I greatly appreciate all help in advance.
