Troubleshooting basic drone

[Seaofdep]

Hi , I have a propel orbit hd drone that was working fine, and after a rough landing I replaced the propellers. Tested and was working. The following day I turned on the drone and only 1 led out of the 4 light turns on doesn't blink for connecting to controller or anything. I have looked at many forums and found that propel is not the best at helping out or responding. So decided to pull out the dmm. I found that the working arm is receiving 4ish V and 2 of the non working are at 0.032-0.053 and the last is receiving no power at alll. I am not sure where to begin checking for the shortage and would appreciate any feedback and or help. Thank you

So just wanted to update this. I tried replacing smd and that shorted out on main board but even with a rework station it was difficult lol and ended up flicking of other components. When all hope was lost, I remembered about a micro drone with bad motors I had  (2x2). Long story short , I made sure mosfet can handle the amount of amperes needed to run bigger motors , modified and added long range antenna, soldered motors and new battery wires. Zip tied main board and now she flies
