Switch v2 motherboard issue with right joy-con

Nintendo Questions Nintendo Switch

Hello,

Some time ago my Switch fell down and since then the right joy-con won’t be recognised as attached. I thought it was an issue with the joy-con itself, but tried replacing it and then the rail, but the problem persisted. Then I decided to inspect the motherboard and found that there is an open pad where I suspect there should be a component. The motherboard model is the HAD-CPU-01, which I think is different from the HAC one in this regard.

I can’t upload files, but my board has three small components and an open pad below the connector where the right joy-con rail flex cable is attached.

I would like to know if there should be a component over there and, if so, what should it be.

Thank you in advance.

Here’s what I’ve found:

First and second components offer no resistance;
Third one is a 180 Ω resistance;
Fourth one is an empty pad.

So it’s an FB coil that I’m missing, thank you!

you could just make a blob of solder combine two pads together instead of finding a same value FB coil(unless you have a donor board then NVM)

Hello again, I’ve made the blob of solder, but now the console won’t turn on. I’ve tested for voltages in the battery (4.1 V) and the PMIC (~3 V). It’s been charging for an hour.

picture of your solder work?
does console turn on after you remove the blob of solder?
