recently I was soldering a GPS module to my fc while still on th stack and some soldering fluid/ tinning fluid spilled to the esc. not knowing what had happened I went to power it on and it shorted on the underside of my mamba F50 pro, close to the battery lead inputs. so I cleaned it all w isopropyl alcohol and went to power it on and everything so working fine the esc isn't causing any issues. but on the fc mamba f722 app, the gyro light and Rx light's aren't being powered. they only become powered when the fc is plugged into a usb input. I have checked th connections and it appears to being good. I am thinking that it could either be some annoying deep connection issue or something got fried on the esc. if anyone has any tips on what to do that would be great, thanks. it's a diatone roma f5 btw.
