I got two used and scrapped Phantom 3 Standard drones that both had crashed. The first one I got working immediately by replacing the broken gray cable between the aircraft and the gimbal supplying the gimbal with power (interesting almost complete disassembly needed). The successful repair of drone #1 also prooved that the controller of drone #2 wasn't the problem. I linked the second controller successfully to the first drone and drone #1 has been in the air again.
The second drone seems to have the camera working ie I get video on the Dji Go app but no control and re-sync doesn't work with no light in the sync led (completely dark, no light). I think the drone was crashed by the previous owner but I don't know the history. My guess is that the 5.8 GHz receiver on the mother board is completely dead. Looking at the mother board through microscope I didn't find any faults. I think the most probable cause after a crash would be a damaged 16MHz chrystal.
Question: Any similar experiences? Does anybody know a source for the exact 16MHz chrystal (T160MnLD) or will any SMD 16 MHz chrystal work? Searching for an exact match based on code printed on the chrystal didn't provide a result.
Notice!
This is a plain hobby project trying to get an ancient drone to fly again. I presently have two perfectly working Phantom 3 Advanced drones so there is no urgency. I am pretty sure the easiest solution is to replace the whole aircraft's mother board but having the means of changing surface mount components makes a possible repair more interesting. Ideas are welcome.
