A couple months ago, out of the blue, my P3P camera failed to operate upon startup. Everything else seems to work, however the live feed to my tablet no longer works. I've literally flown the thing maybe a dozen times. I sent the Phantom into DJI, however since i'm 1 month past end of warranty they wanted $257 to fix it. I just had them send it back to me, and am trying to decide if i should try to fix it myself, or call it a loss. Anyone ever replaced the "Phantom3_FC300X_MAINBOARD_V7_PCBA"? If so, where would you recommend sourcing the part? DJI, or somewhere else? Thanks!
