Hi there !The arming switch pin accidentaly got shorted with brushless motor pin while everything was online. The IO system/ leds and main led on board got shut instantly.However, i can still connect board to computer, update, downgrade software. And nothing appears to be burnt out visually on the board.Board powers up and only PWR and B/E led turn ON. rest everything is OFF.How should i proceed with diagnostics?May be some diode or regulator shorted out.I checked the bottom regulator and diode. Regulator works fine and diode has ~3.3V across it.
