I purchased a crashed mavic 2 pro drone on ebay so dont know the whole story on her but he said she fell like 12 feet after hitting a tree and fell at the base of the ocean which i noticed water damage on the board. I was wondering if perhaps any one here could point me the right direction. The problem is shes not getting pass the motor startup. I have only 3 that are showing movement at startup and then that is it no movement on gimble or lights or startup sound. I broke her down and sonic cleaned all the parts to try and get off any possible corrosion. Any chance anyone have the schematics to these girls im trying to figure out the startup sequence that perhaps can pinpoint my problem. And wondering if that one motor not starting up is whats stopping her from advancing with the start up. I have another mavic 2 that’s fully functional so perhaps switching boards for trial and error would be the best way to find out where my problem lies. Appreciate any help and thoughts.
