Help!!! I have Phantom 3 4K and problem - at 30-40 m height loses a video, after another 20 m and the RC stops. I'm looking for a SERVICE MANUAL to be able to locate the problem, I already bought a  second RC, but my problem is still the same. Thanks.

Don't think you'll ever have any luck ever finding a service manual for any DJI product.  They just don't do those.

and in workshops how to repair drones if they do not have such guides

I hope you're not flying it straight up.  If so, that may be half your problem - the other half being you're not aiming correctly.

Good luck

I used the drones correctly, at first it was flying well, after about a year the problem appeared suddenly, did not fly in wet and cold weather.

You need to make special precautions for winter flying or dreary weather missions.


Keep the flight battery warm, let the drone warm up a couple of minutes before flying off.
With a keen eye on the battery voltage, frequently.

These drones aren’t really made for flying  in the wet conditions.
Be very careful.

If you had a service manual, what would you do?


You aren’t a DJI tech, so not sure where this would lead.

if i have a manual, i will know which circuit boards connect to the RC and transmit the video signal to the phone. The drone has never flown in bad weather, but only in dry and calm weather.

Hi tsvettydjs, we're sorry to read the troubles. Just to verify, will the video and RC signal lost at a close distance in every place? If yes, I'm afraid that you may consider sending the unit in for diagnosis as we do not recommend to repair at your end. If you need further assistance, please start a case from here: https://www.dji.com/support thank you!

Interesting. I would never attempt such a feat.

But you obviously have more experience and bravado, for such tasks.

In the service I turned, first said that part 124 had to be changed, then they said they had to go to part 123. I can not believe I think they're cheating me. And these two parts are as expensive as a new drone.

Search YouTube for "Phantom 3 Service Manual".  There are some DJI videos available.

thank you, and that's it

That's unfortunate to hear. Which part needs to be replaced depends on the damage assessment. For flight safety, we sincerely suggest you consider the above suggestion. If there is anything else we can help, feel free to contact us.

Drones did not have catastrophes, the next flight did not climb to the specified height of 100 m, at 48 m lost a picture, so I did not see what I shoot and where the drones go. Since then 5 months have passed, the problem is not resolved. I'm going to buy another drone from another manufacturer.  Unfortunately, DJI did not meet my expectations.

Good luck on finding one that's comparable.  I bet you'll be back.
