Hi everyone,
      looking for some guidance on a recent problem Ive had with my P3(Pro). Had the copter since May of 2015 and never had an issue with firmware etc. When I updated to the most recent firmware however (1.6), I am presented with a "no signal" error on the top of the application. In attempts to fix it I have rebound the controller, downgraded firmware to both 1 version prior and 2 versions prior, tried different devices both IOS and Android while also testing a variety of cables on those devices, reinstalled the DJI go app several times and have tried sploodges method to forcing the firmare onto the craft. At this point im not sure where to go as I have recently seen other people with a similar problem. Any help from DJI or anyone would be greatly appreciated and thank you for your time.


(Photos attached for reference just incase im missing something) also the satellite signal is poor in the pictures due to it being indoors but outside yields the same "no signal"

Michael,

Send it in for repair - NOW.

I had this problem with a P3 Pro, I tried many things to solve this issue and eventually returned it for a refund.

I then had a P3 Advanced that also had many problems, then after one FW upgrade began to behave.
Wanting high res again, I upgraded the camera (and firmware) to a 4K camera. [beware, even though DJI people on this forum will do nothing to dissuade you from this upgrade, the folks at teh repair center will tell you otherwise]

After the camera upgrade, this P3P began having the No Signal issue - often.

I finally sent this in for repair (a horror story in itself) and eventually they replaced the video transmitter.

I've not flown it very much since getting it back, but have not seen the dreaded No Signal since.

Michael,

Send it in for repair - NOW.

Thanks for your reply, thats what I was hoping to avoid but after seeing several threads they all seem to end with sending it to DJI. Ive heard good things about their LA repair center though and since I'm in vegas hopefully down time isnt too bad.

Try downgrading to 1.5 and see if you get video. Then go back to 1.6. If it doesn't work, read the hidden files on the SD card.
If the file looks like the one below then that means the update corrupted the video transmission module and you will need to send it in.Call 818-235-0789 and it will be a warranty repair. Hopefully upgrading/downgrading will fix it, but it's a slim chance. Sorry about that.

downgrading to 1.5 was unsuccessful with it just giving out one continuous beep after about 1 minute of updating time. As far as I can infer it looks as if the craft needs to go back to DJI but I am by no means an expert at reading these files. Thanks again DJI-Ken for your help and I'll call that number tomorrow to begin the RMA process.

Yes, it happened to you. For some reason only a few aircraft upon updating it's corrupting the file and making the video transmission module INOP.
If your file, module 8 and 15 say "device Not Detected", I'm sorry but it needs to come in for warranty repair.

Just got my RMA was an easy and painless process just had a quick question about the instructions. It asks for a "proof of purchase" since I bought it from amazon would an amazon invoice suffice? Thanks

OK thanks for the help sorry to keep bugging you with questions, I got my RMA yesterday but there never seemed to be an accompanying shipping label. Does it usually take a couple days for labels to get processed and sent? Again thanks for your help also Wesley was awesome and helpful

After you start the RMA process, you fill out the customer information form and sent it back then after that you will get your shipping label.I see it pending a label, I'll make sure you get one today.

Sounds like the same issue i had.

It turned out to be a faulty USB port on my controller.
I sent it in and got it repaired :-)

Just got the email that ya'll received my phantom and by the time I looked at it, it had already been shipped out. Turn around time less than a day for a repair and only 3 days total is absolutely incredible. Thank You so much for your help DJI-Ken in solving my problem and congratulations DJI for having on of the most seamless and quick support systems.

Did they say what they repaired on it?  Let me know I want to be able to figure out what is the exact cause of these malfunctions and what parts are involved.

I basically knew what it was when I sent it essentially on a small number of phantoms, firmware update 1.6 caused the firmware in the camera to not recognize certain components which caused the camera software to brick. I believe this was the issue and they simply re installed the firmware however if it says specifically  when I get the craft returned I'll let you know

Just got the Unit Back looks like the replaced the camera unit which is great glad to see the issue is completely tackled however upon receiving the unit back I noted some major stress cracking that seems to have occurred while it was being repaired. Since its not safe to fly with stress cracks I'm at a bit of a loss what to do, do I file another RMA?

Due to a small change I can see on the fan and a new protective cover on the lense, I believe that they have replaced the entire camera and gimbal unit. This would make sense if the old one had been bricked by the software

Thank You, those stress cracks look bad.  If under warranty I would send back If not I would buy those reinforcement pieces that fit over them and epoxy them in place.
