Hi All

I have a DJI spark which is not taking off. I have always used DJI Go4 app on my 12mini to fly this drone but now it simply gives ESC error and some vission sensor error. I have checked internet for ESC error and saw youtube videos where people have changed the kaput ESC with a new one but here the error is for all 4 ESC. I have one more spark with broken cooling fan and burnt motherboard but working 3 ESCs(motors) so I can swap the ESC with that one but replacing all 4 ESCs is not a sollution plus how can all these error appear all of a sudden.   

Let the screenshots speaks further. Request you all to please advise what best can be done here. Note - The drone is out of warranty and is like quite old, we used it for various experiments.

Hi Bahadur Bille. Thank you for reaching DJI Forum. I'm sorry to read about this issue you've encountered. To clarify, did the drone have any history of crash or collision incidents? In addition, was it disassembled and modified before?

Hi

Thanks for addressing the issue. Yes, the quad came in EMP range sometimes but it still worked for some more time but never crashed or hard landings since I have used my palm or soft grass always for landings.
As of now 3 of the motors beeps in a known pattern like they always do but shows the ESC error if I attempt to Arm it.
Let know if a teardown would help here as I haven't attempted to replace any of its components.
