4 right controller PCB shorted, any ideas of what this component is?
Hello,
I have a right Quest/Rift S controller here that would not power on. Upon disassembly and inspection, I found that there was one component with a bit of a heat mark on the top. I put a little paste flux on it and connected power and sure enough it melted the flux within a couple seconds. My initial thoughts were that this is a resistor or filter of some kind, any help in identifying it would be appreciated. I'm not certain this is the component causing this short, but at the very least it's where the power is ending up.

That's an SMD inductor. Is it fully shorted, or does it have a small resistance? Do you have an LCR meter or component tester?

Hey, thank you for answering. It has a resistance of 0.7 ohms. I don't have an LCR meter, just a more basic multimeter, though I suppose I should pick one up. In the case of this being an inductor, that low of a resistance should be fine, right? So it must be something else on the circuit that’s just drawing too much power through this? Interestingly, the LED on this board has an enormous resistance across it in both directions.
Update: the chip on the board labeled "U8" with the text on top reading "LR2522 TI 9A8 AGQJ A" is getting VERY hot when the battery is connected.

Maybe it is just the angle of the picture but D6 looks puffed up and L2 looks burnt (or has a hole in it)….
Has D6 been tested in both directions?
What about C22? What is the resistance across it?
