Hi guys! I know this might be the wrong part of the forum, but I figured I'd have a higher success rate with asking people that are not afraid to take stuff apart
So, I bought a crashed Mavic Pro, front was badly smashed, front sensors, gimbal, shorted and burned camera board, torn ribbon cables.. I tried starting it up, and it just gets stuck on solid red light, no wifi or USB connectivity at all. I thought "well, that could be anything.." and placed an order for most of the parts that were obviously beyond repair.
What caught my attention here is that the motor startup motor-"jiggle" only moved the rear rotors, the front ones kept still.. Possibly an ESC board issue? And I'm fine with just replacing the ESC board as the prices are reasonable.. So I took the rest of it apart and found this.
After carefully cleaning the board and removing the shield for the wifi amp etc:
Now I cannot for the life of me find what those IC:s marked "S 20" are? Or the components between the antenna connectors and those IC:s? So, what would be the most likely culprit for blowing the IC:s (or possibly the IC:s are just damaged by the resistors blowing out..)? What are those components? I'm willing to have a go at replacing the components before ordering a new core board as they are not exactly cheap..
Feel free to move the thread if it fits better somewhere else.
Cheers!
