Well, it seems to officially be dead-
I have the board completely cleaned and dry, but it is not sending any power to anything- no beeps, no fans no lights- nothing. I have power on the board beside the main inputs, but nothing from there (probably some simple diode or something!)
So, I have to decide if I should
A. Buy a new board and hope my camera still works ($150)
B. Buy a whole new drone (probably an advanced at less than $600) then use it to test my motors, camera, gimbal- then sell the extra parts and keep the advanced.
C. Toss it, and wait for mavics to start shipping (and prepare the wife for another $1000 toy expenditure)
If I missed it above forgive me but how/why did your Phantom end up in the drink to begin with?
