Bought a damaged ph4 pro v2 from Ebay. Description was flown twice then crashed into a tree landing. Drone lights up and connects to remote but no start up tones no errors in screen but doesn't report battery voltages or any drone info or gimbal. Also on connection wont let me name drone. Found the 2 damaged components i think mosfets on downward facing board and a broken cable as in pic. Also the white staining is that water damage ? Replaced the board and cables and cleaned with IPA and toothbrush all connections that i could get to. Also updated firmware on drone, remote, and battery this all went fine used pc to do this. Started drone up again but before remote connected smelt electrical burning so quickly pulled battery. on a plus note the gimbal did its start up dance this time but still no tones from drone. Anyone suggest where to go from here don't want to fry more boards. Thanks
